82C50A CMOS Asynchronous CMOS Asynchronous The 82C50A Asynchronous Communication Element (ACE) is a high performance programmable Universal Asynchronous Receiver/Transmitter (UART) and Baud Rate Generator (BRG) on a single chip.

Using Intersil’s advanced Scaled SAJI IV CMOS Process, the ACE will support data rates from DC to 625K baud (0-10MHz clock).

The ACE’s receiver circuitry converts start, data, stop, and parity bits into a parallel data word.

The transmitter circuitry converts a parallel
