Block diagram

The SL3 ICS 10 IC consists of three major blocks:

Analog RF Interface

Digital Controller

EEPROM

The analog part provides stable supply voltage and demodulates data received from the

reader for being processed by the digital part. Further, the modulation transistor of the

analog part transmits data back to the reader.

The digital section includes the state machines, processes the protocol and handles

communication with the EEPROM, which contains the EPC and the user data.
