XR16V2652

HIGH PERFORMANCE DUART WITH 32-BYTE FIFO

JUNE 2006

REV. P1.0.0

FEATURES

GENERAL DESCRIPTION

• 2.25 to 3.6 Volt Operation

• 5 Volt Tolerant Inputs

The XR16V2652 (V2652) is a high performance dual

universal asynchronous receiver and transmitter

(UART) with 32 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

• Pin-to-pin compatible to Exar’s XR16V2752 in the

44-PLCC package

ST16C2552,

XR16L2552,

XR16V2552

and

• Two independent UART channels

XR16L2752. The V2652 register set is compatible to

the ST16C2552 and the XR16V2552. It supports the

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 V2652 is

available in 44-pin PLCC and 32-pin QFN packages.

■ Register set compatible to ST16C2552

■ 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 32 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

• Telecommunication Network Routers

• Ethernet Network Routers

• Cellular Data Devices

• Factory Automation and Process Controls

• Device Identification and Revision

• Crystal oscillator or external clock input

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

(up to 64 MHz) input

• 44-PLCC and 32-QFN packages
