32-bit ARM Cortex-M4/M0 MCU; up to 264 kB SRAM; Ethernet;
two High-speed USBs; advanced configurable peripherals
Rev. 3.1 — 5 January 2012
Objective data sheet
1. General description
The LPC4350/30/20/10 are ARM Cortex-M4 based microcontrollers for embedded
applications which include an ARM Cortex-M0 coprocessor, up to 264 kB of SRAM,
advanced configurable peripherals such as the State Configurable Timer (SCT) and the
Serial General Purpose I/O (SGPIO) interface, two High-speed USB controllers, Ethernet,
LCD, an external memory controller, and multiple digital and analog peripherals. The
LPC4350/30/20/10 operate at CPU frequencies of up to 204 MHz.
The ARM Cortex-M4 is a next generation 32-bit core that offers system enhancements
such as low power consumption, enhanced debug features, and a high level of support
block integration. The ARM Cortex-M4 CPU incorporates a 3-stage pipeline, uses a
Harvard architecture with separate local instruction and data buses as well as a third bus
for peripherals, and includes an internal prefetch unit that supports speculative branching.
The ARM Cortex-M4 supports single-cycle digital signal processing and SIMD
instructions. A hardware floating-point processor is integrated in the core.
The ARM Cortex-M0 coprocessor is an energy-efficient and easy-to-use 32-bit core which
is code- and tool-compatible with the Cortex-M4 core. The Cortex-M0 coprocessor,
designed as a replacement for existing 8/16-bit microcontrollers, offers up to 204 MHz
performance with a simple instruction set and reduced code size.
Remark: This data sheet describes the Rev ‘A’ versions of parts LPC4350/30/20/10.
Compared to previous versions, the following updates apply:
Operating frequency increased to 204 MHz.
C_CAN1 added.
Pin multiplexing increased to up to 9 levels.
GPIO block updated.
Pads updated.
