This specification is a measure of I
DD
during an EEPROM page erase cycle. The current is a dynamic. Refer to Figure 29 for a typical I
DD
plot during an EEPROM page
erase.
2
Specification is not production tested, but is supported by characterization data at initial product release.

The maximum specification here is the maximum source current of Pin 8 as specified by the Absolute Maximum Ratings.
6
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.
7
These pins can be configured as open-drain N-channel or P-channel, (except PSON) and as normal or inverted logic polarity. Refer to Table 45.
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.
