It includes an on-chip VCO and a power amplifier, and offers a plete 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 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 promised 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 plete RFID reader system, thus eliminating the need for a plex RFID co-processor.
