Word program (32-bit)(2)

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 0 erase (384K)(3)

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

Bank). As ST10F273 implements only one bank, the Bank Erase operation is equivalent to Module and

Chip Erase operations.
