STMicroelectronics ST25DV64KC-IE6S3 RFID & NFC Transceiver 8-Pin SO-8N 1.8-5.5V 53kbps ST25DV64KC-IE6S3

STMicroelectronics ST25DV64KC-IE6S3 RFID & NFC Transceiver 8-Pin SO-8N operates with a wide supply voltage range from 1.8 V to 5.5 V and supports dual interface communication through I2C and RF link. Intended for applications requiring contactless identification, this transceiver provides 64-Kbit electrically erasable EEPROM memory, split into flexible and protectable areas accessible through I2C serial bus or ISO/IEC 15693 RF standard.

This device offers a data rate of up to 53 kbps using FSK and ASK modulation techniques and is certified as NFC Forum Type 5 tag, ensuring interoperability in wireless communication systems. With a minimum operating temperature of -40°C and a maximum operating temperature of 85°C, it supports robust industrial and commercial environments.

The chip includes advanced features such as a dedicated GPO pin to signal RF field detection and mailbox message availability, an internal tuning capacitance of 28.5 pF for optimized antenna tuning, and a half-duplex buffer of 256 bytes to expedite the data transfer process between RF and contact worlds. It supports high-speed I2C communication at 1 MHz and programmable multiple byte writes up to 256 bytes per cycle.

The ST25DV64KC-IE6S3 is housed in an SO-8N package, suitable for surface-mount technology, minimizing board space and enabling easy integration into diverse electronic assemblies in industries including manufacturing, inventory management, access control systems, and IoT devices.
