Fast SD card readers now with high speed functionality

Paul Boughton

Yamaichi Electronics has extended their core competences to include a new series UHSII SD card reader. UHS-II is the version 2 of the Ultra High Speed (UHS) bus classification for the SD Flash memory cards.

In the meantime, this segment has become a large product family that serves different markets including consumer, automotive, and industrial with a wide range of products.

Now Yamaichi also offers the FPS017T series which not only extends both the SD card reader family but also represents a practical extension to the High Speed product line, for which Yamaichi offers a variety of internal and I/O connectors.

The FPS017T series was developed for generation 4.0 SD cards and therefore meets UHS-II requirements. That means that instead of the usual nine contacts, this reader now has 17 contacts to support transmission rates of up to 312 Mbit per second.

Yamaichi offers this new generation of card readers in top and reverse mount versions (FPS017T-1000-x or FPS017T-2000-x). A closed metal housing with four tabs for connection to the circuit board ensures good EMC shielding. The FPS017T series offers a convenient push/push mechanism, that is, the card engages when pressed once. When it is pressed again, the mechanism releases it and the card can safely be removed. A card brake provides the definitive ejection of the card.

A card presence switch ensures that the read/write process only starts or stops when the card is completely inserted or removed. This guarantees data transmission and prevents data loss.

Depending on customer requirements and the application, contacts are available in different gold plating variants – from Gold flash to 30µinch.

The card readers are delivered in trays or tape-and-reel packaging as needed, offering the greatest possible flexibility in assembly.
