Exar introduces industry's first 1.8V single-channel UART in 24 and 32-QFN packages

2006-03-22

The industry’s lowest voltage single-channel UART is now available from DT Electronics. At 1.8V, in 32-QFN (5mm x 5mm) and 24-QFN (4mm x 4mm) packages, the multi-purpose XR16L570 from Exar is ideal for a variety of battery operated portable consumer products including mobile devices, smart phones, gaming systems, and PDAs.

The XR16L570 is a 1.8V to 5V device with 5V tolerant inputs. It features 16-byte Transmit (TX) and Receive (RX) FIFOs with selectable trigger levels, automatic software and hardware flow control, and infrared (IrDA 1.0) encoder/decoder. The PowerSave mode further reduces power consumption during sleep mode to less than 5uA at 1.8V over the industrial temperature range (-40 deg C to +85 deg C). The UART has the industry standard 16C550 register set and enhanced features that support Intel’s 8-bit data bus interface. The XR16L570 is supported by drivers for popular real-time operating systems including Windows CE and VxWorks.
