AS3980 UHF RFID Single Chip Reader EPC Class1 Gen2 The AS3980 is an UHF RFID reader IC enabling battery-powered, small form-factor handheld and embedded UHF reader systems for a single tag environment of EPC Class1 Gen2 compliant UHF RFID tags. The device directly supports ISO 18000-6C/ EPC Class1 Gen2 transponders in a single-tag environment. The AS3980 operates at very low power, which means that this advanced RFID reader IC is suitable for use in portable and battery-powered equipment such as mobile phones. AS3980 requires only an external simple 8-bit uC to create a complete RFID reader system. AS3980 is highly integrated and implements the RFID functions on chip thus eliminating a need for a complex RFID co-processor. Packaged in a 7 x 7 mm QFN outline, the IC benefits from fabrication process technology unique to ams to deliver very high sensitivity and providing high immunity to the effects of antenna reflections 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 end-product designs to achieve their required read range while using a simpler and cheaper antenna, thus reducing system bill-of-materials cost.
