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 2.0 K bytes of ROM, and 80 bytes of static RAM. u 4 oscillator start-up time : 150 s, 20 ms, 40 ms, 80 ms u 8-bit real time clock/counter(RTCC) with 8-bit programmable prescaler u 4 types of oscillator can be selected by code options : RCLow cost RC oscillator LFXTLow frequency crystal oscillator XTALStandard crystal oscillator HFXTHigh frequency crystal oscillator 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,PC0~PC7, /MCLR, RTCC u Pull down resistors for the following pins : PA0~PA3, PB0~PB7, PC0~PC7, RTCC u 20 I/O pins with their own independent direction control
