Sales Briefcase
  • 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 frequency-hopping, 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 battery-powered 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 end-products 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.
