XR16V2552

HIGH PERFORMANCE DUART WITH 16-BYTE FIFO

MARCH 2010

REV. 1.0.3

FEATURES

GENERAL DESCRIPTION

• 2.25 to 3.6 Volt Operation

• 5 Volt Tolerant Inputs

The XR16V2552 (V2552) is a high performance dual

universal asynchronous receiver and transmitter

(UART) with 16 byte 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

ST16C2552 and XR16L2552. The V2552 register set

is compatible to the ST16C2552 and the XR16L2552.

It supports the Exar’s enhanced features of

selectable FIFO trigger level, automatic hardware

(RTS/CTS) and software (Xon/Xoff) 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 V2552 is available in 44-pin

PLCC and 32-pin QFN packages.

• Pin-to-pin compatible to Exar’s XR16L2552 in the

44-PLCC package

• Two independent UART channels

■ Register set identical to 16V2550

■ 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

APPLICATIONS

• Alternate Function Register

• Portable Appliances

• Device Identification and Revision

• Telecommunication Network Routers

• Ethernet Network Routers

• Crystal oscillator (up to 32MHz) or external clock

(up to 64MHz) input

• 44-PLCC and 32-QFN packages

• Cellular Data Devices

• Factory Automation and Process Controls
