Times
Notes: 1. Make each time setting in accordance with the program/program-verify flowchart or
erase/erase-verify flowchart.
2. Programming time per 128 bytes (Shows the total period for which the P1 bit in the
flash memory control register 1 (FLMCR1) is set. It does not include the program
verification time.)
3. Block erase time (Shows the total period for which the E1 bit in FLMCR1 is set. It does
not include the erase verification time.)
4. Maximum programming time value
tp (max) = Wait time after P1 bit setting (tsp)
× maximum program count (N)
(tsp30
+ tsp10) × 6 + (tsp200) × 994
5. Relationship among the maximum erase time (tE (max)), the wait time after E1 bit
setting (tse), and the maximum erase count (N) is shown below.
tE (max) = Wait time after E1 bit setting (tse)
× maximum erase count (N)
6. The minimum times that all characteristics after rewriting are guaranteed. (A range
between 1 and minimum value is guaranteed.)
7. The reference value at 25
°C. (Normally, it is a reference that rewriting is enabled up to
this value.)
8. Data hold characteristics when rewriting is performed within the range of specifications
including minimum value.
