description

The TL16C750 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 TL16C750, 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.

Pin-to-Pin Compatible With the Existing TL16C550B/C

Programmable 16- or 64-Byte FIFOs to Reduce CPU Interrupts

Programmable Auto-RTSand Auto-CTS

In Auto-CTSMode, CTS Controls Transmitter

In Auto-RTSMode, Receiver 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 or Deleted to or From the Serial Data Stream

5-V and 3-V Operation

Register Selectable Sleep Mode and Low-Power Mode

Independent Receiver Clock Input

Independently Controlled Transmit, Receive, Line Status, and Data Set Interrupts

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 Mbits Per Second

False Start Bit Detection
