STMicroelectronics has claimed the industry’s first serial page EEPROM. Touted as a new class of EEPROM, this non-volatile device is a high-density, page-erasable SPI memory with ultra-low-power consumption. The first product launched is the M95P32 32-Mbit serial page EEPROM, which will be followed by 16-Mbit and 8-Mbit density options.
Available in two variants, the M95P32-I operates with a supply voltage from 1.6 to 3.6 V over an ambient temperature range of -40 °C to 85 °C (105 °C for the extended range) and the M95P32-E offers an extended range of temperature of -40°C to 105 °C. The devices support a clock frequency of up to 80 MHz. Both devices offer byte and page write instructions of up to 512 bytes.
Featuring ultra-low-power consumption, the devices consume only 0.6 μA (typ) in deep power-down mode, 16 μA (typ) in standby mode, 800 μA (typ) for read single at 10 MHz, and 2 mA (typ) for page write. Current peak control is <3 mA.
The serial page EEPROM family is based on an architecture that allows designers to mix firmware management and flexible data storage in the same device. This combination was not previously available, said STMicroelectronics.
The serial page EEPROM combines ST’s patented e-STM 40-nm non-volatile memory (NVM) cell technology with a new smart page architecture to deliver high memory density for firmware with byte flexibility. It also features fast read, erase, and program cycles, which enables rapid upload and download.
Providing a higher level of memory integration, the serial page EEPROMs also help reduce bill of materials, while enabling smaller modules with ultra-low-power operation, translating into longer battery life for a range of applications, said the company. They are suitable as all-in-one non-volatile memory in new system designs for applications such as industrial IoT modules, wearables, health care, medical, electronic shelf-edge labelling, smart meters, and 5G optical-fiber modules.
STMicroelectronics said the serial page EEPROM is a lower cost non-volatile memory solution than FRAM while offering lower power consumption as well as enhanced functionality and greater ease of use compared to serial Flash and Dataflash products, respectively.
