EM Microelectronic has announced a family of RFID integrated circuits that operate at 13.56 MHz for contactless identification systems. The EM4035 contains a crypto algorithm for high security and can be used in a multiple access card. The EM4094 is a versatile reader IC compatible with all 13.56 MHz tags.

“EM Microelectronic’s 13.56MHz family is ISO15693-compliant.In parallel with 125 kHz RFID ICs, these circuits are used in applications that require crypto and secured access, such as security and access control, time and attendance tracking and asset management,” said Mougahed Darwish, president of the management board of EM Microelectronic. “The 13.56 MHz RFID ICs can typically read 20-40 tags per second. The new circuits are all compatible with the international standard ISO15693 defining protocols of RFID transponders in the 'vicinity range' of up to 1 meter.“

The EM4035 includes an ISO18000-3 mode 1=compliant crypto-algorithm with 96-bit secret key for symmetrical challenge/response, making it suitable for high-security hands-free access control, ticketing, anti-counterfeiting and asset management. The EM4035 is optimized for multi-applications such as access control and ticketing, making it possible to provide a secure, universal card. For example, the EM4035 could enable one card to be used simultaneously to access the library, swimming pool, ski facility and loyalty program. The EM4035 features a 3.2 Kbit EEPROM organized as 50 words of 64 bits, and each word can be irreversibly locked. The on-chip memory contains a 64-bit Unique Identifier (UID), with a six-bit chip type identifier and a unique 10-bit code that can be custom-programmed per customer request.

The EM4094 is a universal RFID reader IC that is compatible with virtually all 13.56 MHz RFID tags, including ISO15693 and ISO14443A&B, as well as proprietary protocols. Requiring minimal external components and a serial three-wire microcontroller interface, the EM4094 provides up to 200 mW of OOK or ASK modulation output from a single 5-V supply and is suitable for low-cost, handheld RFID readers and tag monitoring stations. The versatile EM4094 has AM/PM demodulation with AGC signal amplifier, multiple sub-carrier capability of 212 kHz, 424 kHz and 848 kHz and is compatible with Manchester or BPSK sub-carrier coding. The programmable device features built-in 400 kHz/1 MHz low-pass and 100/200/300 kHz high-pass filters, selectable receiver gain and power-down mode. Multiple receiver inputs are provided for redundant/diversity antenna arrangements to achieve enhanced communications reliability. The EM4094 operating temperature range is -40° to +85°C.
