LPC1820FBD144: High Performance 32-bit Microcontroller based on Arm^® Cortex^®-M3

Overview

The LPC1820FBD144 is a high-performance, cost-effective Cortex-M3 microcontroller featuring 168 kB of SRAM, and advanced peripherals including High Speed USB 2.0 Host/OTG/Device and CAN 2.0B. Operating at speeds up to 180 MHz, the LPC1820 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.
