Part Number : MC68HC812A4
Function : 16-bit Microcontroller / The MC68HC812A4 microcontroller unit (MCU)
Maker : Motorola , Freescale
Pinouts : 
Description :
The MC68HC812A4 microcontroller unit (MCU) is a 16-bit device composed of standard on-chip peripheral modules connected by an intermodule bus.
Modules include a 16-bit central processing unit(CPU12), a Lite integration module (LIM), two asynchronous serial communications interfaces (SCI0 and SCI1), a serial peripheral interface (SPI), a timer and pulse accumulation module, an 8-bit analog to-digital converter (ATD), 1-Kbyte RAM, 4-Kbyte EEPROM, and memory expansion logic with chip selects, key wakeup ports, and a phase-locked loop (PLL).
Features :
1. Single-Wire Background Debug Mode
2. Non-Multiplexed Address and Data Buses
3. Seven Programmable Chip Selects with Clock Stretching (Expanded Modes)
4. 8-Channel, Enhanced 16-Bit Timer with Programmable Prescaler
