General Description

The H4001 is a CMOS integrated circuit for use in transponders.

The circuit is powered by an external coil placed in a magnetic field, and gets its clock from the same field via one of the coil terminals.

The other coil terminal is affected by the modulator, turning on and off the modulation current in order to send back the 64 bits of information contained in a factory pre-programmed memory array.
