The Microchip 8-Pin flash based 8 bit CMOS microcontroller has only 35 instructions to learn all single-cycle instructions except branches. It has wide operating voltage range from 2.0 V to 5.5 V. It has 8-Level deep hardware stack and direct, indirect, and relative addressing modes. The 6 I/O pins are with Individual direction control and high current sink/source for direct LED drive.Power saving sleep modeWide operating voltage range 2.0 V to 5.5 VIndustrial and extended temperature rangelow power on reset (POR)Power up timer (PWRT) and Oscillator start up timer (OST)Brown-out Detect (BOD)Watchdog timer (WDT) with independentOscillator for reliable operationMultiplexed MCLR/input pinInterrupt-on-pin changeIndividual programmable weak pull-upsProgrammable code protection
