Appendix A Electrical Characteristics
A.5.1.1
The programming time for single word programming is dependant on the bus frequency as a well as on the
frequency f¨
A.5.1.2
Generally the time to program a consecutive word can be calculated as:
For theQ16 and Q32 device flash arrays, where up to 32 words in a row can be programmed consecutively
by keeping the command pipeline filled, the time to program a whole row is:
For the Q64,Q96 and Q128 device flash arrays, where up to 64 words in a row can be programmed
consecutively by keeping the command pipeline filled, the time to program a whole row is:
Row programming is more than 2 times faster than single word programming.
A.5.1.3
Erasing either a 512 byte or 1024 byte Flash sector takes:
The setup times can be ignored for this operation.
A.5.1.4
Erasing a NVM block takes:
This is independent of sector size.
The setup times can be ignored for this operation.
