NXP  MC908QY4ACDWE  微控制器, 8位, EEPROM 仿真器 Q, HC08Q, 8 MHz, 4 KB, 128 Byte, 16 引脚, SOIC

The is a 8-bit EEPROM Emulation Microcontroller based on high-performance M68HC08 CPU with CISC architecture operates at a maximum internal bus frequency of 8MHz. The device incorporates 4096byte internal flash, on-chip random-access memory RAM, 6-channel 10-bit A/D converter and 14 general-purpose I/O pins. This device also features peripherals like 2-channel 16-bit timer interface TIM module. This device is fully upward-compatible object code with M68HC05 family.
