STMicroelectronics’ ST25R3916B-AQWT and ST25R3917B-AQWT NFC Forum Reader devices combine high output power and energy efficiency at a competitive price. Supporting NFC initiator, target, reader, and card-emulation modes, they can be used in contactless-payment, device-pairing, wireless-charging, brand protection, and other industrial and consumer applications.
The new devices introduce improved active wave shaping (AWS) with increased flexibility that simplifies adjustment of the RF output to optimize overshoot and undershoot.
The ST25R3916B and the ST25R3917B deliver up to 1.6W RF output power and can drive antennas directly at high efficiency. Dynamic power-output (DPO) adjustment enables designers to keep the radiated power between the upper and lower limits defined by EMVCo and the NFC Forum specifications.
