The Am8251/9551 is a programmable serial data communication interface that provides a Universal Synchronous/Asynchronous Receiver/Transmitter (USART) function_ It is normally used as a peripheral device for an associated processor, and may be programmed by the processor to operate in a variety of standard serial communication formats.
The device accepts parallel data from the CPU, formats and serializes the information based on its current operating mode, and then transmits the data as a serial bit stream.
Simultaneously, serial data can be received, converted into parallel form, de-formated, and then presented to the CPU.
Am8251 • Am9551 Programmable Communications Interface DISTINCTIVE CHARACTERISTICS • Improved performance with Am9551 • Separate control and transmit register input buffers • 8080A/9080A compatible • Synchronous or.
