General Description
⢠Serial peripheral interface module (SPI)
⢠IRQ external interrupt pin with integrated pullup
⢠8-bit keyboard wakeup port with programmable pullup
⢠32 general-purpose input/output (I/O) pins:
â High current 8-mA sink capability on PTB2âPTB5
â High current 20-mA sink capability on PTB0âPTB1
⢠4/3 backplanes and static with maximum 27 frontplanes liquid
crystal display (LCD) driver
⢠6-channel, 10-bit successive approximation analog-to-digital
converter (ADC)
⢠Resident routines for in-circuit programming and EEPROM
emulation
⢠Low-power design (fully static with stop and wait modes)
⢠Master reset pin (with integrated pullup) and power-on reset
⢠Spike filter protection for EMC performance enhancement
⢠System protection features
â Optional computer operating properly (COP) reset, driven by
internal 64-kHz RC oscillator
â Low-voltage detection with optional reset or interrupt
â Illegal opcode detection with reset
â Illegal address detection with reset
⢠64-pin quad flat pack (QFP), 64-pin low-profile quad flat pack
(LQFP), 52-pin low-profile quad flat pack (LQFP), and die form
⢠Specific features of the MC68HC908LJ12 in 52-pin LQFP are:
â 20 general-purpose I/Os only
â High current 8-mA sink capability on PTB2âPTB3 only
â 4-bit keyboard wakeup port with programmable pullup
â No serial peripheral interface module (SPI)
â No TIM2 input capture/output compare pins
â 4-channel analog-to-digital converter only
