General Description
Introduction
The MC68HC908QY4A 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:
• High-performance M68HC08 CPU core

• 5-V and 3-V operating voltages (VDD)
• 8-MHz internal bus operation at 5 V, 4-MHz at 3 V
• Trimmable internal oscillator
– Software selectable 1 MHz, 2 MHz, or 3.2 MHz internal bus operation
– 8-bit trim capability
– ±25 untrimmed
– Trimmable to approximately 0.4(1)
• Software selectable crystal oscillator range, 32–100 kHz, 1–8 MHz and 8–32 MHz
• Software configurable input clock from either internal or external source
• Auto wakeup from STOP capability using dedicated internal 32-kHz RC or bus clock source
• On-chip in-application programmable FLASH memory
– Internal program/erase voltage generation
– Monitor ROM containing user callable program/erase routines
– FLASH security(2)
• On-chip random-access memory (RAM)
• 2-channel, 16-bit timer interface (TIM) module
• 6-channel, 10-bit analog-to-digital converter (ADC) with internal bandgap reference channel (ADC10)
• Up to 13 bidirectional input/output (I/O) lines and one input only:
– Six shared with KBI
– Six shared with ADC
– Two shared with TIM
– One input only shared with IRQ
– High current sink/source capability on all port pins
– Selectable pullups on all ports, selectable on an individual bit basis
– Three-state ability on all port pins
• 6-bit keyboard interrupt with wakeup feature (KBI)
– Programmable for rising/falling or high/low level detect
• Low-voltage inhibit (LVI) module features:
– Software selectable trip point
• System protection features:
– Computer operating properly (COP) watchdog
– Low-voltage detection with reset
– Illegal opcode detection with reset
– Illegal address detection with reset
• External asynchronous interrupt pin with internal pullup (IRQ) shared with general-purpose input pin
• Master asynchronous reset pin with internal pullup (RST) shared with general-purpose input/output (I/O) pin
• Memory mapped I/O registers
• Power saving stop and wait modes
