A typical serial flash ensures a data endurance of 100K write cycles per sector and 20 years data retention. Table 9 details the maximum number of writes per day to the same sector that will allow the device to operate for a given number of years.
Desired Product Life in Years | Max Writes/Per Day |
---|---|
20 | 14 |
15 | 18 |
10 | 27 |
5 | 55 |
Max number of writes/day = 100000 / (product life in years * 365)
In a CC3100 and CC3200 system, the serial flash can be written by the user application or by the periodic activity of the CC3100/CC3200 on-chip firmware. The total number of writes from these two sources should not exceed the budget for maximum number of flash writes calculated from the desired product lifetime.
