1. General description
The UCODE HSL IC, SL3ICS3001 (UCODE High frequency Smart Label) is a dedicated
chip for passive smart tags and labels, especially for supply chain management and
logistics applications in the US, where operating distances of several meters can be
realized. Further, the UCODE HSL technology platform is also designed for operation
under European regulations.
This integrated circuit is the first member of a product family of smart label ICs targeted to
be compliant with the future ISO standards 18000-4 and 18000-6 for item management.
The UCODE HSL system offers the possibility of operating labels simultaneously in the
field of the interrogator antenna (Anticollision, Collision Arbitration).
The UCODE HSL family of ICs is especially designed for long range applications.
The tag requires no internal power supply. Its contactless interface generates the power
supply via the antenna circuit by propagative energy transmission from the interrogator
(read/write device), while the system clock is generated by an on-board oscillator. The
contactless interface demodulates data transmitted from the interrogator to the UCODE
HSL based tag, and further modulates the electromagnetic field provided by the
interrogator for data transmission from the UCODE HSL based tag to the interrogator.
A generic RFID system consists of an interrogator (base station) that runs the RFID
protocol, as well as one or more tags. The tag itself includes an SL3ICS3001 chip and an
antenna tuned to the carrier frequency of the interrogator, and a package to hold the chip
and antenna together.
When placed in the RF field of an interrogator, a SL3ICS3001 based tag will begin to
power up. If the field is strong enough, the tag IC will execute a power-on reset and will be
ready to receive commands. Each command begins with a preamble and start delimiter
that, taken together, enable the tag to perform clock and data recovery on the incoming
signal. Data to and from the tag is checked for errors using a CRC. Therefore, CRC fields
are present in all interrogator commands and in all tag responses. Additional data
protection is provided by Manchester encoding on the forward (interrogator to tag) link
and FM0 encoding on the return (tag to interrogator) link.
The interrogator can perform a number of functions on tags in its field. For example, the
interrogator can send a command sequence, which allows it to identify multiple tags in its
RF field simultaneously. Alternatively, it can select a subset of the tags in the field based
on tag memory contents. It can also read data stored on a tag in its field, as well as write
data to such a tag. In addition, it can simultaneously write data to an arbitrary subset of the
tags in the field.

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.
