M95P32

Ultra-low power EEPROM combines datalogging and firmware management on a single memory

M95P32 is a high-density, page-erasable SPI EEPROM memory that combines unprecedented flexibility and performance. This all-in-one non-volatile memory has been designed for ultra-low power applications requiring robust and flexible datalogging as well as fast firmware upload/download.

Easy to implement, ST’s ultra-low power 32Mbit Page EEPROM offers 16 Mbit and 8 Mbit density options. Its unique architecture enables fast boot times and helps save energy in every operation, thanks to controlled current peaks and a reduction of the power dissipation.

Developers can now build new designs for their power-constrained applications, such as compact IoT modules powered by small batteries. They can also reduce the cost of their BOM, using one single memory, instead of two (Serial Flash and EEPROM).
