XR28V382

3.3V DUAL LPC UART WITH 128-BYTE FIFO

DECEMBER 2013

REV. 1.0.1

FEATURES

GENERAL DESCRIPTION

x 128 Byte Transmit and Receive FIFO

x Compliant to LPC 1.1 Specifications

x -40°C to +85°C Industrial Temp Operation

x Watchdog Timer with WDTOUT# signal

x 2 independent UART channels

The XR28V382 (V382) is

dual Universal

Asynchronous Receiver and Transmitter (UART) for

the Intel Low Pin Count (LPC) bus interface. This

device can replace or supplement a Super I/O device

to add additinal serial ports to the system.

The V382 UARTs support any 16-bit I/O address

supported by the system. The register set is based on

the industry standard 16550 UART, so the V382

operates with standard serial port drivers without

requiring a custom driver to be installed.

■ Programmable I/O mapped base addresses

■ Data rates up to 3 Mbps

■ Selectable RX FIFO interrupt trigger levels

■ Auto RS-485 Half-Duplex Control mode

The 128 byte Transmit and Receive FIFOs reduce

CPU overhead and minimize the chance of buffer

overflow and data loss. In addition to the 16550 UART

registers, there are also Configuration register set

where enhanced features such as the 9-bit (multidrop)

mode, IrDA mode and the Watchdog Timer can be

enabled.

■ Programmable character lengths (5, 6, 7, 8)

with even, odd, or no parity

■ IrDA mode and separate IRTXA# and IRRXA#

pins for the first UART channel

■ 9-bit (Multidrop) mode

x External 24MHz/48MHz clock

x Single 3.3V Supply Voltage ( 10%)

x 5V tolerant inputs

The V382 is available in a 32-pin QFN package.

APPLICATIONS

x Industrial and Embedded PCs

x Factory Automation and Process Controls

x Network Routers

x 32-QFN package (5mm x 5mm)

x System Board Designs
