PIC16C77-20I PT LQFP44 microcontroller

The PIC16C77-20I PT LQFP44 is a 20 MHz microcontroller in a 44-pin LQFP package. It suits engineers designing embedded control boards that need on-chip peripherals and moderate I/O count. The device is supplied new and ready for production or prototype assembly.

Verify voltage, clock and footprint compatibility

Confirm that your board runs at the 5 V supply this part requires and that the 20 MHz clock speed meets your timing budget. The 44-pin LQFP footprint must match your PCB land pattern and your pick-and-place data. No other electrical or mechanical parameters are provided in the data.

No accessories or software are bundled

The component ships as a bare integrated circuit without headers, sockets, cables or development tools. Firmware libraries and programming adapters must be sourced separately from Microchip or third-party vendors. The lack of bundled items keeps the bill of materials simple for volume builds.

Questions about this item

Does the PIC16C77-20I PT LQFP44 come with any accessories or must I buy a programmer separately?

The device is supplied as a standalone 44-pin LQFP integrated circuit; a compatible PIC programmer or debugger and any required sockets or adapters must be purchased separately.

How do I decide between the 20 MHz version and other speed grades for the PIC16C77?

The 20 in the part number marks a 20 MHz maximum clock rate; choose this grade when your design requires that operating frequency and the supply voltage range matches your board.

What does the 20 MHz rating mean once the PIC16C77-20I is soldered onto my PCB?

It sets the upper limit for the instruction cycle clock, so the firmware can execute up to 5 million instructions per second provided the crystal or oscillator and power supply meet the specified tolerances.
