LPC1857FET256,551

The LPC1857FET256 is a high-performance, cost-effective Cortex-M3 microcontroller featuring 1 MB of flash memory, 136 kB of SRAM, and advanced peripherals including Ethernet, High Speed USB 2.0 Host/OTG/Device, LCD controller, and CAN 2.0B. Operating at speeds up to 180 MHz, the LPC1857 also features two new configurable peripherals: a SPI Flash Interface and a State Configurable Timer. All members of the series include a Wakeup Interrupt Controller allowing automatic wake from any priority interrupt as well as four reduced power modes: Sleep, Deep-Sleep, Power-Down, and Deep Power-Down.
