From 8 to 32-Mbit

Next-gen memory: blending EEPROM with Serial Flash


Serial Flash & EEPROM: What if a bridge existed?

Serial Flash & EEPROM: What if a bridge existed?

Serial Flash memories are high-density (1 Mbit-2 Gbit) with high-speed operation, which simplifies firmware management. EEPROMs are ultralow power memories with high cycling endurance and retention. Robust and reliable, EEPROMs are ideal for monitoring data and storing sensitive parameters.


Selecting between a Serial Flash and an EEPROM once involved complex trade-offs. ST's Page EEPROM innovation is changing that. 

Page EEPROM: the ideal choice for battery-operated devices

With its ultralow power consumption, the Page EEPROM is an ideal choice for battery-operated applications such as IoT trackers, wearables, monitoring and medical devices, or tiny camera modules. The Page EEPROM comes in three densities: 32, 16 & 8 Mbits.


Combining the advantages of Serial Flash and EEPROM memories, the Page EEPROM provides the flexibility to manage application firmware similarly to a Serial Flash while offering intensive data logging capabilities like an EEPROM.
