Description
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.
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.
