ST16C454  
ST68C454  
QUAD UNIVERSAL ASYNCHRONOUS  
RECEIVER/TRANSMITTER (UART)  
DESCRIPTION  
The ST16C454 is a universal asynchronous receiver  
and transmitter (UART) with a dual foot print interface.  
The 454 is an enhanced UART with data rates up to  
1.5Mbps and software compatible to ST16C450.  
Onboard status registers provide the user with error  
indications and operational status, modem interface  
control. System interrupts may be tailored to meet  
user requirements. An internal loop-back capability  
allows onboard diagnostics. The ST16C454 offer an  
additional 68 mode which allows easy integration with  
Motorola, and other popular microprocessors. The  
454 combines the package interface modes of the  
ST16C454 and ST68C454 series on a single inte-  
grated chip.
