Standard Asynchronous Communication Bits

(Start, Stop, and Parity) Added to or Deleted

From the Serial Data Stream

DESCRIPTION

The TL16C2552 is a dual universal asynchronous

receiver and transmitter (UART). It incorporates the

functionality of two TL16C550D UARTs, each UART

having its own register set and FIFOs. The two

UARTs share only the data bus interface and clock

source, otherwise they operate independently.

Another name for the UART function is

Asynchronous Communications Element (ACE), and

these terms will be used interchangeably. The bulk

of this document describes the behavior of each

ACE, with the understanding that two such devices

are incorporated into the TL16C2552.

•

5-V, 3.3-V, 2.5-V, and 1.8 V Operation

Independent Receiver Clock Input

Transmit, Receive, Line Status, and Data Set

Interrupts Independently Controlled

•

Fully Programmable Serial Interface

Characteristics:

– 5-, 6-, 7-, or 8-Bit Characters

– Even-, Odd-, or No-Parity Bit Generation

and Detection

– 1-, 1 ½-, or 2-Stop Bit Generation

– Baud Generation (dc to 1 Mbit/s)

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 the Texas

Instruments standard warranty. Production processing does not

necessarily include testing of all parameters.
