Description

The MLX90108 is a dedicated 64 bit Read Only

(RO) Transponder (TAG). Clock and power

supply are taken from the electromagnetic field.

By switching a resistor in parallel to the resonant

circuit formed by the integrated tuning capacitor

and the external coil, the transponder amplitude

modulates the electromagnetic field. Encoding of

the data and data rate depend on the version.

It is a low cost solution for high volume

applications. The tuning and buffer capacitors are

integrated on chip. Operating frequency (SRF)

range is [100; 150]kHz.

The unique identification code (ID) is EEPROM

programmed in test mode during probing. Data

coding and data rate are mask programmed. An

optimized layout for gold bumps and a standard

version are available for all options. This allows

the device to be integrated into any assembly

form.
