description

The TL16C750 is a functional upgrade 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 TL16C750, like the TL16C550C, can be placed in an alternate mode (FIFO

mode). This relieves the CPU of excessive software overhead by buffering received and transmitted characters.

The receiver and transmitter FIFOs store up to 64 bytes including three additional bits of error status per byte

for the receiver FIFO. The user can choose between a 16-byte FIFO mode or an extended 64-byte FIFO mode.

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 through the RTS output and the CTS

input signals (see Figure 1).

The TL16C750 performs serial-to-parallel conversion 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.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of Texas Instruments

standard warranty. Production processing does not necessarily include

testing of all parameters.
