EM Microelectronic, a semiconductor company in Marin, Switzerland, has introduced two new integrated circuits designed for low-frequency (125 kHz) RFID tags used in animal identification, waste management, industrial logistics and access control applications. The EM4205 and EM4305 chips comply with the ISO 11784 and 11785 RFID standards, developed for transponders that meet livestock tracking requirements. The ICs can be encoded to meet to the EN14803 waste management standard, EM Microelectronic reports, and they can also be used in tags for physical access control. The chips are manufactured using a process that protects them from UV damage, which can lead to memory loss. Additional user memory can be secured through a password. The chips also have fraud-prevention features, including a 32-bit unique identifier that enables traceability, e-pedigree and product authentication applications. The EM4305 chip is functionally equivalent to the EM4205 but comes with enlarged pads and gold bumps. These allow transponder manufacturers to directly connect the antenna wires to the chip, without the need of a PCB. This, the company explains, can help lower manufacturing costs and transponder size. Both chips are available now and are backward-compliant with the EM4569 chip.
