تگ RFID R/W 125KHZ مدل جاکلیدی با امکان خواندن و نوشتن رنگ آبی

Introduction

T5577 Key | T5567 Key company American Atmel versatile non-contact R / W identification IC for 125 KHz frequency range.

Chips need to connect an antenna coil, which is regarded as the communication interface chip driver circuit power supply and two-way information. Antenna and chip together form a proximity card or tag.

T5557 Key | T5567 Key chip total of 330 bit EPROM (distribution of 10 blocks, each block 33 bit), the T5557 from the reader is read / write. Block 0 is a parameter configuration block is reserved for setting the operation mode of the T5557. Block 7 can be used for user data blocks, also thought to protect all the data blocks to set a user password to avoid unauthorized illegal rewritten. Data transmission is done from the load modulator IC identification. When receiving the IC reader scan field, will give birth to two terminals of the coil in the “1” and “2”, a sense of the RF field strength resistance, then 100% amplitude modulated for encoding and decoding, to obtain the reader related commands and data, and return the reader Key information.
