Master reset pin and power-on reset (POR)
7680 bytes of on-chip FLASH memory on the MC68HC908GR8A and 4096 byes of on-chip FLASH
memory on the MC68HC908GR4A with in-circuit programming capabilities of FLASH program
memory.
384 bytes of on-chip random-access memory (RAM)
544 bytes of FLASH programming routines read-only memory (ROM)
Serial peripheral interface (SPI) module
Serial communications interface (SCI) module
One 16-bit, 2-channel timer (TIM1) and one 16-bit, 1-channel timer (TIM2) interface modules with
selectable input capture, output compare, and pulse-width modulation (PWM) capability on each
channel
Up to 6-channel, 8-bit successive approximation analog-to-digital converter (ADC) depending on
package choice
BREAK (BRK) module to allow single breakpoint setting during in-circuit debugging
Internal pullups on IRQ and RST to reduce system cost
Up to 21 general-purpose input/output (I/O) pins
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/source capability on all port pins
Higher current 15-mA sink/source capability on PTC0–PTC1
Timebase module (TBM) 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 crystal
User selection of having the oscillator enabled or disabled during stop mode
4-bit keyboard wakeup port
