STMicroelectronics M95P08-IXCST/EF

The M95P08-I and M95P08-E are manufactured with ST's advanced proprietary NVM technology. They offer byte flexibility, page alterability, high page cycling performance, and ultra‑low power consumption, equivalent to that of EEPROM technology.

The M95P08-I and M95P08-E are an 8-Mbit SPI page EEPROM device organized as 2048 programmable pages of 512 bytes each, accessed through an SPI bus with high-performance dual- and quad SPI outputs.

The devices offer two additional (identification) 512-byte pages:

Additional status, configuration, and volatile registers set the desired device configuration, while the safety register provides information on the device status.

The M95P08-I operates with a supply voltage from 1.6 to 3.6 V over an ambient temperature range of -40 °C to +85 °C.

The M95P08-E offers an extended temperature range from -40 °C to +105 °C. The device supports a clock frequency of up to 80 MHz.

The M95P08-I and M95P08-E offer byte and page write instructions of up to 512 bytes. Write instructions consist in self-timed auto erase and program operations, resulting in flexible data byte management.

The devices also accept page/block/sector/chip erase commands to set the memory to an erased state.

The memory can then be fast-programmed by 512-byte pages, and further optimized using the Page program with buffer load instruction to hide the SPI communication latency.
