HD-6402/883

CMOS Universal Asynchronous

Receiver Transmitter (UART)

March 1997

Features

Description

• This Circuit is Processed in Accordance to MIL-STD-

883 and is Fully Conformant Under the Provisions of

Paragraph 1.2.1.

The HD-6402/883 is a CMOS UART for interfacing comput-

ers or microprocessors to an asynchronous serial data chan-

nel. The receiver converts serial start, data, parity and stop

bits. The transmitter converts parallel data into serial form

and automatically adds start, parity and stop bits. The data

word length can be 5, 6, 7 or 8 bits. Parity may be odd or

even. Parity checking and generation can be inhibited. The

stop bits may be one or two or one and one-half when trans-

mitting 5-bit code.

• 8.0MHz Operating Frequency (HD-6402/883B)

• 2.0MHz Operating Frequency (HD-6402/883R)

• Low Power CMOS Design

• Programmable Word Length, Stop Bits and Parity

• Automatic Data Formatting and Status Generation

• Compatible with Industry Standard UARTs

• Single +5V Power Supply

The HD-6402/883 can be used in a wide range of applica-

tions including modems, printers, peripherals and remote

data acquisition systems. Utilizing the Harris advanced

scaled SAJI IV CMOS process permits operation clock fre-

quencies up to 8.0MHz (500K Baud). Power requirements,

by comparison, are reduced from 300mW to 10mW. Status

logic increases ﬂexibility and simpliﬁes the user interface.

• CMOS/TTL Compatible Inputs
