General Description

TK4100/ TK28
is a CMOS integrated circuit for use in electronic Read Only RF transponders. It is compatible with EM format. The circuit is powered by external coil in an alternating magnetic field, and via one of coil terminal to get its clock from this field. The other coil terminal turns on and off the modulation current, the chip will send back the 64 bits of information contained in a factory pre-programmed memory array.

TK4100 chips data modulating and transmission is coded by Manchester modulation format. The programming of the chip is performed by laser fusing of polysilicon links in order to store a unique code on each chip. The continuous output data string contain 9 "1" headers, 40 bits, 14bits parity and 1 stop bit. No requirement of buffer capacitor for low power consumption of logic control core. Only an external coil is needed to obtain in the chip function. A parallel resonance capacitor of 74 pF is also integrated.

* Read only, Manchester, compatible with EM4200/ H4200
* On chip voltage limiter
* Full wave rectifier on chip
* Large modulation depth due to a low impedance modulation device
* Very small chip size convenient for implantation
* On chip 480PF resonance capacitor
* Operating frequency 100-150 kHz, typical frequency:125KHz
* Low power consumption
