Notes
11. The 50,000 cycle flash endurance per block is guaranteed if the flash is operating within one voltage range. Voltage ranges are 2.4 V to 3.0 V, 3.0 V to 3.6 V,
and 4.75 V to 5.25 V.
12. A maximum of 36 × 50,000 block endurance cycles is allowed. This may be balanced between operations on 36 × 1 blocks of 50,000 maximum cycles each, 36 × 2
blocks of 25,000 maximum cycles each, or 36 × 4 blocks of 12,500 maximum cycles each (and so forth to limit the total number of cycles to 36 × 50,000 and that no
single block ever sees more than 50,000 cycles).For the full industrial range, you must employ a temperature sensor user module (FlashTemp) and feed the result to
the temperature argument before writing. Refer to the application note, Design Aids — Reading and Writing PSoC
