Bridge chip simplifies wireless interface design

The VMB5000 is billed as the world's first multifunction bridge chip designed to exceed the data transfer speed requirements of current 3G wireless datacards and beyond.

The VMB5000 is billed as the world's first multifunction bridge chip designed to exceed the data transfer speed requirements of current 3G wireless datacards and beyond with 20Mbyte/s host interface capability.

A single chip solution, it is a true multifunction device aimed at 3G/WLAN combo cards, and is designed to greatly simplify the card design process.

In addition to its high speed performance, the chip offers 16bit PCMCIA stability and very low power consumption.

Great flexibility for card designers is provided with a choice of client interface including USB or UART.

The two 16Kbyte FIFOs deliver sustained throughput of up to 10Mbyte/s with UART or 12Mbyte/s with USB.

Additionally, there is a smart card interface mode and support for popular synchronous local bus protocols.

Packaged in a 9 x 9 x 1.1mm 64-pin x 1.0mm VQFN, this device offers a simple and particularly cost effective solution for wireless data card designers.

A full reference kit is available to facilitate the test and design process.
