1. General Description
This ROM-Based 8-bit micro-controller uses a fully static CMOS design technology combines higher speed and smaller size with the low power and high noise immunity of CMOS. On chip memory system includes 1.0 K bytes of ROM, and 32 bytes of static RAM. LFXTLow frequency crystal oscillator XTALStandard crystal oscillator HFXTHigh frequency crystal oscillator u 4 oscillator start-up time can be selected by programming option: 150 s, 20 ms, 40 ms, 80 ms u On-chip RC oscillator based Watchdog Timer(WDT) can be operated freely u Pull up resistors for the following pins : PA0~PA3, PB0~PB7, /MCLR, RTCC u Pull down resistors for the following pins : PA0~PA3, PB0~PB7, RTCC u 12 I/O pins with their own independent direction control
