MC68C812A4 3.3V Electrical Characteristics
The MC68C812A4 is the low-voltage version of the standard MC68HC812A4 microcontroller unit
(MCU), 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).
