General description D The LPC2921/2923/2925 combine an ARM968E-S CPU core with two integrated TCM blocks operating at frequencies of up to 125 MHz, Full-speed USB 2.0 device controller, CAN and LIN, up to 40 kB SRAM, up to 512 kB flash memory, two 10-bit ADCs, and multiple serial and parallel interfaces in a single chip targeted at consumer, industrial, medical, communication, and automotive markets. To optimize system power consumption, the LPC2921/2923/2925 has a very flexible Clock Generation Unit (CGU) that provides dynamic clock gating and scaling. D R A FT D R A 2. Features „ ARM968E-S processor running at frequencies of up to 125 MHz maximum. „ Multilayer AHB system bus at 125 MHz with four separate layers. „ On-chip memory: ‹ Two Tightly Coupled Memories (TCM), 16 kB Instruction (ITCM) and 16 kB Data TCM (DTCM). ‹ On the LPC2925, two separate internal Static RAM (SRAM) instances, 16 kB each. ‹ On the LPC2923 and LPC2921, one 16 kB SRAM block. ‹ 8 kB ETB SRAM, also usable for code execution and data. ‹ Up to 512 kB high-speed flash-program memory. ‹ 16 kB true EEPROM, byte-erasable/programmable. „ Dual-master, eight-channel GPDMA controller on the AHB m...
