Note:

1. The input test environment is done with 0.1 V

overdrive than this. V

testing may use different voltage values, but must correlate results back to these parameters.

Note:

1. A reset latency of 20 µs will occur if a reset procedure is performed during a programming or erase operation.

AC Waveform for Reset Operation

Notes:

1. Typical values measured at T

2. Excludes system-level overhead.
