STMicroelectronics — M95P32 SPI Page EEPROM

STMicroelectronics M95P32 SPI Page EEPROM

Ultra low power 32-Mbit serial SPI page EEPROM with dual and quad outputs

STMicroelectronics’ 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 ultra-low power consumption, equivalent to that of EEPROM technology.

The M95P32-I and M95P32-E are a 32-Mbit SPI page EEPROM device organized as 8192 programmable pages of 512 bytes each, accessed through an SPI bus with high-performance dual- and quad-SPI outputs.

The device offers two additional (identification) pages of 512 bytes:

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

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). 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 of self-timed auto erase and program operations, resulting in flexible data byte management.

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

The memory can then be fast-programmed by pages of 512 bytes, and further optimized using the "page program with buffer load" to hide the SPI communication latency.

8 to 32Mbit Page EEPROM

Based on advanced 40nm process technology and a new architecture, Page EEPROM goes beyond today's market-standard EEPROMs. Available in SO8N, DFN8 and WLCSP8 packages, the Page EEPROM product family brings the benefits of Serial EEPROM with breakthrough performance.
