General Description

The EM4094 is an analogue front end for 13.56MHz RFID reader systems.

It is highly versatile so it can be used in different reader systems having sub carrier frequencies from 212kHz to 848kHz, hence covering ISO14443 and ISO15693 standards.

The adaptability is achieved using a 3 wire serial interface to program the system option bits.
