TA = 145 °C(3), 2.5 V < VCC < 5.5 V - 400,000
1. 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, or for the status register byte (refer also to Section 5.3: Cycling with Error Correction Code (ECC)). The
Write cycle endurance is defined by characterization and qualification.
2. 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, refer also to Section 5.3: Cycling with Error Correction Code
(ECC).
3. For temperature range 4 only.
