1.0 GENERAL DESCRIPTION
The PIC12C67X devices are low-cost, high-perfor-
mance, CMOS, fully-static, 8-bit microcontrollers with
integrated analog-to-digital (A/D) converter and
EEPROM data memory (EEPROM on PIC12CE67X
versions only).
All PICmicro® microcontrollers employ an advanced
RISC architecture. The PIC12C67X microcontrollers
have enhanced core features, eight-level deep stack,
and multiple internal and external interrupt sources.
The separate instruction and data buses of the Harvard
architecture allow a 14-bit wide instruction word with
the separate 8-bit wide data. The two stage instruction
pipeline allows all instructions to execute in a single
cycle, except for program branches, which require two
cycles. A total of 35 instructions (reduced instruction
set) are available. Additionally, a large register set gives
some of the architectural innovations used to achieve a
very high performance.
PIC12C67X microcontrollers typically achieve a 2:1
code compression and a 4:1 speed improvement over
other 8-bit microcontrollers in their class.
The PIC12C67X devices have 128 bytes of RAM, 16
bytes of EEPROM data memory (PIC12CE67X only), 5
I/O pins and 1 input pin. In addition a timer/counter is
available. Also a 4-channel, high-speed, 8-bit A/D is
provided. The 8-bit resolution is ideally suited for appli-
cations requiring low-cost analog interface, (i.e.,
thermostat control, pressure sensing, etc.)
The PIC12C67X devices have special features to
reduce external components, thus reducing cost,
enhancing system reliability and reducing power con-
sumption. The Power-On Reset (POR), Power-up
Timer (PWRT), and Oscillator Start-up Timer (OST)
eliminate the need for external reset circuitry. There are
five oscillator configurations to choose from, including
INTRC precision internal oscillator mode and the
power-saving LP (Low Power) oscillator mode. Power-
saving SLEEP mode, Watchdog Timer and code
protection features improve system cost, power and
reliability. The SLEEP (power-down) feature provides a
power-saving mode. The user can wake-up the chip
from SLEEP through several external and internal
interrupts and resets.
PIC12C67X
A highly reliable Watchdog Timer with its own on-chip
RC oscillator provides protection against software
lock-up.
A UV erasable windowed package version is ideal for
code development, while the cost-effective One-Time-
Programmable (OTP) version is suitable for production
in any volume. The customer can take full advantage of
Microchip’s price leadership in OTP microcontrollers,
while benefiting from the OTP’s flexibility.
1.1 Applications
The PIC12C67X series fits perfectly in applications
ranging from personal care appliances and security
systems to low-power remote transmitters/receivers.
The EPROM technology makes customizing applica-
tion programs (transmitter codes, appliance settings,
receiver frequencies, etc.) extremely fast and conve-
nient, while the EEPROM data memory (PIC12CE67X
only) technology allows for the changing of calibration
factors and security codes. The small footprint pack-
ages, for through hole or surface mounting, make this
microcontroller series perfect for applications with
space limitations. Low-cost, low-power, high perfor-
mance, ease of use and I/O flexibility make the
PIC12C67X series very versatile even in areas where
no microcontroller use has been considered before
(i.e., timer functions, replacement of "glue" logic and
PLD’s in larger systems, coprocessor applications).
1.2 Family and Upward Compatibility
The PIC12C67X products are compatible with other
members of the 14-bit PIC16CXXX families.
1.3 Development Support
The PIC12C67X devices are supported by a full-
featured macro assembler, a software simulator, an in-
circuit emulator, a low-cost development programmer
and a full-featured programmer. A “C” compiler and
fuzzy logic support tools are also available.
