MA28151 MA28151 Radiation hard Programmable Communication Interface Replaces Jone 1999 version, DS3574-4.0 DS3574-5.0 January 2000 The MA28151 is based on the industry standard 8251A Universal Synchronous Asynchronous Receiver/Transmitter (USART), modified for data communications with the MAS281 microprocessor. The MA28151 is used as a peripheral device and is programmed by the CPU to operate using virtually any serial data transmission technique presently in use (including IBM “bi-sync”). The USART accepts data characters from the CPU in parallel format and then converts them into a continuous serial data stream for transmission. Simultaneously, it can receive serial data streams and convert them into parallel data characters for the CPU.
