Notes:
1. The ranges given here are for power supplies only. The recommended input voltage ranges specific to each
2. All parameters representing voltages are measured with respect to GND unless otherwise specified.
3. VPUMP can be left floating during normal operation (not programming mode).
4. The input voltage may overshoot by up to 500 mV above the Recommended Maximum (150 mV in Direct
mode), provided the duration of the overshoot is less than 50% of the operating lifetime of the device.
6. Violating the VCC15A recommended voltage supply during an embedded flash program cycle can corrupt
the page being programmed.
