Description
TL16C550C
SLLS177I – MARCH 1994 – REVISED MARCH 2021
TL16C550C Asynchronous Communications Element with Autoflow Control
1 Features
Programmable Auto-RTS and Auto-CTS
In Auto-CTSMode, CTS Controls Transmitter
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
Capable of Running With All Existing TL16C450 Software
After Reset, All Registers Are Identical to the TL16C450 Register Set
Up to 16-MHz Clock Rate for up to 1-Mbaud Operation
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 and 3.3-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 1/2-, or 2-Stop Bit Generation
– Baud Generation (dc to 1 Mbit/s)
False-Start Bit Detection
Complete Status Reporting Capabilities
3-State Output TTL Drive Capabilities for Bidirectional Data Bus and Control Bus
