Table 25. Write AC Characteristics, Chip Enable Controlled (1)
(TA =0 to 70°C or –40 to 85°C)
Note: 1. See AC Testing Measurement conditions for timi ng measurements.
2. Sampled only, not 100% tested.
3. The device Reset is possible but not guaranteed if tPLPH < 100ns.
4. The reset will complete within 100ns if RP is asserted while not in Program nor in Erase mode.
5. Applicable if VPP is seen as a logic input (VPP < 3.6V).
