Microchip PIC16C622A-04I/SO, 8bit PIC Microcontroller, PIC16C, 20MHz, 8 kB Flash, 18-Pin SOIC

The Microchip PIC16C622A 8-bit CMOS microcontroller has a RISC architecture. It operates on 2.5V to 5.5V voltage range. This microcontroller features eight-level deep stack, and multiple internal and external interrupt sources. The separate instruction and data buses of the Harvard architecture allow a 14-bit wide instruction word with the separate 8-bit wide data. The two-stage instruction pipeline allows all instructions to execute in a single cycle, except for program branches (which require two cycles). A total of 35 instructions (reduced instruction set) are available. It features 20 I/O pins, 2KBytes EEPROM and 128Bytes Data memory.Low power, high speed CMOS EPROM technology Fully static design Frequency range of 200 kHz 13 I/O pins with individual direction control High current sink/source for direct LED drive Two analog comparators Programmable on-chip voltage reference (VREF) module Programmable input multiplexing from device inputs and internal voltage reference Comparator outputs can be output signals Power-on Reset (POR) Power-up Timer (PWRT) and Oscillator Start-up Timer (OST) Brown-out Reset Watchdog Timer (WDT) with its own on-chip RC oscillator for reliable operation Programmable code protection Power saving SLEEP mode Selectable oscillator options Serial in-circuit programming (via two pins) Four user programmable ID locations Low power consumption Temperature range between 0°C and +70°C SOIC package
