erase method FlexNVM

[pierluigirosset]

Hi team,

I 'd like to know some feature on the MK20DX256VLL10 about Flexmemory.

The device has 512KB total Flash, where 256KB are Flash and 256KB are FlexNVM,  and 64KB SRAM plus 4KB  EEPROM/FlexRam.

My question is:  I use part or full FlexNVM as Flash  and now  Can I to Erase single sector or I must entire block?

Which is  the minimun erasable memory space in FlexNVM as normal flash for  this device?

Ciao

Hello ,

In the reference manual of MK20DX256VLL10 chip , there is little about erase the flashNVM.

While i think you can refer to this manual "K20P64M72SF1RM.pdf" , this is about the MK20DX256VLH7, they are only the frequency is different.

On this RM, we can see :

this meaning in the flexNVM, the minimum erase size is 1 Kbyte.

Hope it helps

Alice
