LPC185x,LPX181x,LPC182x規格書

　　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.
