16550 UART

National Semiconductor later released the A which corrected this issue. This generated high rates of interrupts as transfer speeds increased. This page was last edited on 28 Novemberat Similarly numbered devices, with varying levels of compatibility with the original National Semiconductor part, are made by other manufacturers.


The part was originally made by National Semiconductor.

Not all manufacturers adopted this nomenclature, however, continuing to refer to the fixed chip as a Retrieved from ” https: The C and CF models are okay too, according to this source. The also incorporates a 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 dtaasheet.

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. The current version since by Texas Instruments which bought National Semiconductor is called the D. The original had a bug that prevented this FIFO from being used. Views Read Edit View history.

UART – Wikipedia

The A and newer is pin compatible with the The corrected -A version was released in by National Semiconductor. The A F version was a must-have to use modems with a data transmit rate of baud. Dropouts occurred with The Art of Daatasheet Communication. Technical and de facto standards for wired computer buses.


From Wikipedia, the free encyclopedia. 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. To overcome these shortcomings, the series UARTs incorporated a byte FIFO buffer with a programmable interrupt trigger of 1, 4, 8, or 14 bytes. Pages using web citations with no URL.
