Introduction
The MC68HC08AZ32A is a member of the low-cost, high-performance M68HC08 Family of 8-bit microcontroller units (MCUs). All MCUs in the Family use the enhanced  M68HC08 central processor unit (CPU08) and are available with a variety of modules, memory sizes and types, and package types.

Features
Features include the following:
• High-performance M68HC08 architecture
• Fully upward-compatible object code with M6805, M146805, and M68HC05 Families
• 8.4-MHz internal bus frequency at 125°C
• MSCAN08 controller (scalable CAN) (implementing CAN 2.0b protocol as defined in BOSCH specification September, 1991)
• Available in 64-pin quad flat pack (QFP)
• 32,256 bytes user read-only memory (ROM)
• User ROM data security(1)
• 512 bytes of on-chip electrically erasable programmable read-only memory (EEPROM) with security feature
• 1 Kbyte of on-chip random-access memory (RAM)
• Serial peripheral interface (SPI) module
• Serial communications interface (SCI) module
• 16-bit timer interface module (TIMA) with six input capture/output compare channels
• 16-bit timer interface module (TIMB) with two input capture/output compare channels
• Programmable interrupt timer (PIT)
• Clock generator module (CGM)
• 8-bit, 15-channel analog-to-digital convertor (ADC)
• 5-bit keyboard interrupt module (KBI)
• System protection features:
– Computer operating properly (COP) with optional reset
– Low-voltage detection with optional reset
– Illegal opcode detection with optional reset
– Illegal address detection with optional reset
• Low-power design (fully static with stop and wait modes)
• Master reset pin and power-on reset (POR)
Features of the CPU08 include:
• Enhanced HC05 programming model
• Extensive loop control functions
• 16 addressing modes (eight more than the HC05)
• 16-bit index register and stack pointer
• Memory-to-memory data transfers
• Fast 8 × 8 multiply instruction
• Fast 16/8 divide instruction
• Binary-coded decimal (BCD) instructions
• Optimization for controller applications
• C language support
