EM4205V5DF2C+

RFID, RF Access, Monitoring ICS Overview

The EM4205V5DF2C+ is a CMOS integrated circuit designed for passive read/write RF transponders operating in the low-frequency range, typically around 125 kHz. It functions as a multi-purpose contactless identification device with 512 bits of user-accessible memory. The component supports ISO 11784 and ISO 11785 standards for livestock identification. It features an on-chip oscillator and requires no external components for basic operation, making it suitable for cost-effective RFID solutions.

RFID, RF Access, Monitoring ICS Procurement Notes

Verify the specific suffix 'V5DF2C+' against official datasheets to confirm package type and pin configuration. Ensure compatibility with existing reader hardware operating at 125 kHz. Confirm that the die or packaged form matches system integration requirements. Check for RoHS compliance status if environmental regulations apply. Validate supply chain authenticity through authorized distributors.

RFID, RF Access, Monitoring ICS Selection Notes

Select this component when designing passive LF RFID tags requiring 512-bit capacity. It is appropriate for applications needing standard ISO compliance for animal tracking. Consider its low power consumption and simple interface requirements. Evaluate space constraints if using the die version versus packaged options. Ensure the application environment falls within the specified temperature range.

RFID, RF Access, Monitoring ICS Part Context

This part belongs to the EM4205 family of RFID transponder ICs manufactured by EM Microelectronic. The family includes variants like EM4205V2WS6 and EM4305, differing in memory size and interface capabilities. The EM4205 series is widely used in global livestock identification programs due to its reliability and standard compliance.

RFID, RF Access, Monitoring ICS Replacement Considerations

Direct substitutes include other EM4205 variants such as EM4205V2WS6, provided the memory and interface requirements are met. Cross-reference with EM4305 if higher performance or different protocol support is needed. Verify pinout compatibility before swapping packages.
