There are no special requirements for the power-down sequence. All power supplies can be shut down at
the same time.

and temperature conditions. These values are derived from the i.MX25 with core clock speed up to
400 MHz. Additionally, no power saving techniques such as clock gating were implemented when
measuring these values. Common supplies are bundled according to the i.MX25 power-up sequence
requirements. Peak numbers are provided for system designers so that the i.MX25 power supply
requirements are satisfied during startup and transient conditions. Freescale recommends that system
current measurements are taken with customer-specific use-cases to reflect the normal operating
conditions in the end system.
