Similarly numbered devices, with varying levels of compatibility with the original National Semiconductor part, are made by other manufacturers. 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 A F version was a must-have to use modems with a data transmit rate of baud.

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. Retrieved from ” https: Not all manufacturers adopted this nomenclature, however, continuing to refer to the fixed chip as a National Semiconductor later released the A which corrected this issue.

16550 UART

The current version since by Texas Instruments which bought National Semiconductor is called the D. At speeds higher 16f550 baudowners discovered that the serial ports of the computers were not able to handle a continuous flow of data without losing characters.

Interfaces are listed by their speed in the roughly ascending order, so the interface at the end of each section should be the fastest. 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. The original had a bug that prevented this FIFO from being used.
