10.3.10 DC Programming Specifications

The following table lists guaranteed maximum and minimum specifications for the voltage and temperature ranges: 4.75V to 5.25V

and -40°C ≤ T

≤ 85°C, or 3.0V to 3.6V and -40°C ≤ T

≤ 85°C, respectively. Typical parameters apply to 5V and 3.3V at 25°C and

are for design guidance only.

Note

9. The 50,000 cycle flash endurance per block will only be guaranteed if the flash is operating within one voltage range. Voltage ranges are 2.4V to 3.0V, 3.0V to 3.6V

and 4.75V to 5.25V.

10. A maximum of 36 x 50,000 block endurance cycles is allowed. This may be balanced between operations on 36x1 blocks of 50,000 maximum cycles each, 36x2 blocks

of 25,000 maximum cycles each, or 36x4 blocks of 12,500 maximum cycles each (to limit the total number of cycles to 36x50,000 and that no single block ever sees

more than 50,000 cycles).

For the full industrial range, the user must employ a temperature sensor user module (FlashTemp) and feed the result to the temperature argument before writing.
