STMicroelectronics has announced the launch of its latest automotive NFC readers, the ST25R500 and ST25R501. These new additions to the ST25R portfolio are designed to enhance user experiences with superior wake-up and detection range capabilities, meeting the stringent requirements of the Car Connectivity Consortium and Wireless Power Consortium.
The ST25R500 and ST25R501 NFC readers deliver market-leading performance with up to 2W peak output power and high receiver sensitivity, offering up to 70% greater interaction range compared to other readers on the market. The ST25R501, housed in a compact 4mm x 4mm QFN package, occupies 36% less PCB area, making it the industry’s most powerful automotive NFC reader with the smallest outline. This makes it ideal for space-constrained applications such as door handle and B-pillar modules.
Both chipsets ensure outstanding RF performance, even with space-constrained antenna designs. They are AEC-Q100 qualified, NFC Forum CR13 compliant, and meet the rigorous standards of car and phone OEMs. In addition to car access and start systems, the ST25R500 and ST25R501 are used in NFC card protection on center-console Qi chargers, phone pairing, and data transfer.
Rene Wutte, head of automotive NFC reader marketing at STMicroelectronics, stated, “The automotive readers we are announcing simplify engineering challenges, allowing product development teams to focus on creating sleek, slim, and stylish designs that enhance the user experience by providing seamless and enjoyable contactless interactions between vehicle owners and their cars.”
The Marquardt Group, a high-tech company specializing in electrical and electronic products for automotive and other markets, is an early adopter of ST’s new devices. Johannes Mattes, globally responsible for access sensors at Marquardt, commented, “Using ST’s latest high-power readers in our new door handle module for digital access control enabled us to complete the design extremely quickly while also significantly boosting performance compared to legacy products.”
The new readers benefit from enhanced noise suppression with very high receiver sensitivity, allowing operation in harsh conditions while simplifying electromagnetic immunity and easing certification. Dynamic power output with active waveshaping control on each power level, along with diagnostics and NFC card protection features, ensure robust performance and safety.
