1.General descriptionThe LPC185x/3x/2x/1x are ARM Cortex-M3 based microcontrollers for embeddedapplications. The ARM Cortex-M3 is a next generation core that offers systemenhancements such as low power consumption, enhanced debug features, and a highlevel of support block integration.The LPC185x/3x/2x/1x operate at CPU frequencies of up to 180 MHz. The ARMCortex-M3 CPU incorporates a 3-stage pipeline and uses a Harvard architecture withseparate local instruction and data buses as well as a third bus for peripherals. The ARMCortex-M3 CPU also includes an internal prefetch unit that supports speculativebranching.The LPC185x/3x/2x/1x include up to 1 MB of flash and 136 kB of on-chip SRAM, 16 kB ofEEPROM memory, a quad SPI Flash Interface (SPIFI), a State-configurable Timer/PWM(SCTimer/PWM) subsystem, two High-speed USB controllers, Ethernet, LCD, an externalmemory controller, and multiple digital and analog peripherals.For additional documentation related to the LPC18xx parts, see Section 17 “References”.2.Features and benefits Processor core ARM Cortex-M3 processor (version r2p1), running at CPU frequencies of up to180 MHz.
