STMicroelectronics reveals Web page EEPROM two-in-one reminiscence to spice up smart-edge efficiency and effectivity

New best-of-both reminiscence combines serial Flash pace and density with EEPROM byte-level flexibility

STMicroelectronics’ Web page EEPROM combines the ability effectivity and sturdiness of an EEPROM with the capability and pace of a Flash reminiscence, making a hybrid reminiscence for purposes that face excessive measurement and energy constraints.

The brand new reminiscences handle rising demand for storage in embedded purposes, wanted to assist more and more subtle options and run data-hungry edge-AI algorithms. One instance is behind-the-ear listening to aids, the place Web page EEPROM can scale back the invoice of supplies and assist create merchandise which can be slimmer and extra comfy to put on.

Along with wearables, Web page EEPROM is right for purposes comparable to healthcare gadgets, asset trackers, e-bikes, in addition to different industrial and client merchandise. “The clever edge has advanced shortly and is profoundly altering calls for on embedded reminiscence storage density, efficiency, and energy consumption,” mentioned Philippe Ganivet, STMicroelectronics EEPROM product line supervisor.  “Our new Web page EEPROM is the proper ultra-low-power reminiscence to enrich a microcontroller for distant IoT modules that function on battery energy.”

“ST’s Web page EEPROM is the proper non-volatile reminiscence, a real best-of-both worlds resolution that enabled us to realize the bold 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,” mentioned Patrick Kusbel, proprietor of BitFlip Engineering, one of many first clients to make use of the brand new reminiscence ICs. “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’s a recreation changer.”

ST’s Web page EEPROM household gives densities of 8Mbit, 16Mbit, and 32Mbit, drastically rising storage over commonplace EEPROM gadgets. Embedded good page-management permits byte-level write operations for processes like knowledge logging, whereas additionally supporting web page/sector/block erase and page-program as much as 512 bytes for effectively dealing with firmware over the air (OTA) updates. The gadgets additionally enable buffer loading, which may program a number of pages concurrently to chop the time for loading software program in manufacturing. The information-read pace of 320 Mbit/s is about 16 occasions quicker than commonplace EEPROM, whereas write-cycle endurance of 500,000 cycles is a number of occasions increased than typical serial Flash.

Additionally that includes a novel peak-current management, Web page EEPROM minimizes energy provide noise and prolongs the runtime of battery-operated tools. The write present is under that of many typical EEPROMs and there may be additionally a deep power-down mode with quick wakeup that reduces the present to under 1µA.

Longevity is assured, with 100-year knowledge retention. The gadgets are included in ST’s 10-years product longevity program that ensures long-term product availability.

The X-NUCLEO-PGEEZ1 growth board and X-CUBE-EEPRMA1 software program bundle can be found now, for customers to learn to work together with Web page EEPROM and undertake the brand new gadgets in software designs. The software program features a demonstration software that reveals methods to take a look at the reminiscence’s hybrid structure and shortly construct a proof of idea.
