With 4Mbit capacity, ST’s new EEPROM memories let small devices capture and store more data through the serial SPI bus. This enables equipment such as smart meters to intensify data logging for managing grids more effectively and providing more user-friendly billing.

Also, portable medical devices can log patients’ data more intensively to improve care quality, and consumer devices such as smart wearables can support more user features and greater precision. In these applications, the memory’s low power consumption helps extend battery runtime. A wide range of applications in industrial controls and communication infrastructure such as network switches can also benefit from these higher density memories.

“ST is recognized as the world leader in serial EEPROM chips, which are widely used across consumer, industrial, and automotive applications, and we continue to drive technical innovation,” said Benoit Rodrigues, Memory Division General Manager, STMicroelectronics. “The market’s first 4Mbit EEPROM devices are produced in our own CMOS technology, which is now qualified at 110nm as the most advanced in the industry for EEPROMs.”

ST’s M95M04 EEPROM memories combine their unprecedented data storage with excellent energy efficiency for budget-conscious applications. They extend ST’s wide portfolio recognized for high reliability, lasting one billion full-memory read-write cycles. Capable of writing 512 Bytes in 5ms, the new devices enable fast system operation with low latency.

Samples are available now, and pricing starts at $2.50 for orders of 1000 pieces.
