PRELIMINARY  
XR16V2750  
HIGH PERFORMANCE DUART WITH 64-BYTE FIFO  
JUNE 2006  
REV. P1.0.0  
FEATURES  
GENERAL DESCRIPTION  
2.25 to 3.6 Volt Operation  
5 Volt Tolerant Inputs  
1
The XR16V2750 (V2750) is a high performance dual  
universal asynchronous receiver and transmitter  
(UART) with 64 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  
ST16C2550 and XR16L2750. The V2750 register set  
is identical to the XR16L2750 and is compatible to the  
ST16C2550 and the XR16C2850 enhanced features.  
It supports the Exar’s enhanced features of  
programmable FIFO trigger level and FIFO level  
counters, automatic hardware (RTS/CTS) and  
software flow control, automatic RS-485 half duplex  
direction control output 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 8  
Mbps at 3.3 Volt and 8X sampling clock. The V2750  
is available in 48-pin TQFP and 32-pin QFN  
packages.  
Pin-to-pin compatible to Exar’s XR16L2750 and  
TI’s TL16C752B in the 48-TQFP package  
Two independent UART channels  
Register set compatible to XR16L2750  
Data rate of up to 8 Mbps at at 3.3 V, and  
6.25 Mbps at 2.5 V with 8X sampling rate  
Fractional Baud Rate Generator  
Transmit and Receive FIFOs of 64 bytes  
Programmable TX and RX FIFO Trigger Levels  
Transmit and Receive FIFO Level Counters  
Automatic Hardware (RTS/CTS) Flow Control  
Selectable Auto RTS Flow Control Hysteresis  
Automatic Software (Xon/Xoff) Flow Control  
Automatic RS-485 Half-duplex Direction  
Control Output via RTS#  
Wireless Infrared (IrDA 1.0) Encoder/Decoder  
Automatic sleep mode  
NOTE: 1 Covered by U.S. Patent #5,649,122
