Description
PROGRAM/ERASE Power Supply: Supplies power for Program and Erase operations. VPP can
be the same as VCC (2.7 V to 3.6 V) for single supply voltage operation. For fast programming at
manufacturing, 11.4 V to 12.6 V can be supplied to VPP. This pin cannot be left floating. 11.4 V to
12.6 V can be applied to VPP only for a maximum of 1000 cycles on the main blocks and 2500
cycles on the parameter blocks. VPP can be connected to 12 V for a total of 80 hours maximum
(see Section 13.0, “VPP Program and Erase Voltages” on page 63 for details).

Warning:
Stressing the flash memory device beyond the Absolute Maximum Ratings in Table 11 can cause
permanent damage. These ratings are stress ratings only.

Notes:
1.
Minimum DC voltage is –0.5 V on input/output pins. During transitions, this level might
undershoot to –2.0 V for periods <20 ns. Maximum DC voltage on input/output pins is
VCC +0.5 V which, during transitions, might overshoot to VCC +2.0 V for periods <20 ns.
Maximum DC voltage on VPP might overshoot to +14.0 V for periods <20 ns.
VPP Program voltage is typically 1.65 V to 3.6 V. Connection to a 11.4 V to 12.6 V supply
can be done for a maximum of 1000 cycles on the main blocks and 2500 cycles on the
parameter blocks during program/erase. VPP can be connected to 12 V for a total of 80
hours maximum.
