16550 UART

The Art of Serial Communication. This generated high rates of interrupts as transfer speeds increased.

Not all manufacturers adopted this nomenclature, however, continuing to refer to the fixed chip as a The also incorporates a transmit FIFO, datasneet this feature is less critical as delays in interrupt service would only result in sub-optimal transmission speeds and not actual data loss.

The corrected -A version was released in by National Semiconductor. To overcome these shortcomings, the series UARTs incorporated a byte FIFO buffer with a programmable interrupt trigger of 1, 4, datssheet, or 14 bytes. Views Read Edit View history.

UART – Wikipedia

This page was last edited on 28 Novemberat Interfaces are listed by their speed in the roughly ascending order, so the interface at the end of each section should be the fastest. 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.

Retrieved from ” https: The current version since by Texas Instruments which bought National Semiconductor is called the D. Pages using web citations with no URL. 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.

Technical and de facto standards for wired computer buses.

The original had a bug that prevented this FIFO from being adtasheet. The part was originally made by National Semiconductor. National Semiconductor later released the A which corrected this issue.


The A F version was a must-have to use modems with a data transmit rate of baud.

Similarly numbered devices, with varying levels of compatibility with the original National Semiconductor part, are made by other manufacturers. From Wikipedia, the free encyclopedia. The C and CF models are okay too, according to this source.

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.
