MC68HC908GZ8 Datasheet, PDF (22/344 Pages) Motorola, Inc – Microcontrollers

Freescale Semiconductor, Inc.
General Description
• 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)
• 8 Kbytes of on-chip 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
• Fine adjust baud rate prescalers for precise control of baud rate
• Arbiter module:
– Measurement of received bit timings for baud rate recovery without use
of external timer
– Bitwise arbitration for arbitrated UART communications
• LIN specific enhanced features:
– Generation of LIN 1.2 break symbols without extra software steps on
each message
– Break detection filtering to prevent false interrupts
• Two 16-bit, 2-channel timer interface modules (TIM1 and 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
• 2 mA maximum current injection on all port pins to maintain input protection
