STMicroelectronics has introduced the launch of a brand new kind of reminiscence machine it is calling Web page EEPROM (Electrically Erasable Programmable Learn-Solely Reminiscence) — claiming to supply the ability effectivity of a conventional EEPROM with the capability and pace of a flash reminiscence module.
“The clever edge has advanced rapidly and is profoundly altering calls for on embedded reminiscence storage density, efficiency, and energy consumption,” claims STMicro’s Philippe Ganivet, supervisor of the corporate’s EEPROM product line, of the corporate’s new merchandise. “Our new Web page EEPROM is the proper ultra-low-power reminiscence to enhance a microcontroller for distant IoT [Internet of Things] modules that function on battery energy.”

The Web page EEPROM is, the corporate claims, the most effective of each phrases: it presents an influence effectivity in extra of most rival EEPROMs, together with a deep power-down mode of 1µA and a diminished write present of 1.5mA, but delivers efficiency 16 occasions increased — a claimed 320Mb/s learn pace. Longevity, in the meantime, is rated at a 100-year information retention and a 500,000-cycle write endurance — a number of occasions increased, the corporate factors out, than typical serial flash modules.
“ST’s Web page EEPROM is the proper non-volatile reminiscence, a real best-of-both worlds answer that enabled us to attain the formidable targets we set when creating the newest technology of our flagship product household of GPS trackers, IoT gadgets, and all different designs the place excessive efficiency, excessive reliability, small measurement, and low energy are required,” claims BitFlip Engineer’s Patrick Kusbel, an early recipient of Web page EEPROM samples. “The M95P is as much as 50 occasions quicker but consumes as little as one-tenth the ability and delivers 5 occasions the reliability — at 500k writes in comparison with 100k writes — typical of different components we used earlier than. It is a sport changer.”

The corporate has confirmed three fashions of Web page EEPROM for launch: the M95P08 8Mb (1MB), M95P16 16Mb (2MB), and M95P32 32Mb (4MB) variants. All help byte-level operations, web page, sector, and block eras, and web page programming of as much as 512 bytes, plus buffer-based loading for writing to a number of pages concurrently. The X-NUCLEO-PGEEZ1 analysis board hosts a single M95P32 Web page EEPROM, making it accessible over an SPI bus — and connecting an STM32 Nucleo-144 or STM32 Nucleo-64 as a protect for fast experimentation.
Extra data on the brand new components, which begin at $0.50 in tray portions, is offered on the STMicro web site; the corporate is promoting the X-NUCLEO-PGEEZ1 straight for $40.
