Abstract :
A flexible RFID tag communicates using UHF RF signals at 915MHz, consists of an 8b CPU, and employs a DES and anti-side channel attack routine in firmware. The tag realizes stable clock generation by a digital control clock generator, and occupies an area of 10.5 times 8.9mm2, is 145mum thick, consumes 0.54mW at 1.5V supply, and communicates with a maximum range of 43cm at a power of 9dBm.
