The MC72000 Integrated Bluetooth™ Radio provides a complete, low-power Bluetooth
radio solution. The design is based on Motorola’s third-generation Bluetooth architecture
that has set a high standard for interoperability, complete functionality, and compliance with
the Bluetooth specification.
The MC72000 Integrated Bluetooth Radio from Motorola implements the RF and baseband
host controller interface (HCI) of the Bluetooth protocol in a small 7 mm x 7 mm BGA
package. The MC72000 is the ideal solution for low-power, short-range Bluetooth
applications with small size constraints and includes superior performance features like a
dedicated Bluetooth audio processor module and on-chip memory. Debug and production
test are fully supported through the joint test action group (JTAG) interface.
The RF portion of the radio provides a unique combination of high sensitivity, excellent C/I
performance, and low power consumption. These performance parameters are extremely
important to maintaining a robust link in high RF interference environments created by
devices such as mobile phones, high density Bluetooth networks, 802.11b networks, and
microwave ovens.
The MC72000 uses an innovative, highly advanced packaging technique to combine two
die—the RF and baseband functions—into a single, cost-effective package. Motorola’s
optimized two-chip architecture avoids compromises between cost and performance that
other one-chip solutions must make. With Motorola’s integrated solution, customers get the
best of both. Each die is implemented in its optimal process technology to deliver low cost,
low power, and small size.

Figure 1. MC72000 Example Application Block Diagram
The main block is the MC72000, which will be described in depth in Section 5, “System Description.”
In addition to the MC72000, there are three other blocks:
• RF signal Path
• Interfaces
• Reference clocks
2.1 RF Signal Path
The switch for the RX and TX, the bandpass filter, and the antenna are all found in the RF signal path.
2.2 Interfaces
There are four bi-directional interfaces and one reset that only the host can initiate.
• The SSI interface is used for audio purposes.
• The UART interface is used for all communication to and from the host (for example, HCI
commands).
• The SPI is used for communication with the SEEPROM.
• The GPIO pins are used for different configurations set by the MC72000.
2.3 Clocks/Crystals
The MC72000 has two clocks:

• The reference clock (12-26 MHz) is used when the MC72000 is active. Note that for a crystal
connected to the on-chip oscillator, the frequency range is 12-15 MHz as shown in Figure 1.
• The low power clock (32.768 kHz) is also included and may have high initial tolerance.
3 Electrical Characteristics
The absolute maximum ratings given in Table 1 are stress ratings only, and functional operation at the
maximum is not guaranteed. Stress beyond these ratings may affect device reliability or cause permanent
damage to the device.
WARNING:
This device contains protective circuitry to guard against damage due to
high static voltage or electrical fields. However, normal precautions are
advised to avoid application of any voltages higher than maximum rated
voltages to the high-impedance circuit. Reliability of operation is
enhanced if unused inputs are tied to an appropriate logic voltage level (for
example, either VDD or GND), except for JTAG signals. Refer to
Section 10.12, “JTAG Interface,” for details on how to handle JTAG
signals.

Table 6 shows the overall current consumed by the MC72000 in many well-known scenarios as well as
detailed current in real-time specific modes.
The first row in Table 6 shows the maximum peak and typical average total current consumed by the
device in most scenarios used by PDAs, cell phone design, and other audio-capable devices such as
headsets. The current specified in this row is the total current consumed through the three power groups of
the MC72000 (i.e., the voltage relationship between the three different supply voltages in these three
groups are ignored). Power dissipated by the MC72000 may, therefore, be different than the direct power
consumption calculated on the total current consumption.
In order to find current values for special scenarios not covered by the typical values of total current
consumption, the current consumed in each of the three power groups are also defined in a variety of
usages. Each value represents the current consumed in between a repeatedly symmetrical timeframe, for
example, the BB power supply current for transmitting one-slot ACL packets is defined as the time from
start of TX burst to the start of RX burst, as the same current consumption is repeated again in the next TX
slot. This also applies to all currents defined for receiving packets regardless of packet type. See example
below in Figure 2. The repeatedly symmetrical pattern definition for the listed scenarios are shown in
Table 7.

