Is it possible to carry out delete/write in the on-chip flash memory?

Latest Updated:03/21/2012


Is it possible to carry out more deletes/writes in the on-chip flash memory than specified in the Section "Flash Memory Characteristics", Chapter "Electrical Characteristics" of the User's Manual: Hardware?


The number of times for write/delete specified in the User's Manual: Hardware is on the assumption of guaranteeing all the characteristics including data hold period (10 years) after rewriting. Writing data for the number of times exceeding that specified in the User's Manual is enabled. When the long-term data preservation and guarantee is not necessary such as the time of debugging assessment, write processing can be repeated until rewrite is disabled.
