#172481 - EEPROM Protection |
Hi All
I'm working with SPI EEPROM (32 KB). I want to use software protection mode (using BP0 and BP1 in status register). In my application I write EEPROM every 10S, and using Circular buffer technique. I want to protect the EEPROM and only open the protection when writing to it. I read the data sheet that BP0 and BP1 is non-volatile. In my applucation I should write/change BP0 and BP1 every 10S. Question: 1. Is there any write cycle (endurance) for BP0 and BP1? Or Is it same with memory endurance of EEPROM itself? 2. Anybody know why in software protection mode we only can select whole memory or upper area of memory? Why we can not select lower memory (ex. 0000 - 4000H)? Thanks |
