TL16PNP550A

ASYNCHRONOUS COMMUNICATIONS ELEMENT

WITH PLUG-AND-PLAY (PnP) AND AUTOFLOW CONTROL

SLLS190B – MARCH 1995 – REVISED MARCH 1996

PnP Card Autoconfiguration Sequence

On-Chip I/O Port Address Decoding

Compliant

In PnP Bypass Mode, 6 External Terminals

Configure the I/O Base Address and

Interrupt Mapping

External Terminal-to-Bypass PnP

Autoconfiguration Sequence

Adds or Deletes Standard Asynchronous

Communication Bits (Start, Stop, and

Parity) to or From the Serial Data Stream

In UART Bypass Mode, the Stand-Alone

PnP Controller is Configured With One

Logical Device

Independent Control of Transmit, Receive,

Line Status, and Data Set Interrupts on

Each Channel

Provides 10-Interrupts IRQ3–IRQ7,

IRQ9–IRQ12, IRQ15

Simple 3-Pin Interface to SGS-Thomson

EEPROM 2K/4K ST93C56/66

Programmable Serial Interface

Characteristics:

– 5-, 6-, 7-, or 8-Bit Characters

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

and Detection

– 1-, 1 1/2-, or 2-Stop Bit Generation

– Baud Generation (DC to 1 Mbit Per

Second)

High Output Current Drive. No External

Buffer Needed for Data and Interrupt

Signals

Programmable Auto-RTS and Auto-CTS

In Auto-CTS Mode, CTS Controls

Transmitter

In Auto-RTS Mode, Receiver FIFO Contents

and Threshold Control RTS

False Start Bit Detection

Complete Status Reporting Capabilities

The Serial and Modem Control Outputs

Drive a 1-Meter RJ11 Cable Directly if

Equipment Is on the Same Power Drop

3-State Outputs Provide TTL Drive for

Bidirectional Data Bus and Interrupt Lines

Line Break Generation and Detection

Capable of Running With All Existing

TL16C450 Software

Internal Diagnostic Capabilities:

– Loopback Controls for Communications

Link Fault Isolation

– Break, Parity, Overrun, and Framing

Error Simulation

After Reset, All Registers Are Identical to

the TL16C450 Register Set

Clock Prescalar Allows 22-MHz Oscillator

Clock to be Divided by 12, 6, 3, or 1

Fully Prioritized Interrupt System Controls

In the TL16C450 Mode, Hold and Shift

Registers Eliminate the Need for Precise

Synchronization Between the CPU and

Serial Data

Modem Control Functions (CTS, RTS, DSR,

DTR, RI, and DCD)

Transmitter and Receiver Run at the Same

Speed

Programmable Baud Rate Generator Allows

Division of Any Input Reference Clock by 1

Up to 16-MHz Clock Rate for Up to 1-Mbaud

Operation for the Internal ACE

to (2 –1) and Generates an Internal 16×

Available in 68-Pin PLCC

Clock

description

The TL16PNP550A 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 TL16PNP550A, 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 16 bytes including three additional bits of error status

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.
