NXP Semiconductors LPC1800 32位ARM Cortex™-M3 MCU

NXP Semiconductors LPC1800系列32位ARM Cortex™-M3微控制器是业界最快的Cortex-M3 MCU，其处理器频率最高达180MHz。LPC1800 MCU是采用与LPC4300系列Cortex-M4 MCU相同的90nm超低泄漏技术精制而成，引脚和软件也同样与很多关键功能兼容。NXP LPC1830和LPC1850 MCU具有先进的外设，如以太网、高速USB 2.0主机/OTG/设备、LCD控制器和CAN 2.0B。还有两种创新外设：灵活的四路SPI接口和状态可配置计时器子系统。LPC1800器件可提供高达1MB的灵活双组闪存，以使应用内的重新编程和不间断闪存运行具备高可靠性。NXP LPC1830和LPC1850 MCU以多组的形式提供高达200kB的片上SRAM。

NXP LPC1857 is a high-performance, cost-effective Cortex™-M3 microcontroller featuring 1MB of flash memory, 136kB of SRAM, and advanced peripherals, including Ethernet, High Speed USB 2.0 Host/OTG/Device, LCD controller, and CAN 2.0B. NXP LPC1857 operates at speeds up to 180MHz and also features two new configurable peripherals: an SPI Flash Interface and a State Configurable Timer. All members of the LPC1800 series include a Wakeup Interrupt Controller, allowing automatic wake from any priority interrupt. These MCUs also feature four reduced power modes: Sleep, Deep-Sleep, Power-Down, and Deep Power-Down.
