S12zvl EEPROM Erase sector time

[charudattaingal]

Dear Team,

I am using S12zvl 128 micro, It is taking 5.04ms to erase one sector (4 Bytes) on EEPROM

is there any way to reduce Erase sector time for EEPROM ?

Thanks & Regards,

Charudatta

Hi Charudatta,

Erase sector time for EEPROM cannot be significantly reduced. This time could be slightly influenced by NVM Operating frequency (0.8 .. 1.05MHz) and Bus frequency (1 .. 32MHz) while typical 5.04ms value is calculated for 1MHz fNVMOP and 32MHz fNVMBUS.

Additionally this time could grow during life time due to aging effect. Erase EEPROM sector time grows with number of EEPROM write cycles - that helps extend the endurance capability for the EEPROM.

I hope it helps you.

Have a great day,
RadekS
