Question 23

Question 24

Answer 23

Answer 24

Can I program/erase/read the FLASH at the maximum temperature

limits continuously for the specified lifetime of the part?

Yes.

What modes of operation cause the most noise?

Program and erase modes cause a significant amount of EMI

(electromagnetic interference) and power supply noise due to the high

transient current demand of the charge pump. High accuracy ADC

(analog-to-digital) conversions may not be possible while the FLASH is

programming or erasing.
