Description
The H4005 is a CMOS integrated circuit intented for use in
electronic Read Only RF Transponders. The circuit is
powered by an external coil placed in an electromagnetic
field, and gets its master clock from the same field via one of
the coil terminals. The other coil terminal is affected by the
modulator. By turning on and off the modulation current, the
chip will send back the 128 bits of information contained in a
factory pre-programmed memory array.
The programming of the chip is performed by laser fusing of
polysilicon links in order to store a unique code on each chip.
Due to the low power consumption of the logic core, no
supply buffer capacitor is required. Only an external coil is
needed to obtain the chip function. A parallel resonance
capacitor of 75 pF is also integrated.
Applications
Animal implantable transponder
Animal ear tag
Industrial transponder
