Simplifying NVM integration during production

From initial data upload to content verification, the integration of a Non-Volatile Memory in a design can be time consuming, and results in costs for manufacturers.

With the Page EEPROM, ST provides a, NVM offering many features to reduce your manufacturing costs.

A NVM ready for data upload

The initial state in which the memory is delivered to manufacturers will determine a certain amount of the associated costs during production. The Page EEPROM is delivered ready to be programmed with an initial state erased at FF to save time and cost.

Fast programming for data upload

During the production phase, time is money. Every second spent programming the memory results in an additional cost for the manufacturer, especially when designs are created in mass-production. The Page EEPROM will help you reduce these costs thanks to a dedicated feature: the buffer load.

This feature hides the SPI communication and speeds up your programming time. Let’s compare a programming time with and without the buffer load:

    With 512 bytes per page and the buffer load feature, at 5MHz the Page EEPROM is 1.75x faster than a Serial Flash. If you have for instance 100 thousand products to program, you will spend:
  • ~ 66 hours with the Page EEPROM
  • ~ 110 hours with 4a Serial Flash

So, in this example, Page EEPROM lets you save you two production days.

Quickly program & reprogram your memory during production

You may need to reprogram your memory during your manufacturing process, which takes time and money. With ultra-fast erase performances, the Page EEPROM highly reduces the time spent for reprogramming your memory. It is almost 100x faster than a Serial Flash:

3.7 ms
for block erase
15 ms
for a chip erase

Monitor your design on the production line

On a production line, tracking and traceability data is a must to ensure that your application is manufactured correctly and on time. With the write byte operation, the Page EEPROM gives you the flexibility to monitor your product during the manufacturing phase.

Content verification

Once your memory is programmed, you may wish to check its content to be sure that the right data or firmware is implemented. With an 80 MHz quad output SPI interface, the Page EEPROM download speed reaches 320 Mbit/s, which enables a cost-efficient content verification on your production line.
