Product Details

Description

Features:

• High-performance M68HC08 architecture optimized for C-compilers

• 8-MHz internal bus frequency
• Clock generation module supporting 1-MHz to 8-MHz crystals
• FLASH program memory security⁽¹⁾• On-chip programming firmware for use with host personal computer which does not require high voltage for entry
• In-system programming (ISP)
• System protection features:
Optional computer operating properly (COP) reset
Low-voltage detection with optional reset and selectable trip points for 3.3-V and 5.0-V operation
Illegal opcode detection with reset
Illegal address detection with reset
• 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)
• On-chip FLASH memory:
MC68HC908GR60A - 60 Kbytes

• 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 PTC0PTC4 and PTF0PTF3
• 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
