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 values derived from a full sector programming time:

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

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

ST10F271 implements only one bank, the Bank Erase operation is equivalent to Module and Chip Erase operations.

Not 100% tested, guaranteed by Design Characterization.
