Component identity

The YINGHUA SST25WF020-40-5IQAE is a semiconductor integrated circuit supplied in a QFN8 package. It is intended for engineers and technicians who require this specific device for circuit design, prototyping or repair work.

Package and handling

The QFN8 footprint demands precise surface-mount soldering onto a matching PCB land pattern. Its small outline suits dense board layouts but requires reflow equipment and inspection capability for reliable assembly.

Supply format

Each order delivers a single new device as listed on 21 February 2025. No programmer adapters, sockets or development software are bundled, so users must provide their own tooling and firmware environment.

Questions about this item

What SPI clock frequency does the SST25WF020-40-5IQAE support?

The device operates at up to 40 MHz on the SPI bus, which caps the practical transfer rate for read and write cycles.

What board footprint does the QFN8 package need?

The 8-lead QFN8 body requires an 8-pad land pattern with a centre thermal pad matching the package outline.

How is the chip mounted, and what step is often missed?

Place the QFN8 on the solder-paste pads, reflow, then inspect the centre thermal pad for voids — insufficient wetting there is the common oversight.
