RFID LF Chip (125KHz)

RFID LF tecnology 125KHz is the first RFID technology to be used. Nowadays it is a established reality, so the requirement of tags with LF chip 125KHz is still high. However new applications seek to exclude LF 125KHz from the proposals because there isn’t an universally accepted standard and the communication speed  is  quite slow. So, we underline the main LF chips:

EM4100 / TK4100: 64Bit Read Only chip (without User Memory). It is the most used and cheapest chip. Controllers encode UID in different waysaccording to application needs (with decimal code, with hexadecimal code, with 13-digit code, etc.)

T5577: Chip Read/Write with 224bit User Memory.

HitagS: Chip with two different memory options 256Bit and 2048bit. For further information: Datasheet HitagS
