The Advanced Micro Devices M8251 is a serial I/O controller designed for asynchronous and synchronous serial communication. It supports a variety of communication standards including ASYNC, BIT, SYNC BYTE, BISYNC, and EXT SYNC, with NRZ data encoding. This NMOS device operates over an extended temperature range from -55°C to 125°C and features a CDIP28 package. The M8251 is compatible with the 8080A bus and can operate at clock frequencies up to 2.38 MHz. Its single-channel serial I/O capability and 8-bit external data bus make it suitable for applications in industrial automation and data acquisition systems. The component requires a nominal supply voltage of 5.0V, with a maximum of 5.5V and a minimum of 4.5V, and has a maximum supply current of 80mA.
