description  
The TL16C550D and the TL16C550DI are speed and operating voltage upgrades (but functional equivalents)  
of the TL16C550C asynchronous communications element (ACE), which in turn is a functional upgrade of the  
TL16C450. Functionally equivalent to the TL16C450 on power up (character or TL16C450 mode), the  
TL16C550D and the TL16C550DI, like the TL16C550C, can be placed in an alternate FIFO mode. This relieves  
the CPU of excessive software overhead by buffering received and transmitted characters. The receiver and  
transmitter FIFOs store up to 16 bytes including three additional bits of error status per byte for the receiver  
FIFO. In the FIFO mode, there is a selectable autoflow control feature that can significantly reduce software  
overload and increase system efficiency by automatically controlling serial data flow using RTS output and CTS  
input signals.  
The TL16C550D and TL16C550DI perform serial-to-parallel conversions on data received from a peripheral  
device or modem and parallel-to-serial conversion on data received from its CPU. The CPU can read the ACE  
status at any time. The ACE includes complete modem control capability and a processor interrupt system that  
can be tailored to minimize software management of the communications link.  
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of  
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
