The Universal Device uses Active Wave Shaping (AWS) to manage energy continuously to improve waveform robustness versus antenna detuning. Together with ST’s Dynamic Power Output (DPO), AWS helps new designs pass EMVCo 3.0 certification faster, easing the tests performed with dissimilar-reference Proximity Integrated Circuit Cards (PICCs) that emulate card, wearable, and mobile devices.
The STR25R3916 features what the company claims is the first Noise-Suppression Receiver (NSR) on the market for this type of device. NSR brings higher sensitivity and prevents the terminal mistaking noise from its own LCD as a load-modulation signal from the payment device, freeing designers from having to use shielded low-noise LCDs in designs. ST25R3916 also delivers up to 1.6W output power, through the internal LDO, or higher with an additional external regulator, ensuring adequate field strength to connect reliably even in setups with small antennas.
Automatic Antenna Tuning (AAT), automatic EMD (Electro Magnetic Disturbance) handling, power-saving capacitive and inductive wake-up (CWU), and support for reader/writer, peer-to-peer, and card-emulation modes are integrated features of the ST25R3916.
A free software tool allows access to the registers and features of the ST25R3916 and offers a complete RF/NFC abstraction (RFAL) for all major technologies including complete ISO-DEP and NFC-DEP layers, covering the whole ST25R product series. A free EMVCo L1 software package is also available.
