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, and memory expansion logic with chip selects, key wakeup ports, and a phase-locked loop (PLL).
- 1024-Byte RAM
- 4096-Byte Electrically Erasable Programmable Read-OnlyMemory (EEPROM)
- On-Chip Memory Mapping Allows Expansion to over 5-MbyteAddress Space
- All Channels Configurable as Input Capture or OutputCompare
- Flexible Choice of Clock Source
