IERSS

Supply current, for slow erasing (low-power

programming mode)

VDDI/VPP/VDDE = MAX

IPPF

Supply current, for fast programming

† Dependent on JEDEC standard 8–1A.

NOTES: 20. Test results of erasing and programming with VPPL < VPP < VPPH are undefined.

21. Positive current flow is into the device.

22. Test supply voltage range: (4.5-V dc

≤ VDDI ≤ 5.5-V dc) and (3-V dc ≤ VDDE ≤ 3.6-V dc).

23. Device in read mode with OE enabled.
