DESCRIPTION
The Philips Semiconductors SCN2651 PCI is a universal
synchronous/asynchronous data communications controller chip
designed for microcomputer systems. It interfaces directly to the
Philips Semiconductors SCN2650 microprocessor and may be used
in a polled or interrupt driven system environment. The SCN2651
accepts programmed instructions from the microprocessor and
supports many serial data communication disciplines, synchronous
and asynchronous, in the full or half-duplex mode.
The PCI serializes parallel data characters received from the
microprocessor for transmission. Simultaneously, it can receive
serial data and convert it into parallel data characters for input to the
microcomputer.
The SCN2651 contains a baud rate generator which can be
programmed to either accept an external clock or to generate
internal transmit or receive clocks. Sixteen different baud rates can
be selected under program control when operating in the internal
clock mode.
The PCI is constructed using Philips Semiconductors n-channel
silicon gate depletion load technology and is packaged in a 28-pin
DIP.
