How can a Non-Volatile Memory reduce application downtime during firmware download & updates?



With electronic embedded systems becoming smarter, the lines of code required to run these applications are becoming increasingly complex. High-density NVM devices are used in systems to store the firmware package and its back-up.

The memory performance during firmware updates over the air (FOTA) plays a significant role in reducing application downtime.

Page EEPROM ensures fast device availability at all times

Start your application quickly

The application firmware is usually stored in a non-volatile memory. Thanks to its innovative architecture, the Page EEPROM achieves a 30µs wake up time and starts applications 10x faster than other serial NVMs.

Speed up firmware download

Once your application is powered-up, the microcontroller needs to download the firmware to its embedded memory to execute the software application. With an 80 MHz SPI Quad output interface, you will be able to download your firmware at 320 Mbit/s and enhance your application availability. The upgrade from standard EEPROM (limited to 10 MHz) to the Page EEPROM will significantly increase your download speed without raising your power budget. Read more about the Page EEPROM ultra-low power performance.

Page EEPROM is 32 times faster than standard EEPROMs to download 8Mbit of data

Update your firmware in an instant

  • The Page EEPROM takes x4 less than a standard 32 Mbit NVM to perform FOTA.
  • The 512 bytes program and erases operations with Page EEPROM are faster than a standard 32 Mbit NVM.

The firmware executed by an embedded system is often improved during application lifetime. To update this code, smart applications use firmware updates over the air (FOTA). With an ultra-fast block erase time of 4 ms and a 512 bytes page program in 1.2 ms, the Page EEPROM can reduce your downtime during FOTA updates.

Keep your code safe

When your application firmware is stored in an external NVM memory, it is important to guarantee its integrity, especially when you’re the initial version of the firmware should last for application lifetime. Page EEPROM comes with an Error Code Correction feature and provides 100 years data retention to keep your data safe. Find out more about data safety with Page EEPROM.
