ST25DV64K-JFR6D3

ST25DV64K-JFR6D3 is a dynamic NFC/RFID tag IC with fast transfer mode capability. This device features two interfaces: the first one is an I²C serial link that can be operated from a DC power supply, and the second one is an RF link activated when the device acts as a contactless memory powered by the received carrier electromagnetic wave. This device offers a fast transfer mode between the RF and contact worlds, thanks to a 256bytes volatile buffer (also called Mailbox). In addition, the GPO pin provides data about incoming events, like RF field detection, RF activity in progress, or mailbox message availability. An energy harvesting feature is also available when external conditions make it possible. It supports all ISO/IEC 15693 modulations, coding, sub-carrier modes, and data rates. It features an interruption pin configurable on multiple RF events (field change, memory write, activity, Fast Transfer end, user set/reset/pulse).
