16-kbit memory for Energy harvesting

Published:2012/3/12 3:51:00 Author:Ecco From:SeekIC

STMicroelectronics NV has pushed a 16-kbit memory that can also harvest enough energy. The M24LR16E EEPROM is part of ST’s RFID/NFC range of memories. The memory makes the small electronic items become battery-free electronic applications. STMicroelectronics NV is the Europe’s largest chip company.

The M24LR16E 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 M24LR16E needs 1.8 to 5.5-V supply.

The RF interface is also able to harvest ambient radio wave energy emitted by RFID reader-writers. Then it converts those waves into a voltage output that may be used to support other electronic components. A Vout analog pin is provided for this purpose but ST did not provide quantitative details of the output capabilities of the energy harvest system..

ST’s M24LR16E energy-harvesting wireless memory’s 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 is available in SO8, TSSOP8 or MLP8 surface-mount packages. And RFID is now used in supply-chain and retail businesses, and NFC technology will be included in more than 500 million mobile phones sold annually by 2015, citing ABI Research as its source.
