SCN2661 - NXP

SCN2661 (SCN2661 / SCN68661) Enhanced programmable communications interface EPCI

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 whi.
