www.DataSheet4U.com The NS16550A UART Design and Application Considerations The NS16550A UART Design and Application Considerations BACKGROUND UARTs like other system components have evolved for many years to become faster more integrated and less expensive The rise in popularity of the personal computer with its focus and competition primarily centered on.

Features

while maintaining software compatibility These development paths have been brought together in a new UART from National Semiconductor designated the NS16550A The NS16550A has all of the registers of its two predecessor parts (INS8250 and NS16450) so it can run all existing IBM PC XT AT RT and compatible serial port software In addition it has a programmable mode which incorporates new high-performance features Of course all of these advanced features are useful in any asynchronous serial communications application regardless of the host architecture The reader is assumed to be familiar with th.
