Product Name :Rewritable and Read T5577 125KHz Flexible RFID Label Sticker

Rewritable and read T5577 125kHz flexible RFID label sticker is encapsulate with 125KHz rfid chipset and copper coil antenna .They can not use flip-chip technology like High frequency rfid sticker or UHF sticker because LF rfid sticker has meeted enough frequency and antenna turns .Normally we can see 125KHz rfid paper sticker surface can not pretty flat and hard to package with rolling .It rarely uses for some 125KHz RFID applications and curved surface adhesive on .

125KHz LF RFID sticker can with optional paper , flexible pvc or pet material as top , you can print colored artworks , numbers and UID ,etc . Considering better die-cut and laminated with paper top material ,the size should 30*30mm , 50*50mm and square or round shape are available . ATA5577 is kind of contactless read/write identification IC for applications in the 125kHz or 134kHz frequency band ,the on-chip 363 bits EEPROM (11 blocks with 33 bits each) can be read and written block-wise from a base station (reader ) ,it widely makes our flexible 125kHz rfid sticker can work many applications and data store inside chip .

Memory Map

ATA5577 Chip Memory Map

   Not transmitted

The memory is a 363-bit EEPROM, which is arranged in 11 blocks of 33 bits each. Each block  includes a single Lock bit, which is responsible for write-protecting the associated block. Pro-  gramming takes place on a block basis, so a complete block (including lock bit) can be  programmed with a single command. The memory is subdivided into two page areas. Page 0  contains 8 blocks and page 1 contains 4 blocks. All 33 bits of a block, including the lock bit, are  programmed simultaneously.

Advantage :

Factory RFID producing machines

Shenzhen ZhiJie IOT Application Co.,Ltd was exprienced rfid products manufacturers China since 2010 ,  we can help you to produce different kinds of frequency rfid products with 125KHz , 13.56MHz and 860-960MHz passive rfid chip . In our factory we have rfid card workshop ,  rfid label sticker workshop and some additional crafts card making department such as embossing , magnetic strip , encoding , hot-stamping , barcode ,QC and laboratory testing department .  Now we have more 12 sets flip-chip machines and winding antenna machines for meeting large quantities projects for you .

Our advantage as below :

1:ISO size and controlled tollerance in card producing .

2:Excellent printing in plastic rfid card , rfid label or paper rfid cards .  

3:Strictly in QC procedures and laboratory testing for keeping stablely feature of rfid products 

4: Stablely production time and quanlity gurantee for you 

5: RoHS certification and in-time response 

RFID laboratory testing machines

Applications :

125KHz RFID Sticker also widely uses for door contorl access ,identity management and some transportation tracking sticker .etc
