PRELIMINARY  
XR16M2750  
HIGH PERFORMANCE DUART WITH 64-BYTE FIFO  
JUNE 2007  
REV. P1.0.0  
FEATURES  
GENERAL DESCRIPTION  
1.62 to 3.6 Volt Operation  
1
The XR16M2750 (M2750) is a high performance  
dual universal asynchronous receiver and transmitter  
(UART) with 64 byte TX and RX FIFOs. The device  
operates from 1.62 to 3.6 volts and is pin-to-pin  
compatible to Exar’s ST16C2550 and XR16V2750.  
The M2750 register set is identical to the XR16V2750  
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 M2750 is available in 48-pin  
TQFP and 32-pin QFN packages.  
Pin-to-pin compatible to Exar’s XR16V2750 and  
TI’s TL16C752B in the 48-TQFP package  
Two independent UART channels  
Register set compatible to XR16V2750  
Data rate of up to 8 Mbps at 3.3 V, 6.25 Mbps  
at 2.5 V and 4 Mbps at 1.8 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#  
NOTE: 1 Covered by U.S. Patent #5,649,122  
Wireless Infrared (IrDA 1.0) Encoder/Decoder  
Automatic sleep mode
