STMicroelectronics M95P32-I
M95P32-I - Ultra low-power 32 Mbit Serial SPI Page EEPROM
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 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.

X-NUCLEO-PGEEZ1 - Standard SPI page EEPROM memory expansion board based on M95P32 series for STM32 Nucleo
The X-NUCLEO-PGEEZ1 expansion board is designed for the M95P32 series SPI page EEPROM for data reading and writing.
This expansion board allows developers to evaluate the new memory page EEPROM through a single/dual/quad SPI interface.
It acts as an external storage device that can be used to store data, such as manufacturing traceability, calibration, user settings, error flags, data logs, and monitoring data to build more flexible and accurate applications.
The X-NUCLEO-PGEEZ1 expansion board can be plugged on top of an STM32 Nucleo-144 (via ZIO connectors) or STM32 Nucleo-64 (via Arduino® UNO R3 connectors).
