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  
1
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
