Section 18 Electrical Characteristics
3. Block erase time (Shows the period the E bit in FLMCR is set. It does not include the
erase verification time.)
4. To specify the maximum programming time (tP(max)) in the 32-byte programming
flowchart, set the max value (403) for the maximum programming count (N).
The wait time after P bit setting (z) should be changed as follows according to the
programming counter value.
Programming counter value of 1 to 4: z = 150 µs
Programming counter value of 5 to 403: z = 500 µs
5. For the maximum erase time (tE(max)), the following relationship applies between the
wait time after E bit setting (z) and the maximum erase count (N):
t (max)
E
=

(N)
To set the maximum erase time, the values of z and N should be set so as to satisfy the
above formula.
Examples: When z = 5 [ms]: N = 60 times
When z = 10 [ms]: N = 30 times
