More critically, with only a 1-byte buffer there is a genuine risk that a received byte will be overwritten if interrupt service delays occur. The original had a bug that prevented this FIFO from being used. The Art of Serial Communication. This page was last edited on 28 Novemberat The also incorporates a transmit FIFO, though this feature is less datasneet as delays in interrupt service would only result in sub-optimal transmission speeds and not actual data loss.

Exchange of the having only a one-byte received data buffer with aand occasionally patching or a system software to be aware of the FIFO feature of the new chip, improved the reliability and stability of high-speed connections. The A and newer is pin compatible with the The C and CF models are okay too, according to this source. The A F version was a must-have to use modems with a data transmit rate of baud.

At speeds higher than baudowners discovered that the serial ports of the computers were not able to handle a continuous flow of data without losing characters. From Wikipedia, the free encyclopedia. Interfaces are listed by their speed in the roughly ascending order, so the interface at the end of each section should be the fastest.

National Semiconductor later released the A which corrected this issue. Dropouts occurred with The current version since by Texas Instruments which bought National Semiconductor is called the D.

The part was originally made by National Semiconductor. The corrected -A version was released in by National Semiconductor. By using this site, you agree to the Terms of Use and Privacy Policy.
