The LPC185x/3x/2x/1x 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 LPC185x/3x/2x/1x 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 LPC185x/3x/2x/1x include up to 1 MB of flash and 136 kB of on-chip SRAM， 16 kB of
EEPROM memory， 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.
