MC68HC908GT16 Datasheet, PDF (36/412 Pages) Motorola, Inc – Microcontrollers

General Description
• Up to 36 general-purpose input/output (I/O) pins, including:
– 28 shared-function I/O pins
– Six or eight dedicated I/O pins, depending on package choice
• Selectable pullups on inputs only on ports A, C, and D. Selection
is on an individual port bit basis. During output mode, pullups are
disengaged.
• High current 10-mA sink/10-mA source capability on all port pins
• Higher current 20-mA sink/source capability on PTC0–PTC4
• Timebase module with clock prescaler circuitry for eight user
selectable periodic real-time interrupts with optional active clock
source during stop mode for periodic wakeup from stop using an
external 32-kHz crystal or internal oscillator
• User selection of having the oscillator enabled or disabled during
stop mode
• 8-bit keyboard wakeup port
• Available packages:
– 42-pin shrink dual in-line package (SDIP)
– 44-pin quad flat pack (QFP)
• Specific features of the MC68HC908GT16 in 42-pin SDIP are:
– Port C is only 5 bits: PTC0–PTC4
– Port D is 8 bits: PTD0–PTD7; dual 2-channel TIM modules
• Specific features of the MC68HC908GT16 in 44-pin QFP are:
– Port C is 7 bits: PTC0–PTC6
– Port D is 8 bits: PTD0–PTD7; dual 2-channel TIM modules
