HD-6402/883
TM
CMOS Universal Asynchronous
Receiver Transmitter (UART)
March 1997
Features
Description
• This Circuit is Processed in Accordance to MIL-STD883 and is Fully Conformant Under the Provisions of
Paragraph 1.2.1.
The HD-6402/883 is a CMOS UART for interfacing computers or microprocessors to an asynchronous serial data channel. 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 transmitting 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
• CMOS/TTL Compatible Inputs
The HD-6402/883 can be used in a wide range of applications including modems, printers, peripherals and remote
data acquisition systems. Utilizing the Intersil advanced
scaled SAJI IV CMOS process permits operation clock frequencies 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.
