Microcontroller non volatile memories

STM8AF6268 microcontroller embedded into EPONA has two non-volatile memories:



Flash Program Memory (32k bytes): it is used to store the application code and

calibration parameters (if any).



EEPROM Data Memory (1k bytes): it can be used to store calibration data (if any) or

some other data that need to be preserved.

The main parameters that characterize EEPROMs is the retention time and the maximum

number of erase/write cycles: after the minimum guaranteed retention time and above the

maximum number of erase/write cycles, the data stored in the memory are no longer

guaranteed; for this reason, the program memory is trimmed to maximize the data retention

time at the expense of erase/write cycles' number whereas the data memory is trimmed to

maximize the erase/write cycles' number without compromising the retention time.
