NOTES:
1.
Typical value for t
WHWH
1
is 7μs.
2.
Typical value for t
WHWH
2
is 0.4 sec.
3.
Guaranteed by design, but not tested.
4.
Typical value is 36 sec. The typical chip programming time is considerably less than the maximum chip
programming time listed, since most bytes program faster than the maximum program times listed.
