The Intel C8251A is a programmable communications interface controller in the C8251 series. This NMOS device features one serial I/O channel supporting synchronous and byte-oriented asynchronous communication standards with NRZ data encoding. It operates with a maximum data transfer rate of 0.0078125 MBps and a clock frequency up to 3.125 MHz. The C8251A is compatible with MCS 48, MCS 80, MCS 85, IAPX 86, and IAPX 88 bus architectures, and includes modem control inputs that are selectable as I/O. This component is housed in a 28-lead ceramic dual in-line package (CDIP) with a rectangular shape and through-hole terminal form. It is designed for operation within an industrial temperature range of 0°C to 70°C and requires a supply voltage of 5.0V (nominal). Applications include data acquisition systems, industrial control, and embedded systems requiring serial data communication.
