Frequently Asked Questions
Which NFC and RFID protocols does the ST25R3916-AQFT support?
The ST25R3916-AQFT supports ISO 14443 A and B, ISO 15693, ISO 18092 (NFC IP-1), and NFC Forum tag types 1 through 5. It operates at 13.56 MHz carrier frequency with data rates up to 848 kbps, enabling compatibility with a broad range of contactless cards and tags in a single device.
What supply voltage and current consumption does the ST25R3916-AQFT require for portable reader designs?
The ST25R3916-AQFT operates from a 3.3 V supply rail with a typical active current of approximately 75 mA during transmission. It offers low-power wake-up modes drawing under 5 µA, making it suitable for battery-operated portable NFC readers where power efficiency is a design priority.
How does the ST25R3916-AQFT compare with lower-cost NFC reader ICs when EMVCo compliance is required?
Unlike basic NFC reader ICs limited to ISO 14443 A only, the ST25R3916-AQFT integrates EMVCo-certified analog front end with amplitude and phase demodulation, supporting all EMV payment card variants. This integration eliminates external tuning components and reduces BOM count, justifying its premium over single-protocol alternatives in payment terminal designs targeting EMVCo Level 1 certification.
What package does the ST25R3916-AQFT use and what are the PCB footprint dimensions?
The ST25R3916-AQFT comes in a 32-pin QFN (Quad Flat No-Lead) package with a 5 mm x 5 mm body and 0.5 mm pin pitch. This compact footprint with exposed thermal pad enables dense PCB layouts while providing good thermal dissipation for reader applications requiring continuous operation.
