AC CHARACTERISTICS Write Operations
NOTES
1 Read timing characteristics during erase and byte write operations are the same as during read-only operations Refer to
AC Characteristics for Read-Only Operations
2 Sampled not 100% tested
3 Refer to Table 3 for valid A
4 Refer to Table 3 for valid D
5 The on-chip Write State Machine incorporates all byte write and block erase system functions and overhead of standard
Intel flash memory including byte program and verify (byte write) and block precondition precondition verify erase and
erase verify (block erase)
6 Byte write and block erase durations are measured to completion (SR 7
