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

Memory organisation
The structure of the 128 bits is as follows :
The header is sent first and is used to identify the start of the sequence. It is composed of 11 bits having a bit pattern which is
unique in the data stream. 00000000001
The header is followed by the Identification code which is composed of 64 bits organised in 8 blocks of 8 bits. Each block of
8 bits is trailed by a control bit set to logic "1" to prevent that the header is reproduced in the data. Bit 64 is transmitted first.
Bit 1 is a flag for animal "1" or non-animal "0" application.
Bits 2-15 are a reserved code for future use.
Bit 16 is a flag for additional data block "1" or no additional data block "0".
Bits 17-26 ISO 3166 Numeric country code
Bits 27-64 National identification code
The next two 8 bit blocks contain the 16 CRC-CCITT error detection bits. LSB is transmitted first, and the 2 block are trailed
with with a binary "1".
The data stream with 3 blocks of 8 bits trailed with a logical "1" representing the extension bits. The extension bits are
planned for future extension in which for instance information from sensors or contents of trailing pages may be stored. In the
current version the standard coding will be 000000001 000000001 000000001 and the flag bit 16 of the identification code
"0".
Resonance Capacitor
The Resonance Capacitor is integrated, and its value is typically 75 pF.
