SL3ICS3001

UCODE HSL

Signals enter the chip through the RF front end, where both tag power and the modulation

envelope are recovered. Tag power is regulated and bias voltages are generated in one

part of the analog section. In another part of the analog section, the modulation envelope

is applied to a clock and data recovery circuit. In the case of a valid command, the first

part of the input signal is the preamble and start delimiter, which will be followed by a

specific tag command and any additional fields that command may require. All valid digital

data is processed in the digital section data path, which is controlled by the digital control

module. If a read or write is to be executed, the EEPROM block will be accessed. If data is

to be sent from the tag to the interrogator in response to the command, the digital section

sends the output pattern back to the RF front end, where the impedance modulation that

constitutes backscatter is executed.

Features and benefits

2.1 RF interface features

 Contactless transmission of data and supply energy (no battery needed)

 Operating distance, depending on antenna geometry and local regulations, up to

8.4 m for a single antenna

 Operating frequency within the released operating bands from 860 MHz to 960 MHz

and from 2.4 GHz to 2.5 GHz

 High data integrity: 16 bit CRC, framing

 True anticollision for collision arbitration

 Write distance is 70% of reading distance

2.2 Memory features

 2048 bits including lock bits

 64 bits UID in memory bytes 0 to 7

 216 bytes with user definable access conditions for memory bytes 8 to 223

2.3 Security features

 Unique serial number for each device

 Lock mechanism (write protection) for each byte

2.4 Operating distances features

RFID tags based on the SL3ICS3001 silicon may achieve operating distances according

the following formula:

PTAG ... minimum required RF power for the tag

GTAG ... Gain of the tag antenna

EIRP ... Transmitted RF power
