Additional Details

The TMP82C51AP-2 operates from a single +5V power supply. It supports full-duplex communication, allowing simultaneous transmission and reception of data. The programmable baud rate generator permits flexible selection of communication speeds for asynchronous mode. Error detection, including parity, framing, and overrun errors, improves the reliability of data transmission. The modem control signals facilitate interfacing with modems and other communication equipment. The -2 at the end of the part number likely signifies speed grade. It is important to consult the Toshiba datasheet for precise operating characteristics and implementation guidelines.
