PIC16F631/677/685/687/689/690 8-Bit Flash Microcontrollers. 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 PIC16F631/677/685/687/689/690 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, up to 7 Kbytes program memory, up to 256 bytes RAM and Data EEPROM of up to 256 bytes. On board is a configurable oscillator factory calibrated to ±1% accuracy.
