This specification is a measure of I
erase.
Specification is not production tested, but is supported by characterization data at initial product release.
Four external divider resistors are the same ration, which is selected to produce 2.0 V nominal at Pin 21 while at zero load current. Recommended values are
Chopper off.
The maximum specification here is the maximum source current of Pin 8 as specified by the Absolute Maximum Ratings.
All internal amplifiers accept inputs with common range from GND to V
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.
A logic true or false is defined strictly according to the signal name. Low and high refer to the pin or signal voltages.
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.
