SCN2681 Datasheet Dual Asynchronous Receiver/transmitter Duart

Manufacturer: Philips Semiconductors (now NXP Semiconductors)

Overview: INTEGRATED CIRCUITS SCN2681 Dual asynchronous receiver/transmitter (DUART) Product specification Supersedes data of 1995 May 01 IC19 Data Handbook 1998 Sep 04 Philips Semiconductors Philips Semiconductors Product.

General Description

The Philips Semiconductors SCN2681 Dual Universal Asynchronous Receiver/Transmitter (DUART) is a single-chip MOS-LSI munications device that provides two independent full-duplex asynchronous receiver/transmitter channels in a single package.

It interfaces directly with microprocessors and may be used in a polled or interrupt driven system.

The operating mode and data format of each channel can be programmed independently.

Key Features

  • Dual full-duplex asynchronous receiver/transmitter.
  • Quadruple buffered receiver data registers.
  • Programmable data format.
  • 5 to 8 data bits plus parity.
  • Odd, even, no parity or force parity.
  • 1, 1.5 or 2 stop bits programmable in 1/16-bit increments.
  • Programmable baud rate for each receiver and transmitter selectable from:.
  • 22 fixed rates: 50 to 115.2k baud.
  • Maximum data transfer: 1X.
  • 1MB/sec, 16X.
