SLWS188–JUNE 2006

1.8-V to 5-V DUAL UART WITH 64-BYTE FIFOS

FEATURES

•

Fully Programmable Serial Interface

Characteristics:

•

Larger FIFOs Reduce CPU Overhead

– 5-, 6-, 7-, or 8-Bit Characters

Programmable Auto-RTS and Auto-CTS

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

and Detection

In Auto-CTS Mode, CTS Controls the

Transmitter

– 1-, 1 ½-, or 2-Stop Bit Generation

– Baud Generation (dc to 1 Mbit/s)

False-Start Bit Detection

•

In Auto-RTS Mode, RCV FIFO Contents, and

Threshold Control RTS

Serial and Modem Control Outputs Drive a

RJ11 Cable Directly When Equipment is on

the Same Power Drop

•

Complete Status Reporting Capabilities

3-State Output TTL Drive Capabilities for

Bidirectional Data Bus and Control Bus

•

Capable of Running With All Existing

TL16C450 Software

•

Line Break Generation and Detection

Internal Diagnostic Capabilities:

After Reset, All Registers Are Identical to the

TL16C450 Register Set

– Loopback Controls for Communications

Link Fault Isolation

Up to 48 MHz Clock Rate for up to 3-Mbps

(standard 16X sampling) Operation, or up to

6-Mbps (optional 8X sampling) Operation

With V_CC= 5 V Nominal

– Break, Parity, Overrun, and Framing Error

Simulation

•

Fully Prioritized Interrupt System Controls

•

Up to 32 MHz Clock Rate for up to 2-Mbps

(standard 16X sampling) Operation, or up to

4-Mbps (optional 8X sampling) Operation

With V_CC= 3.3 V Nominal

Modem Control Functions (CTS, RTS, DSR,

DTR, RI, and DCD)

•

Available in 44-Pin PLCC (FN) or 32-Pin QFN

(RHB) Packages

Up to 24 MHz Clock Rate for up to 1.5-Mbps

(standard 16X sampling) Operation, or up to

3-Mbps (optional 8X sampling) Operation

With V_CC= 2.5 V Nominal

Each UART's Internal Register Set May Be

Written Concurrently to Save Setup Time

Multi-Function Output (MF) Allows Users to

Select Among Several Functions, Saving

Package Pins

Up to 16 MHz Clock Rate for up to 1-Mbps

(standard 16X sampling) Operation, or up to

2-Mbps (optional 8X sampling) Operation

With V_CC= 1.8 V Nominal

APPLICATIONS

•

Point-of-Sale Terminals

Gaming Terminals

Portable Applications

Router Control

Cellular Data

Factory Automation

In the TL16C450 Mode, Hold and Shift

Registers Eliminate the Need for Precise

Synchronization Between the CPU and Serial

Data

•

Programmable Baud Rate Generator Allows

Division of Any Input Reference Clock by 1 to

(2¹⁶- 1) and Generates an Internal 16 × Clock

Standard Asynchronous Communication Bits

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

From the Serial Data Stream

•

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
