Thin 125KHz RFID Card with EM4305 Chip for Access Control

Thin low-frequency 125KHz RFID card with EM4305 chip for access control is a white PVC RFID card, size 85.6*54mm, thickness 0.84mm, frequency 125Khz, EM4305 chip, glossy white surface printable with a thermal printer.

Key Features

• Material: PVC
• Size: 85.6*54mm
• Thickness: 0.84mm
• Frequency: 125Khz
• Chip: EM4305
• Glossy white surface printable with a thermal printer
• EM4305 is a CMOS integrated circuit for electronic read/write RF transceivers
• EM4305 is bumped with extended pads for two coil inputs, allowing direct antenna connection, avoiding the need for a module
• EM4305 has a 330pF resonant capacitor version
• The IC is powered by harvesting energy from a continuous 125 kHz magnetic field through an external coil, combined with an integrated capacitor to form a resonant circuit
• The IC reads data from internal EEPROM and transmits it by switching a resistive load in parallel with the coil using a large modulation index
• Commands and EEPROM data updates can be executed using 100% AM modulation of the 125 kHz magnetic field
• EM4305 supports bi-phase and Manchester data encoding
• The EM4305's operating modes are stored in an EEPROM configuration word
• All EEPROM words can be write-protected by setting protection bits
• The IC contains a unique 32-bit identification number (UID) programmed at the factory

Suitable Applications

• Access control
• Time attendance
• Animal identification per ISO FDX-B
• Pigeon racing standard
• Waste management (BDE)
• Industrial
