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.

FEATURES
 • IBM AT bus compatible
 • Bi-directional port capability
 • 16 byte FIFO for ECP modes
 • On-chip oscillator (ST78C36A, ST78C36Q64)
 • Software selectable Interrupt (5, 7, or 9) and 8-bit DMA channel (ST78C36CQ64)

APPLICATIONS
 • Printers, Scanners and other peripherals
 • ZIP Drives and back up drives
 • Printer Server
 • Embedded Applications
