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

C

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.
