8 Mbps UART delivers high speed to industrial applications

Exar Corp. has expanded its family of Universal Asynchronous Receiver Transmitter devices with the introduction of eight channel 8 Mbps UART targeted at the high speed data transmission requirements of a variety of industrial applications including remote access servers, network management, factory automation/process control and multi-port RS-232/RS-422/RS-485 communications cards.

The eight-channel XR16V798 is a 2.25V to 3.6V device with 5V tolerant inputs. The device features 64-byte Transmit (TX) and Receive (RX) FIFOs with fully programmable trigger levels, automatic RTS/CTS or DTR/DSR hardware flow
control with programmable hysteresis, automatic software (Xon/Xoff) flow control, RS-485 half-duplex direction control with programmable turn-around delay, Intel or Motorola bus interface and sleep mode with a wake-up
indicator.

It also has the industry standard 16C550 register set, and is pin-for-pin compatible with Exar's XR16L788 (8-channel, 8-bit data bus) device. The XR16V798 is supported by Exar's UART software drivers for popular operating systems including Windows 2000, XP and Linux.

The XR16V798 is available now in 100-pin QFP packages at $20.13 for 1,000 pieces. The device operates over the industrial temperature range of -40 degrees C to +85 degrees C.
