Rev. 4817ASRFID09/04
Features
Carrier Frequency f
RF
: UHF (800 - 1000 MHz)
Compliant with Current and Upcoming World-wide Radio Regulations
(FCC Part 15 Subpart C; EN 300 220; Draft EN 302 208-1, SRD Targeting ETSI
Recommendation, Japan)
The IC is Supporting a Data Rate Adaptation Possibility which Enables Optimal Data
Rate Adjustments Considering Different RF Regulations
The Data Rate can be Adjusted Between 5 kbit/s to 80 kbit/s
The Data Rate of the Return Link is Independent of the Data Rate of the Forward
Link
Lowest RF Input Power Requirement Typically 10 W
1344-bit EEPPROM Memory
1024-bit User Memory
320-bit System Memory (128-bit ID Page, 128-bit User System Information,
64-bit Manufacturer Information, etc.)
Programming of Virgin Tags Possible
Single Programming Does not Require Arbitration Selection
Anonymous Read Functions of Non-unique Data Structures
Deterministic (Binary Tree) and Slotted Based Anti-collision Function
Detection Rate, e.g., in Europe up to 460 Tags/s (Based on Synchronous Mode,
Full-duplex, 64 Bit ID + 40 kbit Forward/Return Link)
Mixture of Both Anti-collision Procedures is Possible
For Both Anti-collision Methods, no UID is Required
Pointer Based Anti-collision in Combination with the Tree Walking Possibility
Forward Link (Interrogator to Tag)
DSBM as well as ASK
Adaptive PWM Coding; Supports Adaptive Functionality Based on Close Loop
Concepts (Data Rate, Encoding Adjustments)
Return Link (Tag to Interrogator)
ASK Modulation
PSK Modulation (to Achieve Best SNR, BER and Power Transfer Possibilities, and
Best Performance in Noisy and/or Multi-reader Environments)
4 Kinds of Coding: FM0, Two Kind of NRZI, 3phase1 and Subcarrier
Synchronous and Asynchronous Return Link Protocol
Link Can Be Stopped/Interrupted at Any Time
Full-duplex Link Mechanism (Higher Throughput and Increased Data Robustness)
Supports a Selectable EAS Mechanism
Operating Range of > 4 m (TX Power 500 mW ERP/869 MHz) Possible
Typical Applications
Supply Chain Management
Asset Control
Toll Collection
Pallet Tracking
Gas Cylinder Tracking
Benefits
Meets User Requirements of GTAG
Supports ISO 18000-6 FDIS Data Structures (AFI/ASF, DSFID, UID)
Different UID Structure Handling Possible (such as AutoID Centre ePC)
Derivative and Therefore Compatible to the Open Platform Concept AIDU
1-kbit UHF
R/W IDIC
with
Anti-collision
Function
ATA5590
TAGIDU
