Description
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. The logic is mainly posed by a miller code generator and the LROM control. The memory is factory programmed so that each IC is unique.
