SCN2661 - (SCN2661 / SCN68661) Enhanced programmable communications interface EPCI

General Description

The Philips Semiconductors SCN2661 EPCI is a universal synchronous/asynchronous data communications controller chip that is an enhanced version of the SCN2651.

It interfaces easily to all 8-bit and 16-bit microprocessors and may be used in a polled or interrupt driven system environment.

Key Features

  • Synchronous operation.
  • 5- to 8-bit characters plus parity.
  • Single or double SYN operation.
  • Internal or external character synchronization.
  • Transparent or non-transparent mode.
  • Transparent mode DLE stuffing (Tx) and detection (Rx).
  • Automatic SYN or DLE-SYN insertion SYN, DLE and DLESYN stripping.
  • Odd, even, or no parity.
  • Local or remote maintenance loopback mode.
  • Baud rate: DC to 1Mbps (1X clock) INDEX CO.

Philips Semiconductors Product specification Enhanced programmable communications interface (EPCI) SCN2661/SCN68661 DESCRIPTION The Philips Semiconductors SCN2661 EPCI is a universal synchronous/asynchronous data communications controller chip that is an enhanced version of the SCN2651. It interfaces easily to all 8-bit and 16-bit microprocessors and may be used in a polled or interrupt driven system environment. The SCN2661 accepts programmed instructions from the microprocessor while supporting many serial data communications disciplines —synchronous and asynchronous — in the full- or half-duplex mode. Special support for BISYNC is provided. The EPCI serializes parallel data characters received from the microprocessor for transmission.
