The NXP LPC3131 combine an 180 MHz ARM926EJ-S CPU core, high-speed USB 2.0 On-The-Go (OTG), up to 192 KB SRAM, NAND flash controller, flexible external bus interface, four channel 10-bit ADC, 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 LPC3130/3131 have multiple power domains and a very flexible Clock Generation Unit (CGU) that provides dynamic clock gating and scaling.
