Description
• Low Power CMOS Circuitry. . . . . . . . . . 7.5mW (Typ) at
The CDP6402 and CDP6402C are silicon gate CMOS
Universal Asynchronous Receiver/Transmitter (UART)
circuits for interfacing computers or microprocessors to
asynchronous serial data channels. They are designed to
provide the necessary formatting and control for interfacing
between serial and parallel data channels. The receiver
converts serial start, data, parity, and stop bits to parallel
data verifying proper code transmission, parity and stop bits.
The transmitter converts parallel data into serial form and
automatically adds start parity and stop bits.
