Philips Semiconductors  
Product specification  
Enhanced programmable communications  
interface (EPCI)  
SCN2661/SCN68661  
DESCRIPTION  
PIN CONFIGURATIONS  
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. Simultaneously, it can receive  
serial data and convert it into parallel data characters for input to the  
microcomputer.

The SCN2661 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. Each version of the EPCI (A, B, C) has a different set  
of baud rates.
