XRA00 Overview
The XRA00 is a full-featured, low-cost integrated circuit for use in radio frequency identification (RFID) transponders (tags) operating in the UHF band of frequencies. It is a 128-bit memory, organized as 8 blocks of 16 bits, as shown in Figure 3. When connected to its antenna, operating power is derived from RF energy produced by the RFID reader.
XRA00 Key Features
- 868MHz ISM Band
- 915MHz ISM Band
- Asynchronous 50% to 100% ASK modulation using PWM pulse coding (up to 70 kbit/s)
- Back-scattered answers using Space coding (up to 140 kbit/s) Bi-phase
XRA00 Applications
- SCROLLID: XRA00, matching data, replies by sending back the entire ID Code. This mand is used during the anti-collision sequence
