FN2956.3
CMOS Universal Asynchronous
Receiver Transmitter (UART)
The HD-6402 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.
The HD-6402 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.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free
material sets; molding compounds/die attach materials and 100%
matte tin plate termination finish, which are RoHS compliant and
compatible with both SnPb and Pb-free soldering operations. Intersil
Pb-free products are MSL classified at Pb-free peak reflow
temperatures that meet or exceed the Pb-free requirements of
IPC/JEDEC J STD-020.
*Pb-free PDIPs can be used for through hole wave solder processing
only. They are not intended for use in Reflow solder processing
applications.
