Product overview

Description

The ST25RU3993 RAIN® (UHF) RFID reader device provides multi-protocol support for the 840-960 MHz UHF band compatible with ISO18000-62 & -63, ISO29143 and to GS1’s EPC UHF Gen2 air interface protocol. 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.
