TL16C452FNRG4

具有并行端口但没有 FIFO 的双路 UART 68-PLCC 0 to 70

description

The TL16C451 and TL16C452 provide single- and dual-channel respectively serial interfaces along with a

single Centronix-type parallel-port interface. The serial interfaces provide a serial-to-parallel conversion for data received from a peripheral device or modem and a parallel-to-serial conversion for data transmitted by a CPU. The parallel interface provides a bidirectional parallel data port that fully conforms to the requirements for a Centronix-type printer interface.

Integrates Most Communications CardC Functions From the IBM PC/AT or Compatibles With Single- or Dual-Channel Serial Ports

TL16C451 Consists of One TL16C450 Plus Centronix Printer Interface

TL16C452 Consists of Two TL16C450s Plus a Centronix-Type Printer Interface

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

  – Programmable Baud Ratedc to 256 kbit/s

Fully Double Buffered for Reliable Asynchronous Operation
