The MC68HC08GP16A is members of the low-cost, high-performance M68HC08 Family of 8-bit microcontroller units (MCUs). All MCUs in the family use the enhanced M68HC08 central processor unit (CPU08) and are available with a variety of modules, memory sizes and types, and package types.
- High-performance M68HC08 architecture optimized for C-compilers
- Fully upward-compatible object code with M6805, M146805, and M68HC05 Families
- 8-MHz internal bus frequency
- System protection features:
- Optional computer operating properly (COP) reset
- Low-voltage detection with optional reset and selectable trip points for 3.0-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 read-only memory (ROM)
- MC68HC08GP16A — 15,872 bytes
- 512 bytes of on-chip random-access memory (RAM)
- Serial peripheral interface module (SPI)
- Serial communications interface module (SCI)
- Two 16-bit, 2-channel timer interface modules (TIM1 and TIM2) with selectable input capture, output compare, and PWM capability on each channel
- 8-channel, 8-bit successive approximation analog-to-digital converter (ADC)
- BREAK module (BRK) to allow single breakpoint setting during in-circuit debugging
- Internal pullups on IRQ and RST to reduce customer system cost
- Clock generator module with on-chip 32-kHz crystal compatible PLL (phase-lock loop)
- Up to 33 general-purpose input/output (I/O) pins, including:
- 26 shared-function I/O pins
- Five or seven 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/10-mA source capability on all port pins
- Higher current 15-mA sink/source capability on PTC0–PTC4
- 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 32-kHz crystal
- 8-bit keyboard wakeup port
- 5-mA maximum current injection on all port pins to maintain input protection
- Available packages: 42-pin shrink dual-in-line package (SDIP) and 44-pin quad flat pack (QFP)
- Specific features of the 42-pin SDIP
- Port C is only 5 bits: PTC0–PTC4
- Specific features of the 44-pin QFP
- Port C is 7 bits: PTC0–PTC6
