AC CHARACTERISTICS—Write/Erase/Program Operations
Notes:
1. Read timing characteristics during read/write operations are the same as during read-only operations. Refer to AC
2. Maximum pulse widths not required because the on-chip program/erase stop timer will terminate the pulse widths internally
3. Chip-Enable Controlled Writes: Write operations are driven by the valid combination of Chip-Enable and Write-Enable. In
4. Not 100% tested.
