The LPC2929FBD144,551 is an ARM9 microcontroller based on ARM968E-S CPU core with two integrated TCM blocks operating at frequencies of up to 125MHz. The device incorporates full-speed USB 2.0 OTG and device controller, CAN and LIN, 56kB SRAM, up to 768kB flash memory, external memory interface, three 10-bit ADCs and multiple serial and parallel interfaces in a single. To optimize system power consumption the device has a very flexible clock generation unit (CGU) that provides dynamic clock gating and scaling.
