EXAR, the market leader, offers the industry's broadest line-up of UART and serial protocol transceivers solutions.

With over 200 devices, wide 2.25 to 5.5V power supply range, 1 to 128 bytes of FIFO and compliance with the universal 3.3/5V PCI, Intel and Motorola bus interfaces, including single protocol ICs that support RS-232, RS-422 or RS-485 as well as dual and multi-protocol ICs that support from 2 to 8 of the most popular interface standards with a single IC, Exar has already done the difficult work for you.

The XR17D152 (dual) and XR17D154 (quad) and XR17D158 (octal) are industry first UARTs to support both 3.3V and 5V Universal PCI Bus signaling designs. A PCI Bus add-in card designed using one of the Universal PCI UART means the card will operate virtually in any PC system, old with 5V and new at 3.3V. PC Add-in card manufacturers can simply build and ship the Universal PCI cards to the distribution channel or customers without having to concern with slot's VIO voltage compatibility.

This multi-channel Universal PCI UART product family is highly integrated and well suited for Universal PCI add-in card solutions. In addition, they support high bandwidth requirements found in communication devices of Point-of-Sale (POS) systems, industrial machineries, computer servers and telecom network management solutions for systems based on PCI Bus, CompactPCI, PMC, VME and PC/104Plus industry standards.

These Universal PCI UART devices build on the earlier successful introduction of the 5V devices (XR17C152/154/158, 2/4/8 channels), and 3.3V (XR17L152/154) and will deliver the same product innovations that have been a hallmark of Exar's offerings including: minimized design cycles, increased performance, and acceleration of time-to-market.
