Product overview

Description

The ST25R3916B, ST25R3917B, and ST25R3919B (hereafter referred to as ST25R39xxB) are high-performance NFC universal devices. They support NFC initiator, NFC target, NFC reader, and NFC card emulation modes when applicable.

Designed to be compliant with EMVCo 3.1a analog and digital, these devices are optimized for POS terminal applications. They enable fast EMVCo certification cycles, even under harsh conditions, with antenna around noisy LCD displays.

The ST25R3916B device includes an advanced analog front end (AFE) and a highly integrated data framing system for ISO18092 passive and active initiator, ISO18092 passive and active target, NFC-A/B (ISO14443A/B) reader including higher bit rates, NFC-F (FeliCa™) reader, NFC-V (ISO15693) reader up to 53 kbps, and NFC-A / NFC-F card emulation. The ST25R3917B and ST25R3919B provides a reduced feature set compared to the ST25R3916B.

Special stream and transparent modes of the AFE and framing system is used to implement other custom protocols in reader or card emulation mode.

The ST25R39xxB feature high RF output power to directly drive antennas at high efficiency.

The ST25R39xxB include additional features, making them incomparable for low-power applications. The presence of a card is detected by performing a measurement of the amplitude or phase of the antenna signal. They also contain a low power RC oscillator and wake-up timer to automatically wake-up the ST25R39xxB after a selected time period and check for a presence of a tag using one or more techniques of low power detection of card presence (phase or amplitude).

The ST25R39xxB are designed to operate from a wide power supply range (2.6 to 5.5 V from -40 °C to +105 °C, 2.4 to 5.5 V from -20 °C to +105 °C), and a wide peripheral IO voltage range (from 1.65 to 5.5 V).

Due to this combination of high RF output power, low-power modes and wide supply range these devices are perfectly suited for infrastructure NFC applications.
