The ZMD41211 is a fully integrated, 13.56 MHz, ISO15693-
compliant passive transponder IC with an on-chip temperature sensor and wireless initialization capability. With on-chip
temperature sensor, and EEPROM for time and temperature
logging, the ZMD41211 is designed to increase the degree of
automation and safety in logistics and transportation of perishable goods or produce.
When inserted into a electromagnetic field, inductive coupling
provides the energy to power the IC. The on-chip EEPROM can
be both written and read based on the energy derived from
the reader by inductive coupling.
The ZMD41211 was designed with low component count in
mind. Due to the on-chip tank capacitor, the ZMD41211 only
requires one external coil to communicate with a reader unit.
The additional I2C bus connection allows adding an external
sensor to the ZMD41211.
The on-chip timer can be programmed for pre-selection of
operating start time and log cycle, hence the log schemecan
be modified for a variety of applications.
