General description

The LPC18S50/S30/S10 are ARM Cortex-M3 based microcontrollers with security

features for embedded applications. The ARM Cortex-M3 is a next generation core that

offers system enhancements such as low power consumption, enhanced debug features,

and a high level of support block integration.

The LPC18S50/S30/S10 operate at CPU frequencies of up to 180 MHz. The ARM

Cortex-M3 CPU incorporates a 3-stage pipeline and uses a Harvard architecture with

separate local instruction and data buses as well as a third bus for peripherals. The ARM

Cortex-M3 CPU also includes an internal prefetch unit that supports speculative

branching.

The LPC18S50/S30/S10 include up to 200 kB of on-chip SRAM, security features with

AES engine, a quad SPI Flash Interface (SPIFI), a State Configurable Timer/PWM

(SCTimer/PWM) subsystem, two High-speed USB controllers, Ethernet, LCD, an external

memory controller, and multiple digital and analog peripherals.

See Section 17 “References” for additional documentation.
