To dxtasheet these shortcomings, the series UARTs incorporated a byte FIFO buffer with a programmable interrupt trigger of 1, 4, 8, or 14 bytes. 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.

This generated high rates of interrupts as transfer speeds increased. Pages using web citations with no URL. Technical and de 1655a0 standards for wired computer buses.

Exchange of the having only a one-byte received data buffer with aand occasionally patching or 165500a 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.

Similarly numbered devices, with varying levels of compatibility with the original National Semiconductor part, are made by other manufacturers.

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.
