Driving internal pull-down resistor.
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 (and so forth to limit the total number of cycles to 36x50,000 and that no single block ever
sees more than 50,000 cycles).
The CY8C25xxx/26xxx family of PSoC devices uses an adaptive algorithm to enhance endurance over the indus-
trial temperature range (-40°C to +85°C ambient). Any temperature range within a 50°C span between 0°C and
85°C is considered constant with respect to endurance enhancements. For instance, if room temperature (25°C)
is the nominal operating temperature, then the range from 0°C to 50°C can be approximated by the constant value
25 and a temperature sensor is not needed.
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. Refer to the Flash APIs Application Note AN2015 at http://
