AC CHARACTERISTICS
Erase and Program Operations
Notes:
1.
Not 100% tested.
2.
See the “Erase And Programming 32-byte Performance” section
for more information.
3.
For 1–16 words/ 1–32 bytes programmed.
4.
Effective write buffer specification is based upon a 16-word/
32-byte write buffer operation.
5.
Word/Byte programming specification is based upon a single
word/byte programming operation not utilizing the write buffer.
6.
When using the program suspend/resume feature, if the suspend
command is issued within tPOLL, tPOLL must be fully re-applied
upon resuming the programming operation. If the suspend
command is issued after t
POLL, tPOLL is not required again prior to
reading the status bits upon resuming.
