General Description
⢠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:
â Six shared with KBI
â Six shared with ADC
â Two shared with TIM
â One input only shared with IRQ
â High current sink/source capability on all port pins
â Selectable pullups on all ports, selectable on an individual bit basis
â Three-state ability on all port pins
⢠6-bit keyboard interrupt with wakeup feature (KBI)
â Programmable for rising/falling or high/low level detect
⢠Low-voltage inhibit (LVI) module features:
â Software selectable trip point
⢠System protection features:
â Computer operating properly (COP) watchdog
â Low-voltage detection with reset
â Illegal opcode detection with reset
â 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
⢠MC68HC908QY4A, MC68HC908QY2A and MC68HC908QY1A are available in these packages:
â 16-pin plastic dual in-line package (PDIP)
