What it is

The YINGHUA AT89LP828-20MH is a new 32-VQFN integrated circuit supplied as a discrete semiconductor component. It is intended for engineers and procurement teams sourcing this specific part number for board-level assembly or repair.

When the upgrade applies

This device replaces an existing AT89LP828-20MH on a 32-VQFN footprint when the original part has failed or reached end of life. The jump is worth it when the bill of materials calls for this exact package and speed grade.

Who it suits

It suits buyers who need the AT89LP828-20MH in a 32-VQFN package for a qualified design. Builders who require a different pin count, voltage range or temperature grade should look at something else.

Questions about this item

What footprint and pin count does the 32-VQFN package need on the PCB?

The device uses a 32-pin VQFN footprint; design the land pattern for 32 pads with the exposed thermal pad connected to ground.

What is the correct orientation for reflow soldering the AT89LP828-20MH?

Align the pin-1 indicator on the IC with the pin-1 mark on the PCB silkscreen before reflow; misalignment is the most common assembly error.

How long can the on-chip flash retain data after programming?

The flash memory is rated for 20-year data retention at room temperature after the last erase or write cycle.
