Implementation of standard and custom protocols like MIFARE™ Classic is possible using the AFE and implementing framing in the external microcontroller (Stream and Transparent modes). The ST25R3911B is positioned perfectly for the infrastructure side of the NFC system, where users need optimal RF performance and flexibility combined with low power. Thanks to automatic antenna tuning (AAT) technology, the device is optimized for applications with directly driven antennas. The ST25R3911B is alone in the domain of HF reader ICs as it contains two differential low impedance (1 Ohm) antenna drivers. The ST25R3911B includes several features that make it very suited for low power applications. It contains a low power capacitive sensor that can be used to detect the presence of a card without switching on the reader field.\u003c\/p\u003e\u003ch5\u003eTechnical data\u003c\/h5\u003e\n        \u003ctable border=\"1\" cellpadding=\"5\" cellspacing=\"0\"\u003e\n          \u003cthead\u003e\n            \u003ctr\u003e\n              \u003cth\u003eCharacteristic\u003c\/th\u003e\n              \u003cth\u003eValue\u003c\/th\u003e\n            \u003c\/tr\u003e\n          \u003c\/thead\u003e\n          \u003ctbody\u003e\n        \u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eRF Transceiver\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSub Type\u003c\/td\u003e\n\u003ctd\u003eTransceiver\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModulation Technique\u003c\/td\u003e\n\u003ctd\u003eAM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePackage Type\u003c\/td\u003e\n\u003ctd\u003eQFN\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePin Count\u003c\/td\u003e\n\u003ctd\u003e32\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMount Type\u003c\/td\u003e\n\u003ctd\u003eSurface\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInterface Type\u003c\/td\u003e\n\u003ctd\u003eSPI\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Band 1 Frequency\u003c\/td\u003e\n\u003ctd\u003e27.12MHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMinimum Supply Voltage\u003c\/td\u003e\n\u003ctd\u003e2.4V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Supply Voltage\u003c\/td\u003e\n\u003ctd\u003e5.5V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMinimum Operating Temperature\u003c\/td\u003e\n\u003ctd\u003e-40°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Operating Temperature\u003c\/td\u003e\n\u003ctd\u003e125°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeight\u003c\/td\u003e\n\u003ctd\u003e950μm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLength\u003c\/td\u003e\n\u003ctd\u003e5mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStandards\/Approvals\u003c\/td\u003e\n\u003ctd\u003eNo\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth\u003c\/td\u003e\n\u003ctd\u003e5mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSeries\u003c\/td\u003e\n\u003ctd\u003eST25R3911B\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of Operating Bands\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAutomotive Standard\u003c\/td\u003e\n\u003ctd\u003eNo\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch5\u003eDatasheet\u003c\/h5\u003e\u003cul\u003e\u003cli\u003e\u003ca href=\"https:\/\/docs.rs-online.com\/0c5f\/A700000006628519.pdf\" target=\"_blank\" rel=\"noopener\"\u003eST25R3911B-AQFT Datasheet\u003c\/a\u003e\u003c\/li\u003e\u003c\/ul\u003e\u003ch5\u003eManufacturer\u003c\/h5\u003e\u003cp\u003eSTMicroelectronics\u003c\/p\u003e\u003ch5\u003eWeight\u003c\/h5\u003e\u003cp\u003e0.200 G\u003c\/p\u003e\u003ch5\u003ePack Size\u003c\/h5\u003e\u003cp\u003e1 reel = 4000 units\u003c\/p\u003e\u003ch5\u003eBase Unit of Measure\u003c\/h5\u003e\u003cp\u003ePCE\u003c\/p\u003e\u003ch5\u003eShipping\u003c\/h5\u003e\u003cp\u003e2–3 days within Germany \/ 3–6 days within EU\u003c\/p\u003e","brand":"RS","offers":[{"title":"Default Title","offer_id":46899115491573,"sku":"196-2004","price":14940.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0701\/3220\/3765\/files\/rs_86f8cc90-fcb4-4de2-b37b-741bb5b09e48.png?v=1753981622","url":"https:\/\/shop.ems-yacht.com\/products\/stmicroelectronics-hf-transceiver-am-qfn-32-pin-5-x-5-x-0-95mm-smd","provider":"EMS Yachting","version":"1.0","type":"link"}
