DESCRIPTION
This device is manufactured in the SAMES 1.2µm N-well
Data is read at the RF interface by means of the on-chip
EEPROM process. It has 64 bits, factory pre-
modulator. The stored bits are clocked out sequentially
programmed and locked in EEPROM memory. Read

provided which allows the device to start reading out data
at low voltages for improved tag range.
The device has an on-chip rectification circuit that
converts the incoming rf signal to DC power feeding VDD.
APPLICATIONS
There is also an on-chip data modulator, which works in
conjunction with the rectifier. The time base is extracted

capacitor connected between the COIL1 and COIL2
pads. These features result in a single external
component count, comprised of, only the coil.
