MC68HC812 General Description

IntroductionThe MC68HC812A4 microcontroller unit (MCU) is a 16-bit device composed of standard on-chip peripheral modules connected by an intermodule bus. Modules include:• 16-bit central processor unit (CPU12)• Lite integration module (LIM)• Two asynchronous serial communications interfaces (SCI0 and SCI1)• Serial peripheral interface (SPI)• Timer and pulse accumulator module• 8-bit analog-to-digital converter (ATD)• 1-Kbyte random-access memory (RAM)• 4-Kbyte electrically erasable, programmable read-only memory (EEPROM)• Memory expansion logic with chip selects, key wakeup ports, and a phase-locked loop (PLL)FeaturesFeatures of the MC68HC812A4 include:• Low-power, high-speed M68HC12 CPU• Power-saving stop and wait modes• Memory – 1024-byte RAM – 4096-byte EEPROM – On-chip memory mapping allows expansion to more than5-Mbyte address space• Single-wire Background Debug® mode• Non-multiplexed address and data buses• Seven programmable chip-selects with clock stretching (expanded modes)• 8-channel, enhanced 16-bit timer with programmable prescaler – All channels configurable as input capture or output compare – Flexible choice of clock source• 16-bit pulse accumulator• Real-time interrupt circuit• Computer operating properly (COP) watchdog• Clock monitor• Phase-locked loop (PLL)• Two enhanced asynchronous non-return-to-zero (NRZ) serial communication interfaces (SCI)• Enhanced synchronous serial peripheral interface (SPI)• 8-channel, 8-bit analog-to-digital converter (ATD)• Up to 24 key wakeup lines with interrupt capability• Available in 112-lead low-profile quad flat pack (LQFP) packaging
