1. Characteristics are valid both for Data Flash and Code Flash, unless specified in the characteristics column.

2. Actual hardware operation times; this does not include software overhead.

3. Typical program and erase times assume nominal supply values and operation at 25 °C.

4. Typical End of Life program and erase times represent the median performance and assume nominal supply values.

Typical End of Life program and erase values may be used for throughput calculations. These values are characteristic, but

not tested.
