DESCRIPTION This device is manufactured in the SAMES 1.2µm N-well EEPROM process. It has 64bits of factory pre-programmed and locked bits in EEPROM memory. Its mode of operation is factory pre-programmed and locked in additional EEPROM. The mode of operation is either manchester coded or Phase Shift Keyed (PSK) coded. The device has an on-chip rectification circuit that converts the ining rf signal to DC power feeding VDD. 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 is provided internally to protect against high voltages from the coil. The energy is stored on capacitance on chip due to low internal power consumption. These Features result in a low external ponent count. 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.
