Exar Corp. announced the XR16V2x5x series of UART products, which is composed of nine different devices, all sharing a similar core feature set. These features include PowerSave mode, automatic sleep mode, Intel/Motorola bus interface, 5V tolerant inputs, operating voltages of 2.25V to 3.63V and a fractional baud rate generator. In addition, each device has selectable TX and RX FIFO trigger levels, automatic hardware and software controls and a wireless infrared encoder/decoder.

At 16Mbps, said the press release, the XR16V2x5x series is the first in a new generation of feature rich devices supporting faster data rates required by telecommunications and Ethernet routers, cellular data devices, portable appliances and factory automation/process control.

"The XR16V2x5x series has numerous features that quickly differentiates it in the marketplace such as a programmable fractional baud rate generator with prescaler, lower operating voltages and 5V tolerant inputs and several FIFO choices," said Levent Ozcolak, division vice president and general manager for Exar's Interface Products Division. "Equally compelling, we are offering higher performance without a price premium; this is a key advantage to our customers answering the demand for lower power devices in a cost-sensitive market environment."

The XR16V2550/51/52 series are 16-byte FIFO devices; the XR16V2650/51/52 series are 32-byte FIFO devices and the XR16V2750/51/52 series are 64-byte FIFO devices. The XR16V2750/51/52 devices have additional features such as programmable trigger levels and Auto RS-485 half-duplex direction control.

The XR16V2550, XR16V2551, XR16V2650, XR16V2651, XR16V2750 are all available in either a 48-pin TQFP or a 32-pin QFN package. The XR16V2552, XR16V2652 and XR16V2752 are available in either a 44-pin PLCC, or a 32-pin QFN package. The XR16V2751 is offered in a 48-pin TQFP package. All nine devices are already available, operate over the commercial temperature range, and are priced in the mid-$3 range in 1,000-piece quantities.

The XR16V2x5x series is supported by standard serial port software drivers for popular operating systems, including Windows CE 4.2 and 5.0, XP and Linux.
