How can a Non-Volatile Memory make datalogging more efficient and accurate?

Simplified event recording and read/write instructions

• Page EEPROM simplifies the write instruction, as it automatically erases data before programming the new values.
• The write instruction is very flexible as it can handle a single byte and a full page of content, depending on applications needs.

• Page EEPROM speeds up the program instruction, as it bypasses the erase step and stores 512 bytes in 1ms
• The Page EEPROM buffer mode optimizes the storage time of big data blocks. The page program (PGPR) with buffer load instruction allows from one to 512 bytes of data, initially in the erased state (FFh), to be programmed. It also allows the buffer of 512 data bytes for the next page program operation to be loaded during page program execution. For more information on the buffer mode, download the technical note
• Event sectors and blocks can be cleared at any time thanks to very fast erase instructions that last for less than 5ms

Enabling intensive datalogging for more accuracy

The datalogging frequency
• SPI communication up to 80MHz that minimizes the communication time
• A high cycling endurance of 500k per page, which simplifies datalogging and eliminates the need for a complex wear levelling strategy.
• The NVM’s cycling performance, which enables 120 updates by day over 10 years on the same page without requiring any specific strategy.

High data reliability with embedded ECC

The Page EEPROM safeguards data integrity thanks to the embedded Error Code Correction feature. The ECC protects against singleand double-bit fails, as it can correct singleor double-bit errors and detect triple-bit errors. The data locations are submitted to high stress and can therefore become weak after a certain amount of time. The embedded ECC feature guarantees data retention for 10 years after cycling stress and is transparent for the user. Read more about the ECC feature.

The serial Page EEPROM combines a set of features, which make datalogging and event recording functions efficient and robust. Fast 80MHz SPI interface combined with flexible fast write and program instructions reduce data storage operations and execution times. The high cycling performance of 500K cycles per page simplifies datalogging, while the embedded ECC ensures data robustness during application lifetime.
