General Description
Introduction
The MC68HC908GR60A, MC68HC908GR48A, and MC68HC908GR32A are 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.
Features
For convenience, features have been organized to reflect:
? Standard features
? Features of the CPU08
Standard Features
Features of the MC68HC908GR60A include:
? High-performance M68HC08 architecture optimized for C-compilers
? Fully upward-compatible object code with M6805, M146805, and M68HC05 Families
? 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
– MC68HC908GR48A — 48 Kbytes
– MC68HC908GR32A — 32 Kbytes
? Random-access memory (RAM):
– MC68HC908GR60A — 2048 bytes
– MC68HC908GR48A — 1536 bytes
– MC68HC908GR32A — 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 B is 8 bits: PTB0–PTB7; shared with ADC module
– Port C is only 7 bits: PTC0–PTC6
– Port D is 8 bits: PTD0–PTD7; shared with SPI, TIM1, andTIM2 modules
– Port E is only 6 bits: PTE0–PTE5; shared with ESCI module
– Port F is 8 bits: PTF0–PTF7; shared with TIM2 module
– Port G is 8 bits; PTG0–PTG7; shared with ADC module
