Notes 1. Depending on the erasure count (NERASE), the erase time varies. Refer to the chip erase time and block
erase time parameters.
2. When the average temperature when operating and not operating is 85°C.
Remark When a product is first written after shipment, âerase â writeâ and âwrite onlyâ are both taken as one rewrite.