NOTE:
Low power and small PCB footprints are critical for certain applications.
Therefore, input pins not used must be pulled high using internal pull-ups
to avoid floating nodes and the need for external pull-up resistors. Unused
pins may also be tied to an external appropriate logic voltage level (for
example, either VDD or GND). Weak pull-ups are available internally on
all IO and BB pins (100k ohms typical case), pull-downs are available on
RESET_BB, TCK, TRST_B pins. Internal level-shifters are used to
accommodate the difference between BB and IO voltages. This provides
glueless interface to peripherals.
4.1 Pin Assignment Listing
The following table (Table 9) shows the pin assignment listing for the MC72000 IC. The pins are
organized into functional groups.
• The Pin Name and Functionality columns show the actual name and a brief description of each pin,
with respect to the ball assignment in the column Ball #.
• The Power Group column lists the Supply Power Group assignment.
• The Pin Type column shows the type of internal circuitry to the chip.
• The Reset State column lists the pin input/output direction at chip RESET_BB.
• The Alternate Function column lists each of the GPIO port alternate input and output selections
available. Some selections are test- or development-mode specific.

4.2 Pin Descriptions
The following table provides detailed pin descriptions for the RF; clock, reset, and JTAG; Bluetooth; SSI
and UART; and UART, SPI1, and TIM including the GPIO shared package pins.
In the following table, the general-purpose input/output (GPIO) is designed to share package pins with
other peripheral modules on the chip. If the peripheral, which normally controls a given pin, is not
required, then the pin may be programmed to be a general-purpose input/output (GPIO) or alternate
function 2 with programmable pull-up. The GPIO module design has two available ports (Port B and Port
C). The individual control for each pin can be in normal functional mode, alternate function mode 2, or
GPIO mode. The individual direction control for each pin is in GPIO mode. The individual pull-up enable
control for each pin is in normal function mode, alternate function mode 2, or GPIO mode.
• Normal mode. The peripheral module controls the output enable and any output data to the pad and
any input data from the pad is passed to the peripheral.
• Alternate function 1 mode (GPIO). The GPIO module controls the output enable to the pad and
supplies any data to be output.
• Alternate function 2 mode. The peripheral module controls the output enable and any output data
to the pad and any input data from the pad is passed to the peripheral.

Not all power supply pins including ground pins are described in the following pin description list as all of
these pins share the same name within the three power groups. Refer to Section 10, “Applications
Information,” for details on how to isolate and identify the correct configuration for the power supply pins.
Table 15. Pin Descriptions
RF Signals
DCLF1
Data Clock Loop Filter charge pump output for external loop filter.
MNLF
XEMIT
XBASE
RFTEST+
Main Frac-N Loop Filter (Charge Pump). The external loop filter is referenced to VCC_RF in order
to minimize transmit phase noise.
Reference oscillator emitter. A bias current of 50 µA is supplied internally to the emitter. This pin
must be left open if external (not crystal) reference frequency is used.
Reference oscillator base. The base is the reference oscillator input. An on-chip capacitor trim
network is also included to allow the user to use relatively inexpensive crystals. This pin is also the
feed-point in case of using external (not crystal) reference frequency.
This pin is for factory use only. It must be left open.
RFTEST- This pin is for factory use only. It must be left open.
RFIN
PAOUT+
RFIN is the RF input to the LNA. The LNA is a bipolar cascode design. The input is the base of the
common emitter transistor. Minimum external matching is required to optimize the input return loss
and gain. The cascode output drives the primary of an on-chip balun single-ended.
Positive differential PA output. An external differential-to-single-ended matching network is desired.
PAOUT-
EPAEN
EPADRV
GPO
Negative differential PA output. An external differential-to-single-ended matching network is
desired.
External PA enable is a digital output which can be used to enable an external PA. It is normally
placed under sequence manager control. This output can also be used to control an external Rx/Tx
switch requiring complementary drive.
External PA driver DAC output. Analog output ranges from 0.02 to VCC_RF - 0.02. The EPADRV is
linearly scaled to a maximum VCC_RF of 3.1 V.
The General Purpose Output is a digital output. GPO is normally controlled by the internal
sequence manager but may also be programmable. This signal is typically used to control an
external Rx/Tx switch.
Baseband Clock, Reset, and JTAG Signals
EXTAL_BB
32.768 kHz baseband external crystal clock input. In case of using external clock, the signal must
be fed to this pin, while leaving XTAL pin open.
XTAL_BB
32.768 kHz baseband crystal clock output. This pin must be left open in case of using external
clock.
TDI
The test data input pin provides a serial input data stream to all TAP controllers. TDI is sampled on
the rising edge of TCK. Leave open if JTAG is unused.
TDO
The test data output pin is tri-statable, providing serial output data from the Master TAP or ARM
Core TAP controller. It is actively driven in the shift-IR and shift-DR controller states of the TAP
controller state machine. TDO changes on the falling edge of TCK.

