N82050

The N82050 is a kind of asynchronous communications controller which is low cost,higher performance alternative to the INS 16450. N82050  provides a low cost ,high-performance integrated modem solution when combined with Intel's 89024 modem chip set.Its 28-laed package provides all the functionality necessary for an IBM PC environment while substantially decreasing board space requirements.

There are some information about N82050's features.(1) programmable,16-bit baud rate generator; (2) system clock; (3) 28-lead DIP and PLCC package; (4) no-TTL interface to most Intel processors; (5) complete interrupt and status reporting; (6) line break and detection; (7) internal diagnostics with local loopback.
