LPC2364, LPC2366, LPC2368, and LPC2378 device highlight

Introduction

Key Features:

  • 32-Bit ARM7® Core Architecture
  • 72MHz operation (64 Dhrystone MIPs)
  • Up to 512kB on-chip Flash and 58kB SRAM
  • Ethernet 10/100 MAC with DMA
  • USB 2.0 full-speed device with PHY and DMA
  • CAN 2.0B with two channels
  • General-purpose DMA controller
  • I2S, three I2C, three SPI/SSP, and four UARTs
  • 4MHz internal RC (IRC) oscillator trimmed to 1% accuracy
The LPC23xx series operates at 72MHz with up to 512KB of zero-wait state on-chip flash. More significant is its ability to simultaneously run the application, USB FS, CAN, and Ethernet. This is mainly achieved by the industry's only 2 AHB bus architecture in an ARM7-based MCU.
