NOTES:

1. Typical values measured at TA = +25 °C and nominal voltages. Assumes corresponding lock-bits are

not set. Subject to change based on device characterization.

2. These performance numbers are valid for all speed versions.

3. Sampled but not 100% tested.

4. Excludes system-level overhead.

5. These values are valid when the buffer is full, and the start address is aligned on a 32-byte boundary.

6. Effective per-byte program time (tWHQV1, tEHQV1) is 6.8 µs/byte (typical).

7. Effective per-word program time (tWHQV2, tEHQV2) is 13.6 µs/word (typical).

8. Max values are measured at worst case temperature and VCC corner after 100k cycles (except as

noted).

9. Max values are expressed at -25 °C/-40 °C.

10.Max values are expressed at 25 °C/-40 °C.
