If you've been using computers for more than a couple of decades, you've probably used a serial port to attach peripherals like your mouse and modem. Until the USB standard rendered them obsolete in ...

The OXmPCI954 is designed to handle 15-Mbit/s asynchronous and 60-Mbit/s synchronous serial data rates. It integrates four high-performance UART channels, a 3.3-V PCI interface, and a local ...

The R2A20150NP/SA is a CMOS 8-bit I/O expander, which has serial to parallel and parallel to serial data converting functions. It can communicate with a microcontroller via few wiring thanks to the ...

The PCA9564 is an integrated circuit designed in CMOS technology that serves as an interface between most standard parallel-bus microcontrollers/microprocessors and ...

This is just a general question. I know, obviously, that there are RS-232 "serial ports" and IEEE 1284/Centronix ports "parallel ports," and that these are "digital" connections. Then you have things ...

This article is part of Now and Then series and part of Electronic Design's 70th Anniversary series. Processors and memory have changed radically over the past 70 years, but the variability of those ...

For a quarter of a century, the USB port has been a faithful old friend. Connecting and powering our everyday gadgets and peripherals, all we've ever needed to do was plug them in and watch it all ...
