plot during an EEPROM page
erase.
2
This specification is not production tested, but is supported by characterization data at initial product release.

All internal amplifiers accept inputs with common range from GND to V
DD
2 V. The output is rail-to-rail, but the input is limited to GND to V
DD
2 V. See Figure 6.

These pins can be configured as open-drain N-channel or P-channel, (except PSON) and as normal or inverted logic polarity.
8
A logic true or false is defined strictly according to the signal name. Low and high refer to the pin or signal voltages.
9
Endurance is qualified to 100,000 cycles as per JEDEC Std. 22, Method A117, and measured at 40°C, +25°C, and +85°C. Typical endurance at +25°C is 250,000 cycles.
10
Retention lifetime equivalent at junction temperature (T
J
) = 55°C as per JEDEC Std. 22, Method A117. Retention lifetime based on an activation energy of 0.6 V.
Derates with junction temperature.
