Western Digital WD1931
The WD1931 is a MOS/LSI device which performs the functions of interfacing a serial data communications channel to a parallel digital system. This pin out allows the user to implement a one-board multiprotocol design. For character-oriented asynchronous and/or synchronous (bi-sync) protocols, the WD1931 is used, and for bit-oriented SOLe, HDLC and ADCCP protocols the WD1933 is used (see WD1933 data sheet).| Part No. | WD1931 |
