Brief features:
64 bits memory organization written by laser programming;
There are some data transfer rates and decoding options;
Wide dynamic range on the chip buffer;
On-chip power/voltage limiter;
The chip has a full wave rectifier converter;
Use a low impedance modulation driver with large modulation depth;
Very small chip ruler for easy application;
A 480PF resonant capacitor is integrated inside the chip;
An energy storage buffer capacitor is integrated inside the chip;
Operating frequency range 100-150khz, typical value 125KHz;
Very low power consumption.
Operating conditions:
When the Manchester modulation code is used (typical mode, RF cycle to data bit cycle ratio is RF/64), as long as the AC induced voltage generated at both ends of the external coil of TK 4100 chip is ≥ 3.5VPp, and the coil clock frequency is about 125KHz, the chip is powered on and the operating temperature is -40 ~ +85℃.
Data format:
All data bits of TK4100 are 64 bits. It contains 9 start bits (each with a value of '1'), 40 data bits (8 vendor information bits
+32 data bits), 14 column parity bits (10 row parity bits +4 column parity bits), and 1 end stop bit.
When the TK4100 transmits information to a card reader or PC, it first transmits 9 start bits, then 8 chip manufacturer
information or version code, and then 32 data bits.
Typical applications:
Identification card;
Animal sensing response recognition;
Serial number identification for read-only storage;
Automated logistics management identification;
Industrial product response identification, etc.
A variety of application cards made by the TK 4100 chip are shown in the figure above.
Due to its small size, easy packaging and portability, and even embedded in products, the chip can be used in a wide range of applications.
For example: the identification of personnel, or the information management of goods, wine bottle cap built-in label, liquefied gas container security label, animal (such as carrier pigeon foot yellow identification label) identification, hotel access card, campus card, industrial and mining enterprise management card...
All can use a unique serial number to mark the main attributes of the object, can use it!
To be clear: The chip is fully integrated with a resonant capacitor of up to 480 PF, so the inductance of the external induction antenna can be greatly reduced and the number of turns of the antenna coil can be doubled, which means that in the 125 KHz read-only ID card series, TK4100 chip can be used to make a very light, small and thin label card or a light and easy to carry keycard.
