Microchip PIC16F636-I/SL, 8bit PIC Microcontroller, PIC16F, 20MHz, 2048 words Flash, 14-Pin SOIC

The PIC16F range of microcontrollers from Microchip are 8-bit MCUs that incorporate Microchip’s PIC® architecture into a variety of pin and package options, from space efficient 14-pin devices to feature-rich 64-pin devices. Devices with Baseline, Mid-Range or Enhanced Mid-Range architecture are available with numerous different peripheral combinations, giving designers flexibility and choice for their applications.

The PIC16F636/639 family of microcontrollers is based upon Microchip’s Mid-Range core with an 8 level deep hardware stack and 35 instructions. These MCUs provide up to 5 MIPS, 3.5 Kbytes program memory, 128 bytes RAM and 256 bytes EEPROM. On board is a configurable oscillator factory calibrated to ±1% accuracy.
