Brief Description
The ZMD41211 is a fully integrated passive 13.56 MHz ISO15693-compliant transponder IC with an on-chip temperature sensor and wireless initialization capability. With on-chip timer to establish the log time base and EEPROM to log the sensor data during operation, the ZMD41211 is designed to reduce product spoilage while enhancing the degree of automation and safety in logistics and transportation of goods.
The on-chip EEPROM can be written in downlink direction and read in uplink direction by inductive coupling from a reader. The power is also extracted from the reader through inductive coupling. Due to the on-chip tank capacitor, the ZMD41211 only needs an external coil to communicate with a reader unit.
The on-chip timer unit allows the pre-selection of operating start time and log cycle, hence the log scheme is programmable for a variety of applications.
