SL13A
Smart Sensory Tag Chip For Unique
Identification, Monitoring and Data
Logging
General Description
The SL13A is a semi-active tag chip optimized for single-cell,
battery-powered smart labels with sensor functionality. It also
supports fully-passive operation without battery. The chip is
ideal for applications using thin and flexible batteries but can
also be powered from the RF field (electromagnetic waves from
an RFID reader).
The chip has a fully integrated temperature sensor with a
nonlinearity of ±0.5ºC. The external sensor interface (S
EXT
) is an
analog input and allows the connection of an external sensor.
