The Calypso module offers four remote controllable GPIOs. This Pins can be configured as input, output high/low and some of them as PWM. This provides the possibility to perform simple and quick hostless operation. This application note describes how to use and configure this functionality.

The function of a RF (Radio Frequency) transmission line is a directing RF signal from a source to a load with minimal loss and distortion. Impedance plays an important role in signal transmission. Even if the trace impedance already matches, adding a connector can cause an impedance mismatch and thus signal distortions due to reflections. The purpose of this application note is to outline methods for improving signal transmission when a connector is added on a PCB.

PolarFire FPGAs represent the industry's most advanced security programmable FPGAs. Data security protects application data—stored, communicated, or computed at run-time—from being copied, altered, or corrupted.

Due to their superior efficiency, excellent controllability, and higher speed capabilities, brushless DC motors (BLDC) are one of the most widely used DC motors. These characteristics make BLDC suitable for many kinds of applications in a large variety of industries. Nowadays, BLDC motors are nearly everywhere and have a solid role in manufacturing and industrial applications as actuators and in CNC machine tools. Similarly, its efficiency has made it a popular choice for white goods, computer hard drives, electric and hybrid vehicles, and even medical equipment. In the automotive industry, its presence is expected to increase due to the growing number of electromechanical in-vehicle systems, including HVAC systems, fuel and water pumps, anti-lock braking systems (ABS), and power steering systems. This application note explains the main features of brushless DC motors, their control methodology, and how different aspects between BLDC and BDC motors compare.

Integrated load switches are electronic switches used in systems to turn power rails on and off, similar to a relay or a MOSFET. Integrated load switches provide many benefits, including protection features that are too difficult or complex to implement with discrete components.

The I²C bus (Inter-Integrated Circuit) is a popular serial communication interface. It is mainly used to connect microcontrollers with peripheral ICs (e.g. sensors or memory). The bus uses one bidirectional data line (SCL) and one clock line (SDA) each. However, the I²C bus is not only used within circuit boards, but is also extended into other areas in many applications with the aid of various connectors and cables. This makes the I²C bus potentially more susceptible to external interference such as ESD, burst and radiated RF disturbances. The goal of this application note is to show the reader a suitable filter and protection circuit that increases the noise immunity of the I²C bus without sacrificing the signal quality of the data and clock lines. For this purpose, simulation models were created in LTspice and a real application was measured to verify the simulation results.
