Colorado Springs, C.O. EM Microelectronic announces the EM4569, a 125-kHz, 512-bit contactless identification CMOS RFID IC intended for use in electronic read/write RF transponders. The EM4569 offers several data rate and data encoding options available at a decreased level of power consumption. This passive RFID IC is optimized for high-performance, cost savings, and increased reading distance, making it well suited for animal identification.
The device is the enlarged pad version of the company's EM4469. The enlarged pads allow for direct antenna connection via bumps deposited on the enlarged pads, so it is possible to directly solder the wire of the antenna on the EM4569 without printed circuit board (PCB) support.
The IC has demonstrated performance in long range detection. "In a recent field trial using long-range animal readers, the EM4569 embedded in an ear-tag format was read at a distance of up to one meter, considerably more than other conventional RFID tags," explains Mougahed Darwish, president of the management board of EM Microelectronic. The device is compliant with ISO 11784/5 and has bi-phase RF/32.
Key features include:
- 512-bit EEPROM organized in 16 words of 32 bits
- 32-bit password read/write protection
- 32-bit unique identification number (UID)
- 10-bit customer code
- ISO 11784/ ISO 11785 standard compliant
- Lock feature converts EEPROM words in read only
- Multi-purpose encoding (Manchester, Biphase, Miller, PSK, FSK)
- Multi-purpose data rate from 1 up to 32k baud
- 00 to 150 kHz frequency range
- On-chip rectifier and voltage limiter
- No external supply buffer capacitor needed
- -40 to +85 degree C temperature range
The EM4569 is priced at $0.50 each in die form in 10,000-piece quantities. Click here for the EM4469 data sheet.
