DC CHARACTERISTICS - CMOS COMPATIBLE
(VCC = 5.0V, GND = 0V, TA = -55
°C to +125°C)
NOTES:
1. The Icc current listed is typically less than 2mA/MHz, with OE at VIH.
2. Maximum Icc specifications are tested with VCC = VCC max.
3. ICC active while Embedded Erase or Embedded Program is in progress.
4. Not 100% tested.
5. ICC3 = 20
A max at extended temperature (> +85°C).
