AS3955-AWLM-i4 is one of a series of RFID, RF access, and monitoring ICs from Austria Microsystems. It is designed to operate in harsh environments where high power consumption is not an option. The package includes a chip antenna and a low overall power consumption of 0.65 mA. The chip can detect threats and can be used for asset tracking, access control, and other applications.

The device has a pulse current limit that optimizes protection when employed in RF energy measurement applications. It is designed to work with an input voltage of 1.8V to 3.3V. It also has an integrated lock-out circuit for maximum robustness against RF interference. Additionally, an integrated voltage regulator helps reduce power consumption and a 0.1Ω source switch protects against voltage drops. Furthermore, sleep modes, automatic link ROC, and integrated wake-up functions further reduce power consumption, while allowing fast wake-up times.

The device is designed to operate in the frequency range of 860MHz to 960MHz. Its power consumption of 0.65mA makes it prefect for battery-powered applications. It is quite flexible, as the user has access to a wide selection of full wave rectification, buffer, and circularity features. Furthermore, the device allows the user to set the RF Output Power limit to protect against overcurrent or short circuits.

At its core, the device operates using its AS3955-AWLM-i4 antenna and the low power ASIC radio. The antenna is designed to pick up RF signals from the surrounding environment and transmit the signals using an FM modulation scheme. In addition, the device performs as a transponder, allowing it to detect and respond to radio requests. This makes the device suitable for asset tracking, access control, and other applications.

The device’s low power feature makes it suitable for battery-powered applications, as it brings down the battery drain. This is especially important when operating in harsh environments. The chip’s ability to detect and respond to radio requests gives it an extra layer of security and reliability. Additionally, the device supports a variety of advanced data exchange functions to support applications in asset tracking, access control, and other applications.

Overall, the AS3955-AWLM-i4 is an advanced RFID, RF access, and monitoring IC from Austria Microsystems. It is designed to operate in harsh environments where high power consumption is not a viable option. It employs an antenna and a low overall power consumption of 0.65 mA, allowing it to pick up RF signals and operate as a transponder. The device can be used for asset tracking, access control, and a variety of other applications thanks to its advanced features such as 0.1Ω source switch protection, integrated voltage regulator, sleep modes, automatic link ROC, and integrated wake-up functions.
