Notes:

1.

Voltages shown are specified with respect to VSS. Minimum DC voltage is –0.5 V on input/output signals and –0.2 V on

VCC, VCCQ, and VPP. During transitions, this level may undershoot to –2.0 V for periods < 20 ns. Maximum DC voltage on

VCC is VCC +0.5 V. During transitions, this level may overshoot to VCC +2.0 V for periods < 20 ns. Maximum DC voltage

on input/output signals and VCCQ is VCCQ +0.5 V. During transitions, this level may overshoot to VCCQ +2.0 V for periods

< 20 ns.

2.

Maximum DC voltage on VPP may overshoot to +14.0 V for periods < 20 ns.

3.

Program/erase voltage is typically 1.7 V – 2.0 V. 9.0 V can be applied for 80 hours maximum total, to main blocks for

1000 cycles maximum and to parameter blocks for 2500 cycles maximum. 9.0 V program/erase voltage may reduce

block cycling capability.

4.

Output shorted for no more than one second. No more than one output shorted at a time.

2.

In typical operation, the VPP program voltage is VPPL. VPP can be connected to 8.5 V – 9.5 V for 1000 cycles on main

blocks and 2500 cycles on parameter blocks.
