UHF RFID reader IC with programmable dense reader mode

Austriamicrosystems has introduced the AS3992, a new "Simply Gen 2" UHF RFID Reader IC with an integrated analog frontend that provides protocol handling for ISO180006c/b 900MHz RFID reader systems. The AS3992 equipped with multiple built-in programming options, the device is suitable for a wide range of UHF RFID applications.

The key features of the AS3992 IC are,

Full DRM compliance on chip allowing a true World Wide Shippable device
Improved receive sensitivity to -86dBm
On chip pre-distortion meaning improved external PA efficiency
Parallel 8-bit or serial 4-pin SPI interface to MCU using 24 bytes FIFO
Voltage range for communication to MCU between 1.8V and 5.5V
Selectable clock output for MCU
Integrated supply voltage regulator (20mA), which can be used to supply MCU and other external circuitry
Integrated supply voltage regulator for the RF output stage, providing rejection to supply noise
Internal power amplifier (20dBm) for short range applications
Adjustable ASK modulation index
Frequency hopping support
On-board VCO and PLL covering complete RFID frequency range 840MHz to 960MHz
Oscillator using 20MHz crystal
Power down, standby and active mode, Can be powered by USB with no need for step conversion
The suggested applications for the AS3992 IC include fixed readers, portals, car access,
hand held's and embeddable applications.

"Austriamicrosystems continues to expand what is already the industry's largest portfolio of UHF RFID Reader ICs, while setting new performance standards," affirms Bruce Ulrich Director of Marketing Consumer & Communications. "As the market leader in this product area, we will continue to define performance standards to power new embedded applications."
