Chip description:

TK4100 is a read-only CMOS integrated circuit micro ID chip widely used in 125KHz RF proximity cards. The chip is compatible with EM format. The TK4100 chip circuit is powered by an external antenna coil on an alternating magnetic field and derives its clock frequency from the magnetic field via one of the coil terminals. The other coil terminal is affected by the internal modulator of the chip and is converted to current-mode switching modulation to transmit 64-bit information and commands containing the manufacturer's pre-program arrangement to the card reader.

The data modulation and transmission of the TK4100 chip is encoded in the commonly used Manchester (Manchester) modulation format. The chip is laser programmed during the polysilicon bonded state to store a unique code on each chip. The continuous output data string contains 9 '1' headers, 40 bits of data, 14 bits of parity, and 1 bit of stop bits. Due to the low micro-power consumption of the logic control center, there is no need to provide a snubber capacitor. Only the energy of the chip operation needs to be obtained by an external antenna coil, and a capacitor integrated in parallel with the external coil can obtain resonance energy absorption.

Brief features:

• 64bits memory organization programmed by laser programming;
• has a wide dynamic range on the chip buffer;
• The battery has a power/voltage limiter;
• Full-wave rectifier converter on the chip;
• Use a low impedance modulation driver with a large modulation depth;
• Very small chip scale for easy porting applications;
• 480PP resonant capacitor is integrated inside the chip;
• The internal storage of the chip has an energy storage buffer capacitor;
• Operating frequency range is 100-150KHz, typical value is 125KHz;
• Very low power consumption.
