6. Block diagram
The SL2 ICS53/SL2 ICS54 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.
