Single IC semiconductor component

The YINGHUA SST25WF040-40-5I-QAE is a new discrete IC supplied in a QFN8 package for integration onto printed circuit boards. It serves engineers and hobbyists who need one specific semiconductor device for prototyping or repair work.

25 MHz operating limit with 40 °C thermal boundary

The part is rated for operation up to 25 MHz and functions within a 40 °C temperature envelope. Performance headroom ends at those limits, so designs requiring higher clock rates or extended temperature ranges cannot use this device.

Loose single-unit packaging

Only the bare IC is included; no socket, adapter, programming header or development software is bundled. The buyer must provide all supporting hardware and toolchain for programming and board-level integration.

Questions about this item

Will the SST25WF040-40-5I-QAE QFN8 fit the existing QFN8 footprint on my board?

Yes, the QFN8 package matches the standard QFN8 footprint, so it will sit on the same pads you already use.

How can I confirm the SST25WF040-40-5I-QAE QFN8 is operating correctly after soldering?

Power the board and verify the device responds on the SPI bus with the correct manufacturer and device ID codes.

Does the single SST25WF040-40-5I-QAE QFN8 come with any sockets, adapters or programming headers?

No, the listing is for one bare QFN8 IC only; any socket, adapter or programmer must be sourced separately.
