Product Details
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 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
– 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
