Product data sheet

1. General description

The LPC435X_3X_2X_1X are ARM Cortex-M4 based microcontrollers with Floating Point

Unit (FPU) for embedded applications which include an ARM Cortex-M0 coprocessor, up

to 1 MB of flash and 136 kB of on-chip SRAM, 16 kB of EEPROM memory, two

high-speed USB controllers, Ethernet, LCD, an external memory controller, a quad SPI

Flash Interface (SPIFI) that supports execute-in-place, advanced configurable peripherals

such as the State Configurable Timer (SCTimer/PWM) and the Serial General Purpose

I/O (SGPIO) interface, and multiple digital and analog peripherals. The

LPC435X_3X_2X_1X operate at CPU frequencies of up to 204 MHz.

The ARM Cortex-M4 is a 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 into the core.

The ARM Cortex-M0 coprocessor is an energy-efficient and easy-to-use 32-bit core,

which is upward code- and tool-compatible with the Cortex-M4 core. It is ideal for handling

control or peripheral handling to free up the Cortex-M4 for real-time processing. The

Cortex-M0 coprocessor offers up to 204 MHz performance with a simple instruction set

and reduced code size. In LPC43xx, the Cortex-M0 coprocessor hardware multiply is

implemented as a 32-cycle iterative multiplier.

For additional documentation related to the LPC43xx parts, see Section 17.
