Programmable Auto-RTS and Auto-CTS
In Auto-CTS Mode, 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 24-MHz Clock Rate for up to 1.5-Mbaud OperaTIon With VCC = 5 V
Up to 20-MHz Clock Rate for up to 1.25-Mbaud OperaTIon With VCC = 3.3 V
Up to 48-MHz Clock Rate for up to 3-Mbaud Operation with VCC = 3.3 V (ZQS Package Only, Divisor = 1)
Up to 40-MHz Clock Rate for up to 2.5-Mbaud Operation with VCC = 3.3 V (ZQS Package Only, Divisor ≥ 2)
Up to 16-MHz Clock Rate for up to 1-Mbaud Operation With VCC = 2.5 V
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, and 2.5-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
