| General description |
The EM4094 is an integrated analog system for 13.56MHz RFID reader system. It is highly versatile so it can be used in different reader systems having sub-carrier frequencies from 212KHz to 848KHz, hence covering ISO 14443 and ISO 15693 standards.
The adaptability is achieved using a 3 wires serial interface to program the system option bits. The transmitter generates 200mW output power into 50W load and is capable of OOK or ASK modulation.
