The M24LR64 is an EEPROM memory with a standard I²C serial interface, providing communication with most microcontrollers or ASICs, and also a standard ISO15693 RF (radio frequency) interface for wireless communications with RFID readers. No power is required to operate the M24LR64 in RF mode, which enables on-board energy savings and provides easy and convenient remote access to electronic product parameters.

Based on two industry-standard interfaces, the new dual-interface product line provides a link between the operation of electronic devices and the RFID world. This will enable new types of products, including those requiring asset tracking, data collection, diagnostics, or traceability, such as medical devices, industrial equipment, and automotive electronics, according to ST.

The M24LR64 has a 64-Kbit capacity for storage of program code, product parameters, serial numbers, calibration data, or event-log data. Its RF ISO15693 interface can be accessed by a wide range of RF readers, covering hand-held devices, pad antennas, gate systems and tunnel readers. The memory also communicates with the host system via an industry-standard I²C interface operating at 400kHz from 1.8 to 5.5V.

Pricing: From $0.90 for orders of 1000 pieces.
Availability: Sampling has already begun, with volume production scheduled for Q2 2010. ST plans to introduce additional members in the second half of 2010.
