The Advanced Micro Devices 8251A-BXX is a programmable asynchronous and synchronous serial communication controller from the 8251 series. This NMOS device features one serial I/O channel with a maximum data transfer rate of 0.0078125MBps. It supports various communication standards including ASYNC, BIT, SYNC, BYTE, and BISYNC, utilizing NRZ data encoding/decoding. The controller is designed for compatibility with IAPX 86 and IAPX 88 bus architectures and has an 8-bit external data bus. Operating over a wide temperature range of -55°C to 125°C, it requires a nominal supply voltage of 5.0V. The 8251A-BXX is housed in a 28-lead Ceramic Dual In-line Package (CDIP). This component is integral to systems requiring robust serial data transmission, commonly found in industrial automation and legacy computing systems.
