Data is read at the RF interface by means of the on-chip  
modulator. The stored bits are clocked out sequentially  
during the read operation. An internal power-on reset is  
provided which allows the device to start reading out data at  
low voltages for improved tag range.  
DESCRIPTION  
This device is manufactured in the SAMES 1.2µm N-well  
EEPROM process. It has 128 bits, factory pre-programmed  
and locked in EEPROM memory. Read data is Manchester  
coded.  
APPLICATIONS  
The device has an on-chip rectification circuit that converts  
the incoming rf signal to DC power feeding V . There is

also an on-chip data modulator, which works in conjunction  
with the rectifier. The time base is extracted by an on-chip  
RF clock extractor. High voltage protection across the coil  
inputs is provided internally. The energy is stored on  
capacitance on chip due to low internal power consumption.  
The device has an on-chip resonance capacitor connected  
between the COIL1 and COIL2 pads. These features result  
in a single external component count, comprised of, only the  
coil.
