General Description
⢠Timebase module
⢠Serial communications interface module 1 (SCI)
⢠Serial communications interface module 2 (SCI) with infrared (IR) encoder/decoder
⢠Serial peripheral interface module (SPI)
⢠System management bus (SMBus), version 1.0/1.1 (multi-master IIC bus)
⢠8-channel, 10-bit analog-to-digital converter (ADC)
⢠IRQ1 external interrupt pin with integrated pullup
⢠IRQ2 external interrupt pin with programmable pullup
⢠8-bit keyboard wakeup port with integrated pullup
⢠32 general-purpose input/output (I/O) pins:
â 31 shared-function I/O pins
â 8 LED drivers (sink)
â 6 Ã 25mA open-drain I/O with pullup
⢠Low-power design (fully static with stop and wait modes)
⢠Master reset pin (with integrated pullup) and power-on reset
⢠System protection features
â Optional computer operating properly (COP) reset, driven by internal RC oscillator
â Low-voltage detection with optional reset or interrupt
â Illegal opcode detection with reset
â Illegal address detection with reset
⢠48-pin low quad flat pack (LQFP), 44-pin quad flat pack (QFP), and 42-pin shrink dual-in-line
package (SDIP)
⢠Specific features of the MC68HC908AP64 in 42-pin SDIP are:
â 30 general-purpose l/Os only
â External interrupt on IRQ1 only
Features of the CPU08 include the following:
⢠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 à 8 multiply instruction
⢠Fast 16/8 divide instruction
⢠Binary-coded decimal (BCD) instructions
⢠Optimization for controller applications
⢠Efficient C language support