TRST_B
TMS
This active low Schmitt trigger input pin provides an asynchronously reset signal to all TAP
controllers to initialize the test controller. Leave open or pull-down if JTAG is unused.
The test mode select input pin is used to sequence all TAP controllers. The TAP control module
and the TTS device port determine the TAP sequenced. TMS is sampled on the rising edge of
TCK. Leave open or pull-up if JTAG is unused.
TCK
The test clock input pin is used to synchronize the JTAG test logic. It provides the clock to
synchronize the test logic and shift serial data to and from all TAP controllers. Leave open if JTAG
is unused.
RTCK
The return test clock output pin returns the synchronization test clock to ARM development tools to
be entered from the serial debug input line.
The test tap select input pin directly controls the multiplexing logic to select between the chip TAP
TTS and the core TAP. A logic 1 applied to the tap select input will select the chip TAP. Leave open if
JTAG is unused.
MODE1
Test/boot mode select pins. In order to support a flexible development system, the system must be
able to boot from different memories during system reset and power-up. This pin can select two of
the four different memory maps, as MODE0 is hardwired internally. All the different boot modes
start reading data at address 0x0000_0000, since this is where the ARM7 reset vector is located.
RESET_BB
The reset in pin is an active low Schmitt trigger input that provides reset to the internal circuitry. The
RESET input will be qualified as valid if it will be asserted for at least three CLK cycles.

5.1.1 ARM7 Processor
The MC72000 Bluetooth Baseband Controller architecture is based on the 32-bit ARM7TDMI
microprocessor. It is an industry-standard processor recognized for its efficient MIPS/WATT benchmark,
along with excellent code efficiency when working in the 16-bit THUMB mode. The architecture is based
on RISC principles and supports two instruction sets:
• 32-bit ARM instruction set
• 16-bit THUMB instruction set
The ARM7 processor handles the high speed processing of data and link control management. The
MC72000 has 64 Kb RAM and 256 Kb ROM embedded containing a full Bluetooth baseband and upper
stacks. The ARM7 processor is primarily executing code from ROM and handles device initialization,
power control, protocol behavior, and packet formatting.

System Description
Freescale Semiconductor, Inc.
The program execution in the MC72000 Bluetooth Baseband Controller is predominantly ROM-based,
with internal RAM for data storage, application code, and ROM code patching. However, it is necessary to
download the application software and configuration data into RAM from an external interface. This is
done either as individual files when needed, as a complete image at power up containing all the files from
a host system, or from a low-cost serial EEPROM (four-wire connection) connected to the serial peripheral
interface (SPI).
5.1.2 Baseband Processor
The baseband processor digitally demodulates the signal at the output of the radio discriminator. Rather
than immediately making a threshold decision based on the amplitude of the signal, it analyzes the
waveform shape over more than one symbol before it makes a decision. This feature allows the Maximum
Likelihood Sequence Estimation and Joint Detection algorithms (JD/MLSE) to improve adjacent channel
rejection and signal acquisition. Without the joint detection and MLSE algorithms, it is possible to have
high sensitivity but low throughput because of false/missing acquisitions and high interference. Joint
detection provides simultaneous frequency and timing acquisition on the entire header rather than relying
on just the synchronization portion.
5.1.2.1 Bluetooth Link Controller
The Bluetooth link controller module (BTLC) handles all link controller specific functions.
Raw data can be read from/written to the module, and the BTLC takes care of transmission-related timing,
as well as data signal processing functions like encryption and cyclic redundancy check (CRC)/header
error correction (HEC) generation. Embedded in the BTLC are also the dedicated Bluetooth timers, which
maintain an accurate estimate of time in both the native and the remote module.
A small, dedicated Bluetooth serial peripheral interface controller handles all serial communication with
the radio part of the MC72000 Integrated Bluetooth Radio.
The functionality of the baseband will be elaborated on in Section 8, “Bluetooth Baseband Functionality
Overview.”
5.1.3 Bluetooth Radio
The design is based on Motorola's third-generation Bluetooth architecture that has set the industry standard
for interoperability, complete functionality, and compliance with the Bluetooth specification.
The radio portion of MC72000 exhibits superior RF performance with small size and low cost. A
minimum of external components are required to complete the RF link of a Bluetooth system, while
maintaining superior performance.
5.1.3.1 Receiver
The receiver is a 6 MHz low-IF frequency type using analog image cancellation. The LO is set to either
high-side or low-side injection so that the image will fall within the ISM band when the frequency to be
received is set to edge of the ISM band. The integrated Bluetooth baseband automatically decides the use
of high-side or low-side injection to the receiver, based on the active receive channel. The low-power
integrated LNA and BPF exhibits the excellent sensitivity and noise rejection performance, which is
further improved by the total system solution using the JD/MLSE baseband signal processing.

