NOTES:

1.The ICC current listed includes both the DC operating current and the frequency dependent component (@ 5 MHz). The frequency component typically is less than 2 mA/MHz, with OE at VIH.

2.ICC active while Embedded Algorithm (program or erase) is in progress.

3.DC test conditions: VIL = 0.3V, VIH = VCC - 0.3V
