CHAPTER 23 ELECTRICAL SPECIFICATIONS ((A2) grade product)
Note 3.
(A2) grade product TA = −40 to +125°C
When guaranteeing the flash self programming, use the following formula to perform design such that the
sum of the power consumption of the device is less than or equal to the total loss PT (use at 80% or less of
the rated value is recommended).
• Total power consumption = VDD × {IDD − ∑IOH} + ∑{(VDD − VOH) × IOH} + ∑(VOL × IOL)
When guaranteeing the internal pull-up resistor, use the following formula to calculate its power
consumption, and add the result to the result above.
• Power consumption of internal pull-up resistor = Σ(VDD/RPU × VDD)
Remark During flash memory programming, IDD = 7.0 mA (MAX.).
