LPC1347FBD64

NXP  LPC1347FBD64  微控制器, 32位, ARM 皮质-M3, 72 MHz, 64 KB, 10 KB, 64 引脚, LQFP

The is a 32-bit Microcontroller based on ARM Cortex-M3 core with RISC architecture operates at a maximum frequency of 72MHz. The ARM Cortex-M3 is a next generation core that offers system enhancements such as enhanced debug features and a higher level of support block integration. The ARM Cortex-M3 CPU incorporates a 3-stage pipeline and uses a Harvard architecture with separate local instruction and data buses as well as a third bus for peripherals. The ARM Cortex-M3 CPU also includes an internal prefetch unit that supports speculative branching. The device incorporates 68kB internal flash, 8kB internal RAM, 8-channel 10-bit A/D converter and 51 general-purpose I/O pins.
