MC68HC908GR16 Datasheet, PDF (20/310 Pages) Motorola, Inc – Microcontrollers

General Description
Freescale Semiconductor, Inc.
• Low-power design; fully static with stop and wait modes
• Standard low-power modes of operation:
– Wait mode
– Stop mode
• Master reset pin and power-on reset (POR)
• 16 Kbytes of on-chip 100k cycle write/erase capable FLASH memory
• 1 Kbyte of on-chip random-access memory (RAM)
• 406 bytes of FLASH programming routines read-only memory (ROM)
• Serial peripheral interface (SPI) module
• Enhanced serial communications interface (ESCI) module
• Two 16-bit timer interface modules (2-channel TIM1 and 2-channel TIM2)
with selectable input capture, output compare, and pulse-width modulation
(PWM) capability on each channel
• 8-channel, 10-bit successive approximation analog-to-digital converter
(ADC)
• BREAK (BRK) module to allow single breakpoint setting during in-circuit
debugging
• Internal pullups on IRQ and RST to reduce customer system cost
• Up to 37 general-purpose input/output (I/O) pins, including:
– 28 shared-function I/O pins
– Up to nine 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/source capability on all port pins
• Higher current 20-mA sink/source capability on PTC0–PTC4
• 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
• 8-bit keyboard wakeup port
• 5 mA maximum current injection on all port pins to maintain input protection
• Available packages:
– 32-pin LQFP
– 48-pin low-profile quad flag pack (LQFP)
