Program/erase count - MC9S12XET256.

[subashr]

I'm working on DFLASH for MC9S12XET256.

Query is related to Program/erase cycles. 

The sector is in erased state now.

In that sector, if I write 10 bytes at different time intervals for 5 times (different address in the sector), will it be counted as a 1 or 5 Program/erase cycles.

My understanding is that this will be counted as 1 Program/erase cycles as only one erase is done for that sector.

Hi Subash,

Yes, your understanding is correct.

The cumulative writes are not allowed. Therefore 1 program cycle refers to 1 erase cycle for each bit.

So, we may say that Program/erase cycle term rather equals to erase cycle.

BTW: This principle is used for emulating EEPROM – EEPROM content change will invoke just a new record programming instead complete erase/program cycle…

I hope it helps you.

Have a great day,
Radek
