STMicroelectronics — M95P Serial EEPROM Memory Products

STMicroelectronics created the industry’s first family of serial page EEPROM memory. This family is an extension of the ST EEPROM portfolio, and is available in three density options: 

• 8 Mbit M95P08  

• 16 Mbit M95P16 

• 32 Mbit M95P32 

These high-density EEPROM are page-erasable SPI page memory devices that combine flexibility and high performance with ultra low-power consumption. The bytes are tied together in 512-byte pages, and can be written even if they are not erased. These bytes can be accessed through an 80 MHz SPI bus, with high-performance single-, dual- and quad-SPI outputs. 

The innovative page EEPROM architecture gives designers the flexibility to perform firmware management and data logging with the same device, a combination that usually calls for a serial NOR Flash and an EEPROM. This integrated solution reduces bill-of-materials cost and shortens time-to-market. It also enables designers to realize designs for smaller modules with ultra low-power operation, giving longer battery run-time in wearable and portable products.  

An innovation in embedded memory, serial page EEPROM combines the ST advanced proprietary non-volatile memory technology with a new smart page architecture, bringing together the benefits of high memory density for firmware management and easy data logging with byte flexibility and high endurance. The technology also features fast read, erase, and program times, reducing manufacturing costs and application downtime by enabling rapid uploads and downloads. Fast power-up and a quad-output read capability allow for faster application wake-up. 

Serial page EEPROM offers a non-volatile memory solution that is less expensive than ferroelectric RAM. It also offers lower power consumption as well as more functionality and greater ease of use than serial Flash and dataflash.
