MC908GZ60CFUE Datasheet, PDF (24/352 Pages) Freescale Semiconductor, Inc – Standard features, Features of the CPU08

General Description
• Standard low-power modes of operation:
– Wait mode
– Stop mode
• Master reset pin and power-on reset (POR)
• On-chip FLASH memory:
– MC68HC908GZ60 — 60 Kbytes
– MC68HC908GZ48 — 48 Kbytes
– MC68HC908GZ32 — 32 Kbytes
• Random-access memory (RAM):
– MC68HC908GZ60 — 2048 bytes
– MC68HC908GZ48 — 1536 bytes
– MC68HC908GZ32 — 1536 bytes
• Serial peripheral interface (SPI) module
• Enhanced serial communications interface (ESCI) module
• One 16-bit, 2-channel timer interface module (TIM1) with selectable input capture, output compare,
and pulse-width modulation (PWM) capability on each channel
• One 16-bit, 6-channel timer interface module (TIM2) with selectable input capture, output compare,
and pulse-width modulation (PWM) capability on each channel
• 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 crystal
• 24-channel, 10-bit successive approximation analog-to-digital converter (ADC)
• 8-bit keyboard wakeup port with software selectable rising or falling edge detect, as well as high or
low level detection
• Up to 53 general-purpose input/output (I/O) pins, including:
– 40 shared-function I/O pins, depending on package choice
– Up to 13 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.
• Internal pullups on IRQ and RST to reduce customer system cost
• High current 10-mA sink/source capability on all port pins
• Higher current 20-mA sink/source capability on PTC0–PTC4 and PTF0–PTF3
• User selectable clockout feature with divide by 1, 2, and 4 of the bus or crystal frequency
• User selection of having the oscillator enabled or disabled during stop mode
• BREAK module (BRK) to allow single breakpoint setting during
in-circuit debugging
• Available packages:
– 32-pin low-profile quad flat pack (LQFP)
– 48-pin low-profile quad flat pack (LQFP)
– 64-pin quad flat pack (QFP)
• Specific features in 32-pin LQFP are:
– Port A is only 4 bits: PTA0–PTA3; shared with ADC and KBI modules
– Port B is only 6 bits: PTB0–PTB5; shared with ADC module
– Port C is only 2 bits: PTC0–PTC1; shared with MSCAN module
– Port D is only 7 bits: PTD0–PTD6; shared with SPI, TIM1 and TIM2 modules
– Port E is only 2 bits: PTE0–PTE1; shared with ESCI module
