Product Introduction

Overview

The TL16C554AIPNR is an enhanced quadruple version of the TL16C550C asynchronous-communications element (ACE) produced by Texas Instruments. This component is designed to perform serial-to-parallel conversion on data characters received from peripheral devices or modems and parallel-to-serial conversion on data characters transmitted by the CPU. Each channel of the quadruple ACE can be read by the CPU at any time during operation, providing complete status and error condition information.

Key Specifications

Clock Rate Up to 16 MHz
Baud Rate Up to 1 Mbaud
FIFO Size 16 bytes (plus three bits of error data per byte)
Number of Channels 4
Character Length 5-, 6-, 7-, or 8-bit characters
Parity Bit Even-, Odd-, or No-Parity
Stop Bit Generation 1-, 1 1/2-, or 2-Stop Bit

Key Features

  • Integrated Asynchronous-Communications Element with four improved TL16C550C ACEs plus steering logic.
  • In FIFO mode, each ACE transmitter and receiver is buffered with 16-byte FIFOs to reduce CPU interrupts.
  • Programmable baud-rate generators allowing division of any input reference clock by 1 to 2^16 - 1.
  • Full programmability of serial interface characteristics, including character length, parity, and stop bits.
  • False start bit detection, line break generation and detection, and internal diagnostic capabilities.
  • Fully prioritized interrupt system controls and modem control functions (CTS, RTS, DSR, DTR, RI, and DCD).
  • 3-State outputs providing TTL drive capabilities for bidirectional data bus and control bus.
  • Programmable auto-RTS and auto-CTS for efficient serial-data flow control.

Applications

The TL16C554AIPNR is suitable for a variety of applications requiring multiple asynchronous communication channels, such as:

  • Industrial automation systems.
  • Embedded systems requiring serial communication.
  • Modem and serial interface cards.
  • Point-of-sale terminals and other serial communication devices.
  • Network devices and routers.

Q & A

  1. What is the TL16C554AIPNR?
