MC68HC908EY16 Datasheet, PDF (20/278 Pages) Motorola, Inc – Microcontrollers

General Description
• 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:
– Optional computer operating properly (COP) reset
– Illegal opcode detection with reset
– Illegal address detection with reset
• 32-pin quad flat pack (QFP) package
• 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:
– Wait mode
– Stop mode
• 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)
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
• Third party C language support
