two High-speed USB, LCD, and external memory controller
Rev. 6.1 — 7 February 2013
Product data sheet
1. 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.
