The figures are given after about 100 cycles due to testing routines (0 cycles at the final customer).

Word and Double Word Programming times are provided as average value derived from a full sector programming time:

Absolute value of a Word or Double Word Programming time could be longer than the provided average value.

Bank Erase is obtained through a multiple Sector Erase operation (setting bits related to all sectors of the bank).

Module Erase is obtained through a sequence of two Bank Erase operations (since each module is composed of two

banks).

Chip Erase is obtained through a sequence of two Module Erase operations on I- and X-Module.
