CDP6402 General Description


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.

The data word can be 5, 6, 7 or 8 bits in length. Parity may be odd, even or inhibited. Stop bits can be 1, 1-1/2, or 2 when transmitting 5-bit code).

The CDP6402 and CDP6402C can be used in a wide range of applications including modems, printers, peripherals, video terminals, remote data acquisition systems, and serial data links for distributed processing systems.

The CDP6402 and CDP6402C are functionally identical. They differ in that the CDP6402 has a recommended operating voltage range of 4V to 10.5V, and the CDP6402C has a recommended operating voltage range of 4V to 6.5V.
