NOTES:

All currents are in RMS unless otherwise noted. Typical values at nominal VCC, TA = +25°C.

ICCES and ICCWS are specified with device de-selected. If device is read while in erase suspend, current draw is ICCR. If the

device is read while in program suspend , current draw is ICCR.

Erases and Writes inhibited when VPP < VPPLK, and not guaranteed outside the valid VPP ranges of VPPH1,VPPH2. or VPPH3.

Sampled, not 100% tested.

Automatic Power Savings (APS) reduces ICCR to approximately standby levels in static operation (CMOS inputs).

Applying VPP = 11.4V–12.6V during program/erase can only be done for a maximum of 1000 cycles on the main blocks

and 2500 cycles on the parameter blocks. VPP may be connected to 12V for a total of 80 hours maximum. See Section 3.4

for details.
