Table 24. Write AC Characteristics, Write 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).
