The PI90LV017AWEX is an integrated interface device. It incorporates an RS-485 transceiver and PCA9554A intelligent-buses or devices. This chip can be used in many different applications due to its versatile design. In this article, we will focus on the common application field of the PI90LV017AWEX, as well as its working principle.

The PI90LV017AWEX is commonly used for interfacing microcontrollers to personal computers, due to its compatibility with the USB and RS-232 bus. It has also been used for interfacing industrial control equipment, where its RS-485 transceiver provides an industrial-grade control protocol. Additionally, the PI90LV017AWEX can be used to convert analogue signals into digital signals and vice versa, allowing it to be used in applications such as motor control, pulse-width-modulation, and analogue-to-digital conversions. It can also be used for remote telemetry and communication, with an integrated feature to support asynchronous-serial-data transmission.

In terms of its working principle, the PI90LV017AWEX operates using its integrated PCA9554A controller. This controller is capable of switching levels between the device being interfaced and the host computer. It can also control the respective operating modes of the PCA9554A and the RS-485 transceiver. The PCA9554A controller controls the state of the interface, e.g. by controlling the voltage levels, increasing and decreasing the frequency, and other parameters.

The PI90LV017AWEX also incorporates a RS-485 transceiver circuit, which provides an industrial-grade control protocol. This transceiver converts the signals being received into level-compatible signals and then sends them through the RS-485 connector. This allows the device to transmit and/or receive data, depending on the application. The device also has a separate directional pin that is used to select the direction of communication, i.e. the device will either transmit or receive the data.

To sum up, the PI90LV017AWEX is an integrated interface device. It incorporates an RS-485 transceiver and PCA9554A, allowing it to be used in many different applications. It is commonly used for interfacing microcontrollers to personal computers or industrial control equipment. Moreover, it is able to convert analogue signals into digital signals and vice versa, as well as provide asynchronous-serial-data transmission. The PI90LV017AWEX also operates using its integrated PCA9554A controller and includes a RS-485 transceiver circuit.
