LPC2220FBD144

NXP  LPC2220FBD144  微控制器, 32位, ARM7TDMI, 75 MHz, 64 KB, 144 引脚, LQFP

The is a flashless 16-/32-bit Microcontroller based on ARM7TDMI-S CPU with real-time emulation and embedded trace support. For critical code size applications, the alternative 16-bit Thumb mode reduces code by more than 30 % with minimal performance penalty. The device incorporates 16kB on-chip SRAM, 8-channel 10-bit A/D converter, three 32-bit timers, PWM channels, up to nine external interrupt pins and 76 general-purpose I/O pins.
