Data Sheet
For T
One cycle refers to the programming of all wordlines in a sector and erasing of sector. The Flash endurance
data specified in
- the maximum number of erase cycles per Flash sector must not exceed 100,000 cycles.
- the maximum number of erase cycles per Flash bank must not exceed 300,000 cycles.
- the maximum number of program cycles per Flash bank must not exceed 2,500,000 cycles.
If no Flash is used for data, the Program Flash size can be up to the maximum Flash size available in the
device variant. Having more Data Flash will mean less Flash is available for Program Flash.
A
=125 to 140°C, refers to programming of second 8 bytes (bytes 8 to 15) per WL
