EM4200 128 bit Read Only Low Frequency Contactless Identifcation Device
General Description
EM4200 is a CMOS integrated circuit intended for use in electronic
Read Only RF transponders. It is designed to replace directly the
EM Microelectronic-Marin Read Only ICs EM4100/4102 and
EM4005/4105.
The circuit is powered by an external coil placed in an
electromagnetic feld and gets its master clock from the same feld.
By turning on and off the modulation current, the chip sends back
the unique code contained in a factory pre-programmed laser ROM.
The 128 bit unique code is stored in laser programmed ROM. Several
options are available to use 64, 96 or 128 bits of ROM.
The IC offers also different resonant capacitor versions, selectable
by mask option (0pF, 75pF and 250pF) providing the same reading
performances to ensure seamless replacement.
