NXP Semiconductors LPC1800 32位ARM Cortex™-M3 MCU

NXP Semiconductors LPC1800系列32位元ARM Cortex™-M3微控制器是業界速度最快的Cortex-M3 MCU，處理器頻率高達180MHz。LPC1800 MCU採用與LPC4300系列Cortex-M4 MCU相同的超低漏電90-nm技術製成，並與眾多相同的關鍵功能具有引腳和軟體相容性。NXP LPC1830和LPC1850 MCU的特點包括進階周邊設備，例如乙太網絡、高速USB 2.0主機端/OTG/裝置、LCD控制器和CAN 2.0B。還有兩個新的創新型周邊設備：柔性Quad-SPI接口和一個狀態可配置計時器子系統。LPC1800裝置可提供高達1MB的靈活雙存儲庫閃存，適用於高可靠性應用內重編程和無間歇閃存運行。NXP LPC1830和LPC1850 MCU包括透過多個存儲庫提供的高達200 kB的晶片上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.
