NXP  LPC1837FET256,551  微控制器, 32位, ARM 皮质-M3, 180 MHz, 1 MB, 136 KB, 256 引脚, LBGA

The is a 32-bit Microcontroller based on ARM Cortex-M3 core with RISC architecture operates at a maximum frequency of 180MHz. 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 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 device incorporates 1MB internal flash, 136kB internal RAM, 16kB EEPROM, a quad SPI Flash Interface SPIFI, a State-configurable Timer/PWM SCTimer/PWM subsystem, two high-speed USB controllers, Ethernet, an external memory controller and multiple digital and analog peripherals and 164 general-purpose I/O pins.
