Notes: 1. Measured with VPP = VPPH = 5V.
2. RP# should be held at VHH OR WP# held HIGH until boot block WRITE or ERASE is complete.
3. Polling status register before tWB is met may falsely indicate WRITE or ERASE completion.
4. WRITE/ERASE times are measured to valid status register data (SR7 = 1).
5. tREL is required to relock boot block after WRITE or ERASE to boot block.
6. Typical values measured at TA = +25ºC.
7. Assumes no system overhead.
8. Typical WRITE times use checkerboard data pattern.
