Description

General part information

ST25R3919B Series

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.
