EM4469 Product details

Description

EM4469 is a CMOS integrated circuit intended for use in electronic Read/Write RF transponders.

The IC is powered by picking the energy from a continuous 125 kHz magnetic field via an external coil, which together with the integrated capacitor form a resonant circuit.
