NOTES:
1. Typical values measured at T
A
= +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 (t
WHQV1
, t
EHQV1
) is 6.8 μs/byte (typical).
7. Effective per-word program time (t
WHQV2
, t
EHQV2
) is 13.6 μs/word (typical).
8. Max values are measured at worst case temperature and V
CC
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.
