Ncycle

Write cycle endurance(2)

2. The Write cycle endurance is defined for groups of four data bytes located at addresses [4*N,

4*N+1, 4*N+2, 4*N+3] where N is an integer. The Write cycle endurance is defined by

characterization and qualification.

≤ 25 °C,

VCC(min) < VCC < VCC(max)

4,000,000

Write cycle(3)

3. A Write cycle is executed when either a Page Write, a Byte Write, a WRSR, a WRID or an LID

instruction is decoded. When using the Byte Write, the Page Write or the WRID instruction,

refer also to Section 6.6.1: Cycling with Error Correction Code (ECC).

Unit

Data retention(1)

1. For products identified by process letters KB. The data retention behavior is checked in

production. The 200-year limit is defined from characterization and qualification results.
