NOTES:
1.
Typical values measured at T
= +25 °C and nominal voltages. Assumes corresponding lock-bits are not set. Subject to
change based on device characterization.
2.
Excludes system-level overhead.
3.
These performance numbers are valid for all speed versions.
4.
Sampled but not 100% tested.
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 (t
