Manufacturer: Philips Semiconductors (now NXP Semiconductors)

Overview: INTEGRATED CIRCUITS SCN68681 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 SCN68681 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 is patible with other S68000 family devices, and can also interface easily with other microprocessors.

The DUART can be used in polled or interrupt driven systems.

Key Features

  • S68000 bus compatible.
  • 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.
  • Maximum data transfer rates: 1X - 1MB/sec, 16X - 125kB/sec.
  • Programmable baud rate for each receiver and transmitter selectable from:.
