ST16C1550/51  
2.97V TO 5.5V UART WITH 16-BYTE FIFO  
REV. 4.2.0  
OCTOBER 2003  
FEATURES  
GENERAL DESCRIPTION  
Pin and functionally compatible to SSI 73M1550/  
The ST16C1550 and ST16C1551 UARTs (here on  
denoted as the ST16C155X) are improved versions  
of the SSI 73M1550 and SSI 73M2550 UART with  
higher operating speed and lower access time. The  
ST16C155X provides enhanced UART functions with  
2550  
16 byte Transmit FIFO  
16 byte Receive FIFO with error flags  
4 selectable Receive FIFO interrupt trigger levels  
16 byte FIFOs,  
a
modem control interface,  
independent programmable baud rate generators  
with clock rates up to 1.5 Mbps. Onboard status  
registers provide the user with error indications and  
operational status. System interrupt and modem  
control features may be tailored by external software  
to meet specific user requirements. An internal  
loopback capability allows onboard diagnostics. The  
baud rate generator can be configured for either  
crystal or external clock input with the exception of  
the 28 pin ST16C1551 package (where an external  
clock must be provided). Each package type, with the  
exception of the 28 pin ST16C155X, provides a  
buffered reset output that can be controlled through  
user software. DMA monitor signals TXRDY/RXRDY  
are not available at the ST16C155X I/O pins but  
these signals are accessible through ISR register bits  
4-5. Except as listed above, all package versions  
have the same features. The ST16C155X is not  
compatible with the industry standard 16550 and will  
not work with the standard serial port driver in MS  
Windows (see pages 16-17 for details). For an MS  
Windows compatible UART, see the ST16C550.  
Modem Control Signals (CTS#, RTS#, DSR#,  
DTR#, RI#, CD#)  
Programmable character lengths (5, 6, 7, 8) with  
even, odd or no parity  
Crystal or external clock input (except 28 pin  
ST16C1551, external clock only)  
1.5 Mbps Transmit/Receive operation (24 MHz)  
with programmable clock control  
Power Down Mode (50 uA at 3.3 V, 200 uA at 5 V)  
Software controllable reset output  
2.97 to 5.5 Volt operation
