Electrical Characteristics
3.6.2.1.2
This applies only to the Flash, where up to 64 words in a row can be programmed consecutively, using burst programming by
keeping the command pipeline filled. The time to program a consecutive word can be calculated as:
The time to program a whole row is:
Burst programming is more than 2 times faster than single word programming.
3.6.2.1.3
Erasing a 512-byte Flash sector takes:
The setup time can be ignored for this operation.
3.6.2.1.4
Erasing a NVM block takes:
The setup time can be ignored for this operation.
