Description
The EM4006 (previously named H4006) is a CMOS integrated circuit intended for use in electronic Read Only transponders.
The exited coil connected to the device generates the power supply via a rectifier and an integrated decoupling capacitor. The clock used for the logic is also extracted from the coil. The logic is mainly composed by a miller code generator and the LROM control. The memory is factory programmed so that each IC is unique.
