Question:

What will happen to F-RAM if it is turned ON and OFF continuously? Is it required to meet the t_PU and t_PD timings?

Answer:

It is not necessary to meet the timings t_PU (Power-up to first access) and t_PD (last access to power down) during power up and power down. F-RAM can be turned ON and OFF continuously. As long as the V_DD slopes, measured at any point, meets the power-up ramp rate (t_VR) and power-down ramp rate (t_VF), and the voltage is monotonic during power up and power down, there are no issues. F-RAM will continue to function normally in the next power up.
