ST25RU3993BQFT

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 batterypowered equipment such as mobile phones.
Packaged in a 7×7 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.
