Power and Reset Considerations
Power-Up/Down Characteristics
In order to prevent any condition that may result in a spurious write or erase operation, it is
recommended to power-up F-V

Additional Flash Features
C3 SCSP products provide in-system programming and erase in the 1.65 V–3.3 V range. For fast
production programming, it also includes a low-cost, backward-compatible 12 V programming
feature.
Improved 12 Volt Production Programming
