PIC16C642-20I/SO microcontroller for embedded

The PIC16C642-20I/SO is a Microchip 8-bit microcontroller supplied in a 28-pin SOP package. It suits engineers and hobbyists building compact control boards, sensor interfaces or legacy equipment repairs. The industrial temperature rating supports operation in demanding environments. This new component arrives ready for soldering onto custom PCBs.

SOP28 package fits dense layouts

The small-outline 28-lead footprint allows tight routing on space-constrained boards, leaving room for supporting passives, connectors or additional logic. A 20 MHz clock speed provides deterministic timing for real-time tasks without external crystal complexity. Designers needing more I/O lines or larger program memory must select a different device. The part integrates core peripherals, reducing the external component count for simpler assembly.
