LPC1311FHN33: Entry-level 32-bit Microcontroller (MCU) based on Arm^® Cortex^®-M3 Core

Overview

The LPC1311FHN33 is an Arm Cortex-M3-based microcontroller for embedded applications featuring a high level of integration and low power consumption. The LPC1311FHN33 operates at CPU frequencies of up to 72 MHz. The peripheral complement of the LPC1311FHN33 includes up to 8 kB of flash memory, up to 2 kB of data memory, one Fast-mode plus (Fm+) I2C interface, one UART, four general purpose timers, and up to 28 general purpose I/O pins.
