STMicroelectronics has introduced a new generation of memory chips that combine storage density with speed and reliability, enabling the devices we use every day to do more to enrich life and work. 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 recognised 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 data storage with energy efficiency for budget-conscious applications. They extend ST’s wide portfolio recognised 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 1,000 pieces.

M95M04 EEPROMs provide high-density non-volatile storage for persistent data such as application code, calibration tables, and user parameters, as well as for intensive data logging.

Offering the highest density on the market in small eight-pin SO8N and TSSOP8 packages, they are cost-effective versus competing devices. These include EEPROM-emulation memories that combine a microcontroller and Flash, ferroelectric FRAMs, and magneto-resistive MRAMs, which consume more power and have narrower supply-voltage range than CMOS EEPROMs.

M95M04 EEPROMs benefit from a wide power supply range of 1.8 to 5.5V, as well as 40-years data retention, and an eight-bump WLCSP chip-scale package option in addition to SO8N and TSSOP8 packages.
