Exar Corp. has launched two highly integrated, low-power 8-channel UARTsthe XR16M598 (16byte FIFO) and XR16M698 (32byte FIFO).

The XR16M598/M698 series, integrated with an array of advanced features, is suitable for a wide variety of products such as next generation portable consumer devices, point-of-sale, servers, industrial automation, ticketing machines and public parking systems.

This high performance (15Mbit/s), low-power (1.62V) octal UART series has a wide range of features, including a patented global interrupt status register, fractional baud rate generator, and automatic hardware or software flow control. Exar said its other features also include programmable TX/RX trigger levels; automatic RS-485 half-duplex direction control; and IR mode (IrDA 1.0) that enable system architects to optimize their designs and accelerate their time-to-market.

Also, there is an easy migration path as the series is software and pin compatible with the 3.3V XR16V598/V698/V798 and 5V XR16L788. Both devices are in a 100-pin QFP package and operate over the industrial temperature range.
