without any dedicated application software. In addition to NDEF support, the ST25TA02K features a 20-bit counter and 128-bit password to protect read / write access to the 2Kbit EEPROM memory. Manufacturers will ship as many as 2.2 billion NFC-enabled smartphones by 2020 according to IHS Technology (Market Insight, NFC-enabled Handset Shipments to Reach Three-Quarters of a Billion in 2015, June 2015). The growing momentum for NFC is expected to drive new IoT and wireless applications in the Smart Home, Smart Healthcare/ Medical, Smart City, and Smart Factory. With ST’s global reach and semiconductor leadership, combined with SAG’s professional manufacturing of RFID tags, the two companies aim to accelerate innovation and new product development that strengthens the competitiveness of their customers’ final products.

They transfer digital signals between circuits in both directions and provide complete galvanic isolation between two power domains, all while using fewer components to save board space. More information about the MAX14933 › More information about the MAX14937 › A schematic is available for download › A hi-res image is available for download › The MAX14933 and MAX14937 are the newest additions to Maxim’s recently introduced ultra-robust portfolio of quad-channel digital isolators, which include MAX14930– MAX14932 and MAX14934– MAX14936. These devices provide best-in-class speed, propagation delay, skew, and jitter for timing sensitive applications while maintaining an extremely robust isolation barrier between two power domains. Digital isolators are replacing optocouplers in many applications because they offer the same isolation capabilities while using less board space and consuming less power. The MAX14933 and MAX14937 provide high voltage isolation of 2.75kVRMS or 5kVRMS, respectively. They support data rates from DC up to 1.7MHz and can be used in isolated I2C busses with or without clock stretching. Both products feature independent 2.25V to 5.5V supplies on each side of the isolator, and provide open- drain channels for applications that require data to be transmitted in

STMicroelectronics and SAG Cooperate to Deliver High-Performance, Tiny NFC Tags for IoT Applications STMicroelectronics (NYSE: STM), a global semiconductor leader serving customers across the spectrumof electronics applications, and Securitag Assembly Group (SAG), a leading supplier of RFID transponders announced a tiny NFC Ferrite Tag that uses STMicroelectronics’ ST25 NFC tag IC for IoT (Internet of Things) data- transmission applications. Small, light, and thin, the NFC Ferrite Tag can be surface– mounted during production through the metal pad that can be directly soldered to the PCB surface. In addition, the NFC Ferrite tag can function when placed on metal products because of its anti-metallic interference characteristics. These features make it highly attractive for IoT data-transmission applications in consumer electronics, wearable devices, and smart healthcare products. The tiny NFC Ferrite Tag perfectly suits the need for smaller, thinner, and lighter design for wearable products where compactness is critical. Along with its small dimensions (4.9 x 3.0 x 2.5 mm), the NFC Ferrite Tag with an embedded antenna demonstrates outstanding RF performance, benefiting from ST’s state-of-the-art ST25TA02K NFC Forum Type 4 tag IC with built-in NDEF (NFCDataExchange Format) message support. This allows the NDEF data to be directly executed through an Android NFC phone

Two-Channel, Bi- Directional Digital Isolators Reduce Space and System Complexity for Designers Designers can save space and achieve more flexible designs with theMAX14933 and MAX14937 two-channel, bi-directional digital isolators from Maxim Integrated Products, Inc. (NASDAQ: MXIM).
