(5) MC68661PB PROGRAMMABLE COMMUNICATIONS INTERFACE (EPCI),
NOS DIP ICsNew old stock DIP (NOS ICs). The MC 68661PB Programable Communications Interface is a universal synchronous/asynchronous data communications controller IC that is an enhanced version of the Signetics 2651. The 68661 EPCI directly interfaces to most 8-bit MPUs and easily to the TMP68000 MPU, as well as to other 16-bit MPUs. The 68661 may be used in either a polled- or interupt-driven system. Programmed instructions can be accepted from the host MPU while supporting many synchronous or asynchronous serial-data communications protocols in full- or half-duplex mode. And special support for BISYNC is also provided. The 68661 converts parallel data characters, accepted from the µP data bus, into transmit-serial data. Simultaneously, this EPCI can convert receive-serial data to parallel data characters for intput into the µP. Plus other features. LIMITED QUANTITY!
