EM Microelectronic H4006
The 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 Graetz bridge and an integrated decoupling capacitor. The clock used for the logic is also extracted from the coil.FEATURES
