Product data sheet

1. General description

The LPC43S5x/S3x are ARM Cortex-M4 based microcontrollers 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, security features with AES engine,

a quad SPI Flash Interface (SPIFI), 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 LPC43S5x/S3x 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 unit is integrated in the core. The ARM Cortex-M4 with

floating-point unit is often referred to as M4F.

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. 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.

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