Integrated Circuit for Electronic Identifiers.




Basic specifications.
integrated circuit of asynchronous code generator.
Technology - CMOS on silicon,
Size of crystal 1.2x1.5 mm,
Number of contacts pin 2 (250x250mm),
Supply voltage, VDD - 1.5-30V DC
Code mechanism time-impulse code - CHIPCODE,
Length of single impulse 1 ms.
Length of code word 64 bits.
Duration of code sequence - 4ms (at 3V VDD),

CHIPKEY- generates continuous sequence of short impulses with CMOS standard amplitude as shown above. Sequence of time intervals Ti, between the nearest impulses arranges informational code CHIPCODE that has been patented. Schem
CHIPCODE is different in structure from traditionally used for chipcards - Manchester-code and similar codes.
CHIPCODE is asynchronous time-impulse type of codes, which is more preferable to be used for one channel communication line, like: - RF-channel, optical fiber or acoustic lines and main power lines.
CHIPCODE recognize the break of bit sequence just after the bad bit occurs, while Manchester-like code require to analyze whole code word construction to detect false transaction.
CHIPCODE allows transferring of every bit of information with arbitrary interval between every bit like in Morse code.
CHIPCODE, in spite of asynchronous transfer (with possible floating of voltage supply, or interference with time disturbances), could be reliably decoded due to autosyncronization on the level of bit construction, and autosyncronization on the level of word construction.
CHIPCODE improves reliability of large distance code receiving due to the rather high amplitude of short impulses while average transmitter power consumption remains low.
CHIPCODE provide highly economic power consumption in transmission process.
CHIPKEY can be used as a coder device for large variety of electronic circuits and all entire features described above advance read out technologies for proximity and remote CHIPKEY identifiers and are successfully utilized in our piezopowered electronic circuits for Batteryless Electronic Systems like CHIPLOCK devices or Batteryless Remote Control

Various identifiers have been developed on the base of CHIPKEY in the form of contactless and proximity modules for plastic cards, tags.
Topology of microchip CHIPKEY has been registered at Russian Patent Agency.
CHIPKEY microchips are coded at the step of last photolithography on the wafer and due to the very large amount of combinations all of the chips bear unique codes.
All readers for CHIPKEY have link with PC and can be supplied with net protocol for local net version.
We can produce & supply more then 1 million CHIPKEY chips per month.
Licenses for CHIPKEY production at any other silicon plant in USA, EUROPE, or ASIA are also provided.
CHIPKEY and corresponding transponder technology has been awarded by Golden Medals of International Invention Show " BRUSSELS-EUREKA'96,'97."

Main applications of CHIPKEY RF ID.

At the mean time in accordance with the evolution of the electronics, logistic and information technologies, development of global link communications there are high rates of growth of consumer market are observed for the systems of electronic access control, systems of automatic stock-taking, systems of distance recognition and identifying of objects.

Electronic identifiers are the elements of that market:
            -Personal plastic cards,

            -Coded tags,
            -Coded laser pointers,
The most developed systems with RF ID are:
            -Access control,
            -Corporate local PC-nets access and systems for time attendance calculation,
            -Systems of hotel service with electronic locks and credit accounting for guests,
            -Electronic identity cards, students identifiers, insurance cards,
            -Multiple electronic tickets and baggage tags,
            -Global systems of discount cards,
            -Automaton for parking and many floor garages,
            -Systems for RF-passive tracking and access control at military objects, wholesale stocks, etc,
            -Global emergency systems with personal radiobeacons at rescue facilities,
            -Systems of active identifications at mass events like
            -Olympic games, gala-concerts, etc.,
            -Electronic code tags for customs, cash bags, cargo containers,
            -Electronic implantable tags for breeding industry of animals and birds, 

A lot of applications may be arranged with the help of electronic tags:
            -Container tags,
            -Pallet tags,
            -Package tags,
            -License and excise tags,

            -Vehicle tags,
            -Baggage tags,

            -Laundry and clothes tags,
            -Stock and inventory tags,
            -Tags for home and industrial animals,
            -Customs lead,
            -Various electronic tokens for:
                        -waiting rooms,
                        -vending machines,
                        -cloak room,
            -Electronic lottery tags or cards.
