ST16C2550  
2.97V TO 5.5V DUART WITH 16-BYTE FIFO  
JANUARY 2011  
REV. 4.4.1  
FEATURES  
GENERAL DESCRIPTION  
Added feature in devices with top mark date code  
of "A2 YYWW" and newer:  
The ST16C2550 (C2550) is a dual universal  
asynchronous receiver and transmitter (UART). The  
ST16C2550 is an improved version of the PC16550  
UART with higher operating speed and faster access  
times. The C2550 provides enhanced UART  
functions with 16 byte FIFO’s, a modem control  
interface, and data rates up to 4 Mbps. Onboard  
status registers provide the user with error indications  
and operational status. System interrupts and modem  
control features may be tailored by external software  
to meet specific user requirements. Independent  
programmable baud rate generators are provided to  
select transmit and receive clock rates from 50 bps to  
4 Mbps. The Baud Rate Generator can be configured  
for either crystal or external clock input. An internal  
loopback capability allows onboard diagnostics. The  
C2550 is available in a 44-pin PLCC and 48-pin  
TQFP packages. The C2550 is fabricated in an  
advanced CMOS process capable of operating from  
2.97 volt to 5.5 volt power supply.  
5 Volt Tolerant Inputs  
Pin-to-pin compatible to Exar’s ST16C2450,  
XR16L2550 and XR16L2750  
Pin-to-pin compatible to TI’s TL16C752B on the 48-  
TQFP package  
Pin alike XR16C2850 48-TQFP package but  
without CLK8/16, CLKSEL and HDCNTL inputs  
2 independent UART channels  
Up to 4 Mbps with external clock of 64 MHz  
Up to 1.5 Mbps data rate with a 24 MHz crystal  
frequency  
16 byte Transmit FIFO to reduce the bandwidth  
requirement of the external CPU  
16 byte Receive FIFO with error tags to reduce  
the bandwidth requirement of the external CPU  
4 selectable Receive FIFO interrupt trigger  
levels  
APPLICATIONS  
Modem control signals (CTS#, RTS#, DSR#,  
Portable Appliances  
DTR#, RI#, CD#)  
Telecommunication Network Routers
