Description
M68hc08 Microcontrollers
Manufacturer
Freescale Semiconductor, Inc
Datasheet
General Description
Features of the CPU08 include:
20
Timebase Module (TBM)
5-bit keyboard interrupt (KBI) with wakeup feature
24 general-purpose input/output (I/O) pins
External asynchronous interrupt pin with internal pullup (IRQ)
System protection features:
Low-power design; fully static with stop and wait modes
Internal pullups on IRQ and RST to reduce customer system cost
Standard low-power modes of operation:
Master reset pin (RST) and power-on reset (POR)
BREAK module (BRK) to allow single breakpoint setting during in-circuit debugging
Higher current source capability on nine port lines for LED drive (PTA6/SS, PTA5/SPSCK,
PTA4/KBD4, PTA3/KBD3, PTA2/KBD2, PTA1/KBD1, PTA0/KBD0, PTC1/MOSI, and PTC0/MISO)
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
Third party C language support
32-pin quad flat pack (QFP) package
Optional computer operating properly (COP) reset
Illegal opcode detection with reset
Illegal address detection with reset
Wait mode
Stop mode