Freescale Semiconductor, Inc. System Description
5.1.3.2 Transmitter
The shape of the transmit pulse as required by the Bluetooth specification is controlled by a look-up table
that directly modulates the high frequency and accuracy main fractional VCO. The gain of the transmitter
is adjustable, and pin connections for controlling an external PA are provided for Class 1 operation. The
output of the PA is differential and, therefore, requires a balun that may be implemented in stripline or by
using a discrete balun. The GPO pin controls the external antenna switch, which is set automatically by the
internal sequence manager, and therefore requires no baseband interruption. As the transmitter section is a
direct launch transmitter operating directly at the transmit frequency, the out-of-band spurious emissions
are reduced to a minimum to comply with sensitive environments and strict requirements for other
applications like cell phones, PDAs, and computer accessories.
5.1.4 Clock and Reset Module
The clock and reset module (CRM) is dedicated to handling all clock, reset, and power management
features in the MC72000 Bluetooth Baseband Controller.
It ensures that the different clock and reset signals are stable before they are fed to the internal logic in the
MC72000 Bluetooth Baseband Controller. The CRM is designed to make full use of the facilities supplied
by the Bluetooth standard to conserve power, while still maintaining a Bluetooth link.
Two reference clocks are used to drive the MC72000: one for low power mode (32.768 kHz), and one for
accurate transmit, receive, and timing operation. Reference frequency can be chosen to cover a great
variety of typical reference frequencies used in cell phones, PDAs, and other equipment. This is due to an
internal data clock VCO ensuring that the ARM7 processor always runs at the correct frequency. The
internal crystal oscillator that feeds its clock to the data clock VCO and the radio portion covers the full
supply and temperature range with its very low-noise and trimable reference frequency based on an
external crystal. The oscillator may also be driven using an external reference clock from other
applications with minimum load to the external application.
The CRM module also includes a watchdog to safeguard against potential software failures.
5.1.5 High-Speed UART
The universal asynchronous receiver/transmitter (UART) module provides one of the main interfaces to
the MC72000 Bluetooth Baseband Controller. The generated baud rate is based on a configurable divisor
and input clock. The UART transmit and receive buffer sizes are 32 bytes each.
5.1.6 High-Speed CSPI
The MC72000 Bluetooth Baseband Controller contains one configurable serial peripheral interface (CSPI)
module, CSPI1. CSPI1 may be connected to a variety of SEEPROM and serial flash devices. They are
described in Section 10.8.7, “Possible EEPROM Types.”
The CSPI module is master/slave configurable, equipped with 16 byte data out buffers (transmit and
receive FIFOs), and allows the MC72000 Bluetooth Baseband Controller to interface with external CSPI
master or slave devices. It enables fast data communication with a fewer number of software interrupts by
incorporating the SPIRDY and SS control signals.

System Description
Freescale Semiconductor, Inc.
5.1.7 High-Speed SSI
The synchronous serial interface module (SSI) is a full-duplex serial port allowing digital signal processors
(DSPs) to communicate with a variety of serial devices, including industry-standard CODECs, other DSPs,
microprocessors, and peripherals. The SSI is typically used to transfer samples in a periodic manner and
consists of a variety of registers that handle port, status, control, transmit and receive, serial clock
generation, and frame synchronization.
5.1.8 Bluetooth Audio Signal Processor
High audio quality is of great importance to the end user. Section 10.9, “Audio,” describes the audio
features.
A dedicated Bluetooth audio signal-processing module (BTASP) has been designed to give users superior
audio performance. The BTASP module handles all filtering, interpolation, as well as encoding/decoding
with a minimum of processor intervention.
The internal voice-processing unit converts raw 16-bit PCM voice data and compressed voice data to
uncompressed voice. Compression modes are A-Law, µ-Law, and CVSD. It performs filtering and accepts
CODEC rates of 8, 16, 32, and 64 kbits/sec.
An external CODEC connected to the synchronous serial interface (SSI) is required for voice processing, if
needed.
5.1.9 Timer
The dual timer module (TMR) is a general purpose module, used for timing control and
application-specific tasks. The TMR can also be configured to perform pulse width modulation (PWM) or
put into a quadrature-count mode if needed. The TMR contains two identical 16-bit counter/timer groups,
each of which supports counting, prescaling, comparing, loading, capturing, and holding options.
5.1.10 General Purpose Input/Output
The MC72000 Bluetooth Baseband Controller supports a maximum of 16 GPIO lines grouped in two
ports. Port B contains 6 lines, Port C contains 10 lines. These ports can be configured as GPIO pins or
dedicated peripheral interface pins.
5.1.11 JTAG Test Interface Controller
The JTIC interface offers full JTAG and boundary scan capabilities for debug and production test
purposes, as well as access to the JTAG interface on the ARM.
