capabilities.

1 Applying the maximum voltage results in maximum power consumption and heat generation. A voltage set point = (Vmin + the

supply tolerance) is recommended. This results in an optimized power/speed ratio. Operating a voltage of 1.2V and above will

reduce the overall lifetime of the part. For details, see i.MX 7Dual/Solo Product Lifetime Usage (AN5334).
