STMicroelectronics NV has developed a M24LR16E 16-kbit memory that can also harvest enough energy to enable small electronic items using it to become battery-free electronic applications. STMicroelectronics is the Europe’s largest chip company.

ST has showed the possibilities of designing with the M24LR16E energy-harvesting wireless memory by illuminating indicator LEDs as well as by powering its battery-less STM8L-based low-power microcontroller development kit. Other potential applications include e-paper devices such as electronic shelf labels, as well as industrial automation, sensing and monitoring systems, and personal healthcare product.

The M24LR16E EEPROM is part of ST’s RFID/NFC range of memories. The M24LR16E requires a 1.8 to 5.5-V supply. It is a dual-interface memory that offers 40 years of data retention, 1 million write/erase cycles and an RF interface operating at 13-56-MHz compatible with RFID reader-writers and ISO15693-capable NFC devices.

The RF interface is also able to harvest ambient radio wave energy emitted by RFID reader-writers, and it converts those waves into a voltage output that may be used to power other electronic components. The M24LR16E is packaged with SO8, TSSOP8 or MLP8, and it is available in volume production.
