3.13.3 Page Erase Timing
The time required to erase a 4 Kbyte program or 1 Kbyte data Flash logical page is calculated using the
formulas:
Eqn. 22
Eqn. 23
3.13.4 Page Erase Verify Timing
The time required to verify that a program Flash page is erased depends on the location of the first
non-blank word. The time required for the operation is calculated using the formula:
Eqn. 24
The time required to verify that a data Flash page is erased is calculated using the formula:
Eqn. 25
3.13.5 Programming Timing
Programming time is dependant on the fIPS and fNVMOP frequencies, and is calculated for a single word
using the formula:
Eqn. 26
Burst programming can be utilized with the program Flash, where up to 32 words in a row can be
programmed consecutively by keeping the command pipeline filled. The time to program a consecutive
word is calculated using the formula:
Eqn. 27
Therefore, the time to program a 32-word row is calculated using the formula:
Eqn. 28
Note that burst programming is more than 2 times faster than single word programming.
3.13.6 Data Signature Timing1
The time required to perform a data signature command is dependant on the number of words or
half-words compressed during the operation, and is calculated using the formula:
Eqn. 29
1. This feature is not available on mask set L49P and L47W devices.
