NS16550A, UART Design and Application Considerations

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 an architecture introduced by IBM has driven both UART performance and software compatibility issues As transmission rates have increased t

NS16550A 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 compat
