Each column indicates that the corresponding supply is 0 and the other supplies are UP.
For example, the "Amps" cell in the "V
DD_HV_ADV_SD
=0" column shows that when
V
DD_HV_ADR_SD
supply is 0 and all other supplies are UP, this supply has a current in
Amp flowing into V
DD_HV_ADR_SD
.

1. Program times are actual hardware programming times and do not include software overhead. Block program times
assume quad-page programming.
2. Typical program and erase times represent the median performance and assume nominal supply values and operation at
25 °C. Typical program and erase times may be used for throughput calculations.
3. Conditions: ≤ 150 cycles, nominal voltage.
4. Plant Programing times provide guidance for timeout limits used in the factory.
