Overview: www.DataSheet4U.com áç FEBRUARY 2004 ST78C36/36A ECP/EPP PARALLEL PRINTER PORT WITH 16-BYTE FIFO REV. 5.0.

General Description

The ST78C36/36A is a monolithic Parallel Port Interface for use with IBM PC compatible platforms.

Operation as a standard Centronics printer port is the default, but software may re-configure the device to support bi-directional IBM PS/2 parallel port, Enhanced Parallel Port (EPP), or the Extended Capabilities Port (ECP , as defined by Hewlett Packard and Microsoft) modes.

The ECP modes are supported by a 16 byte FIFO that may be accessed by programmed I/O or DMA cycles.

Key Features

  • IBM AT bus compatible.
  • Bi-directional port capability.
  • 16 byte FIFO for ECP modes.
  • On-chip oscillator (ST78C36A, ST78C36CQ64).
  • Software selectable Interrupt (5, 7, or 9) and 8-bit DMA channel (ST78C36CQ64) FIGURE 1. ST78C36/36A BLOCK.
