Description
LPC3141/3143
Low-cost, low-power ARM926EJ microcontrollers with USB High-speed OTG, SD/MMC, and NAND flash controller
Rev. 1 — 4 June 2012 Product data sheet
1. General description
The NXP LPC3141/3143 combine a 270 MHz ARM926EJ-S CPU core, High-speed USB 2.0 OTG, 192 KB SRAM, NAND flash controller, flexible external bus interface, four channel 10-bit A/D, and a myriad of serial and parallel interfaces in a single chip targeted at consumer, industrial, medical, and communication markets. To optimize system power consumption, the LPC3141/3143 have multiple power domains and a very flexible Clock Generation Unit (CGU) that provides dynamic clock gating and scaling.
