RS1-56R0-J1 Datasheet
Description The UM82C451 is an enhanced version of the popular UM82C450 asynchronaus communications element (ACE). The sarial channel performs serial-to-parallel conversion on data characters received from peripheral devices or modems, and parallel-to-serial conversion of data char- acters transmitted b',t the CPU. The complete status of the Parallel/Asychronous Communlcations Element (P/ACE) can be read at an'/ time during functional operation by the CPU, The information obtained includes the type and condition of the transfer operations being performed, and error conditions. It is fully pin-and upward-compatible with the dual serial channel UM82C452. The second serial channel of the UM82C452 0ccupies pins that are VCC, GND, or NC {not connected) on the UM82C451.
