MC68HC08GP32A Datasheet, PDF (20/258 Pages) Freescale Semiconductor, Inc – Microcontrollers

General Description
• 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
1.3.1 Features of the CPU08
Features of the CPU08 include:
• Enhanced HC05 programming model
• Extensive loop control functions
• 16 addressing modes (eight more than the HC05)
• 16-bit index register and stack pointer
• Memory-to-memory data transfers
• Fast 8 × 8 multiply instruction
• Fast 16/8 divide instruction
• Binary-coded decimal (BCD) instructions
• Optimization for controller applications
• Efficient C language support
