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 150 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 data memory, a quad SPI
Flash Interface (SPIFI), a State Configuration Timer (SCT) subsystem, two High-speed
USB controllers, Ethernet, LCD, an external memory controller, and multiple digital and
analog peripherals.
