General description

The LPC1850/30/20/10 are ARM Cortex-M3 based microcontrollers 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 LPC1850/30/20/10 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 LPC1850/30/20/10 include up to 200 kB of on-chip SRAM, a quad SPI Flash

Interface (SPIFI), a State Configurable Timer (SCT) subsystem, two High-speed USB

controllers, Ethernet, LCD, an external memory controller, and multiple digital and analog

peripherals.

Remark: This data sheet describes the Rev ‘-’ and the Rev ‘A’ versions of parts

LPC1850/30/20/10.
