RFID reader ICs offer -90dBm sensitivity for reliable reading of Gen 2 RFID tags
April 05, 2012 // Julien Happich
The AS3993 and AS3980 from austriamicrosystems offer -90dBm sensitivity and high immunity to self-jamming to ensure reliable reading of Gen 2 RFID tags even in noisy environments.
The AS3993 is an EPC Class 1 Gen 2 RFID reader IC which 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). Highly integrated – it includes an on-chip VCO and power amplifier – it offers a complete set of RFID features including Dense Reader Mode functionality and support for frequency-hopping, low-level transmission coding, low-level decode, data framing and CRC checking.
The AS3980, a sister device to the AS3993, is also an EPC Class 1 Gen 2 RFID reader IC which offers a high level of integration and RF performance. But by removing certain functions, such as support for Dense Reader Mode and Direct Mode, austriamicrosystems has produced a device which is perfectly suited to cost-constrained consumer applications such as the authentication of branded consumables.
Both the AS3993 and AS3980 operate at very low power, typically drawing just 75mA on a supply voltage of 3.3V. This means that these advanced RFID reader ICs are suitable for use in portable and battery-powered equipment such as mobile phones. Packaged in a 7x7mm QFN outline, the ICs can be used in a stand-alone end product, only requiring the addition of a simple 8-bit microcontroller to create a complete RFID reader system. Because they are highly integrated and implement the required RFID functions on-chip, they can also be used alongside an embedded processor, the low processing overhead meaning that an RFID co-processor is not necessary.
