XR16V2550

HIGH PERFORMANCE DUART WITH 16-BYTE FIFO

JUNE 2006

REV. P1.0.0

FEATURES

GENERAL DESCRIPTION

• 2.25 to 3.6 Volt Operation

• 5 Volt Tolerant Inputs

The XR16V2550 (V2550) is a high performance dual

universal asynchronous receiver and transmitter

(UART) with 16 bytes TX and RX FIFOs. The device

operates from 2.25 to 3.6 volts with 5 Volt tolerant

inputs and is pin-to-pin compatible to Exar’s

ST16C2550 and XR16C2550. The V2550 register set

is compatible to the ST16C2550 and the XR16L2550.

It supports Exar’s enhanced features of selectable

FIFO trigger level, automatic hardware (RTS/CTS)

and software flow control, and a complete modem

interface. Onboard registers provide the user with

operational status and data error flags. An internal

loopback capability allows system diagnostics.

Independent programmable baud rate generators are

provided in each channel to select data rates up to 16

Mbps at 3.3 Volt with 4X sampling clock. The V2550

is available in 48-pin TQFP and 32-pin QFN

packages.

• Pin-to-pin compatible to ST16C2550, XR16C2550

and XR16L2550 in the 48-TQFP package

• Two independent UART channels

■ Register set compatible to XR16L2550

■ Data rate of up to 16 Mbps at 3.3 V, and 12.5

Mbps at 2.5 V with 4X sampling rate

■ Fractional Baud Rate Generator

■ Transmit and Receive FIFOs of 16 bytes

■ Selectable TX and RX FIFO Trigger Levels

■ Automatic Hardware (RTS/CTS) Flow Control

■ Automatic Software (Xon/Xoff) Flow Control

■ Wireless Infrared (IrDA 1.0) Encoder/Decoder

■ Automatic sleep mode

NOTE: 1 Covered by U.S. Patent #5,649,122

■ Full modem interface
