Microcontroller IC

The YINGHUA PIC18F57Q84-I PT is a semiconductor device supplied in a 48-pin TQFP package. It is intended for engineers designing embedded control systems who need a microcontroller core with integrated peripherals. The part is stocked in new condition and identified by the manufacturer part number printed on the reel label.

Target users and alternatives

This component suits developers working with the PIC18 architecture who require the specific peripheral set defined by the 57Q84 designation. It is not for hobbyists needing a development board with onboard debug hardware, nor for designs that demand a higher pin-count package or a different core architecture.

Deciding specification

The 48-lead TQFP footprint fixes the board layout and routing density for this device. Verify that your PCB design matches this exact package outline before ordering, as the pin count and body dimensions are not interchangeable with other variants in the same family.

Questions about this item

What PCB footprint do I need for the 48-pin TQFP package?

The device uses a 48-pin TQFP package, so design the board with a matching 48-lead TQFP footprint and the correct pitch.

Can the PIC18F57Q84-I share a 5 V bus with legacy 5 V peripherals?

Check the datasheet voltage range; if the part is rated for 5 V operation it can share the bus, otherwise use level shifters.

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

Toggle a GPIO pin at start-up and probe it with an oscilloscope or LED to verify the firmware is executing.
