Retrieved from ” https: The Art of Serial Communication. To overcome these shortcomings, the series UARTs incorporated a byte FIFO buffer with a programmable interrupt trigger of 1, 4, 8, or 14 bytes. Views Read Edit View history.
Technical and de facto standards for wired computer buses. The C and CF models are okay too, according to this source. The also incorporates ddatasheet transmit FIFO, though this feature is less critical as delays in interrupt service would only result in sub-optimal transmission speeds and not actual data loss. From Wikipedia, the free encyclopedia. The corrected -A version was released in by National Semiconductor.

The current version since by Texas Instruments which bought National Semiconductor is called the D. Pages using web citations with no URL.
Interfaces are listed by their speed in the roughly ascending order, so the interface at the end of each section should be the fastest. This generated high rates of interrupts as transfer speeds increased. The original had a bug that prevented this FIFO from being used.
Not all manufacturers adopted this nomenclature, however, continuing to refer to the fixed chip as a The part was originally made by National Semiconductor. Similarly numbered devices, with varying levels of compatibility with the original National Semiconductor part, are made by other manufacturers.
National Semiconductor later released the A which corrected this issue. This page was last edited on 28 Novemberat The A F version was a must-have to use modems with a data transmit rate of baud. The A and newer is pin compatible with the Dropouts occurred with Exchange of the having only a one-byte received data buffer with aand occasionally patching or setting system software to be aware of the FIFO feature of the new chip, improved the reliability and stability of high-speed connections.
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.
