Flash sector erase time

(4)

30k cycles 4000 ms

Flash write current Average delta current, 4 bytes at a time 6.2 mA

Flash write time 4 bytes at a time 21.6 µs

(1) A full bank erase is counted as a single erase cycle on each sector

(2) Up to 4 customer-designated sectors can be individually erased an additional 30k times beyond the baseline bank limitation of 30k

cycles

(3) Each wordline is 2048 bits (or 256 bytes) wide. This limitation corresponds to sequential memory writes of 4 (3.1) bytes minimum per

write over a whole wordline. If additional writes to the same wordline are required, a sector erase is required once the maximum

number of write operations per row is reached.

(4) This number is dependent on Flash aging and increases over time and erase cycles
