Product details

The Microchip PIC16F689-I/SS is an 8-bit PIC® 16F microcontroller running at 20 MHz, with 7 KB (4K x 14) Flash program memory, 256 x 8 bytes of RAM, and a separate 256 x 8 EEPROM block for nonvolatile data storage.

Memory and peripheral budget for the BOM

With 7 KB Flash and 256 bytes of RAM, this MCU targets code footprints under about 6 KB after bootloader overhead — think simple control loops, sensor polling, and serial protocol handling. The 256-byte EEPROM is a separate block, not bank-switched from Flash, so you can store calibration constants or configuration data without wearing the program memory. The 12-channel 10-bit ADC covers analog inputs like temperature sensors, potentiometers, or current-sense resistors without an external converter, saving board space and cost.

It is ROHS3 compliant. Sourcing is straightforward through independent distribution; we can quote current pricing and availability against an RFQ for production or prototype quantities.
