The M95P32-I and M95P32-E are manufactured with ST's advanced proprietary NVM technology. They offer byte flexibility, page alterability, high page cycling performance, and ultralow power consumption, equivalent to that of EEPROM technology.
The devices are a 32-Mbit SPI page EEPROM, organized as 8192 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 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. The M95P32-E offers an extended range of temperature of -40 °C to +105 °C. The device supports a clock frequency of up to 80 MHz.
The M95P32-I and M95P32-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, and 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.
