LPC4350/30/20/10

32-bit ARM Cortex-M4/M0 MCU; up to 264 kB SRAM; Ethernet;

two High-speed USBs; advanced configurable peripherals

Rev. 2.1 — 23 September 2011

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 180 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 180 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 180 MHz.

• C_CAN1 added.

• Pin multiplexing increased to up to 9 levels.

• GPIO block updated.

• Pads updated.

2. Features and benefits
