The I/O buffer information specification, or IBIS, is a simulation system that allows the user to model then simulate signal integrity scenarios before committing the circuit to the printed circuit ...

When it comes to ATmega8 basic I/O interfacing, we just learned how to connect a switch as an input device to control one LED connected as an output device. Now a simple tour through selected areas of ...

Part of setting up a microcontroller when writing a piece of firmware usually involves configuring its connections to the outside world. You define a mapping of physical pins to intenral peripherals ...

The integration of analog with digital and the increase number of on-chip features in mixed-signal controllers demand more complex I/O structures. Though they are sometimes some of the most neglected ...

The first program anyone writes for a microcontroller is the blinking LED which involves toggling a general-purpose input/output (GPIO) on and off. Consequently, the same GPIO can be used to read ...

Serial Peripheral Interface (SPI) output driver chips are popular with embedded designers because they provide multiple outputs without using any CPU I/O pins. This article explains how to adapt a ...

Among all the Arduino boards, the Uno is most folks' go-to choice, and for good reason. It's the perfect platform to get started with Arduino, it's capable enough to handle a wide range of tasks, and ...

The 555 timer IC is an integrated circuit (chip) which is used in a variety of timer, delay, pulse generation, and oscillator applications. 555 Signals and Pinout (8 pin DIP) Figure below shows the ...

Nisshinbo Micro Devices has launched the NR1620 series voltage regulator with dual input pins to supply low-power microcontroller cores and other applications. The NR1620 has an output current of ...
