ST25RU3993-BQFT Product Details
The ST25RU3993 is an EPC Class 1 Gen 2 RFID reader IC that implements all the relevant protocols, including ISO 18000-6C, the ISO 29143 air-interface protocol for mobile RFID interrogators, and ISO 18000-6A/B for operation in direct mode. It includes an on-chip VCO and a power amplifier, and offers a complete set of RFID features including Dense Reader Mode (DRM) functionality and support for frequencyhopping, low-level transmission coding, low-level decode, data framing and CRC checking.
The ST25RU3993 operates at very low-power, making it suitable for use in portable and batterypowered equipment such as mobile phones.
Packaged in a 7x7 mm QFN, the ST25RU3993 is able to deliver very high sensitivity and provides high immunity against the effects of antenna reflection and self-jamming. This is critical in mobile and embedded applications, in which antenna design is often compromised by cost or size constraints. High sensitivity enables the endproducts to achieve their required read range while using a simpler and cheaper antenna, thus reducing overall system cost.
Thanks to its high level of integration, the ST25RU3993 requires only an external 8-bit microcontroller to create a complete RFID reader system, thus eliminating the need for a complex RFID co-processor.
