Description

Combining

Oxford

Semiconductor’s

high

performance UART and 16-bit PC Card/Compact

Flash technology, the OXCF950B is the ideal

connectivity solution for products that need to

bridge serial devices to 16-bit PC Card or

Compact Flash interfaces including: Cellular

CDMA/GSM/GPRS, GPS, and Bluetooth wireless

data cards.

This highly integrated device is backed by

certified device drivers, for a wide range of

operating

systems,

to

deliver

ultimate

performance with reduced design cycles and

accelerated time to market.

The OXCF950B is a single chip serial port

solution for 16-bit PC Card and Compact Flash
