YINGHUA PIC18F87K22-EPT TQFP80 Microcontroller

This new microcontroller is an 8-bit PIC18F device in an 80-pin TQFP package. It is intended for embedded designers who need the specific peripherals and pin count defined by the 87K22 part number. The component is supplied as a discrete integrated circuit for custom board assembly.

Suits engineers building with the PIC18F87K22

This part suits engineers who have validated firmware for the PIC18F87K22 and require the exact 80-pin TQFP footprint. It is not for buyers who need a different pin count, a different package style, or a device with a different peripheral set. Buyers who want a drop-in replacement for a different microcontroller should look elsewhere.

80-pin TQFP package defines board compatibility

The single specification that decides fit is the 80-pin TQFP package. The PCB must be laid out for this exact footprint and pitch. If the board uses a different package or pin count, this IC cannot be used.

Questions about this item

What programmer voltage level is required to program the PIC18F87K22-EPT?

The PIC18F87K22-EPT operates within a standard voltage range for PIC18F devices; use a programmer that supports low-voltage ICSP for this 80-pin TQFP microcontroller.

Can the PIC18F87K22-EPT share an SPI bus with legacy 5 V peripherals?

The PIC18F87K22-EPT I/O pins are not 5 V tolerant; add level shifters when connecting the 18F87K22 SPI lines to older 5 V devices.

How do I confirm the PIC18F87K22-EPT is running after power-up?

Toggle an output pin in firmware and measure the signal with an oscilloscope or logic analyser; a steady square wave shows the 87K22 core is executing code.
