SMSC Introduces USB332x Hi-Speed USB 2.0 Transceiver

SMSC (Nasdaq: SMSC) announced its latest advance in Hi-Speed USB 2.0 connectivity, the USB332x transceiver family. These new Hi-Speed USB transceivers from SMSC set new standards for integration and small size, helping designers meet the tight board space and cost requirements of portable products. SMSC’s new USB332x products supplant existing Hi-Speed USB transceiver technology for the portable market by integrating previously required separate external components into one extremely small package. The USB332x is designed in a wafer-level chip scale package (WLCSP) measuring 1.95mm x 1.95mm to save 75% in board space over prior SMSC technology. It is also 50% thinner than prior SMSC technology to meet the need for thinner product profiles.

“Integration is the watchword for all of SMSC’s connectivity products, but it is especially important for products designed for the portable electronics market,” said Mark Bode, vice president of connectivity marketing at SMSC. “With the USB332x family, we’ve rolled several discrete functions into a single package, reducing design complexity, design time and overall bill of materials (BOM) cost. But most important for portable electronics, we’ve delivered this level of integration in an incredibly small footprint, which saves valuable board space for our customers.”

Portable applications now require the USB port to act as a single point of connectivity for applications like high speed data transfer, stereo audio delivery and battery charging. With SMSC’s USB332x product family, designers get the features they require and save board space in multiple ways. Since many portable products use USB connectivity for battery charging, high levels of over-voltage protection are required. Every member of the USB332x family features VBus protection up to +30V. In addition, since the USB connector is exposed to the outside world, robust ESD protection is mandatory. The USB332x family integrates ESD protection circuitry tested up to ±15KV ESD (based on IEC air discharge standard) without the need for external components. Additionally, the USB332x family features an integrated analog USB switch, which designers can use for multiple purposes.

Samples of the USB332x family are available now.
