Notes for DC characteristics (both tables):
1. The ICC current listed includes both the DC operation current and the frequency dependent component (at 6 MHz).
The frequency component typically is less than 2 mA/MHz, with OE at VIH.
2. Maximum ICC specifications are tested with VCC = VCC max.
3. ICC active while Embedded Algorithm (program or erase) is in progress.
4. Not 100% tested.
5. For CMOS mode only, ICC3 = 20
µA max at extended temperatures (> +85°C).
6.
RESET is not available on A290021.
