概要
Description
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. The HD-6402/883 can be used in a wide range of applications including modems, printers, peripherals and remote data acquisition systems. Utilizing the Renesas 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.

Tips for Using This Parametric Table:
- Hide Filters button in header: Collapse or expands filters
- Column sort buttons in header: Sort Column alphabetically / numerically descending or ascending
- Reset button in header: Reset all filters to the page default
- Full Screen button in header: Expand the table to full screen view (user must close out of full screen before they can interact with rest of page)
- Export button in header: Export the filtered results of the table to an Excel document
- Filter parts search bar in header: Type to filter table results by part number
- Hide column button in column headers: Select to hide columns in table
- AND / OR toggle switches in header: Toggles the logic of this particular filter to be “AND” or “OR” logic for filtering results
- Multiselect checkboxes at beginning of each row in table: Select these checkboxes to compare products against each other
