This disclosure relates to a system that includes a centralized trim controller and a non-volatile memory that includes a trim sector configured for hosting trim data for one or more peripherals. The trim controller is configured to receive, for each of the one or more peripherals, trim values of the one or more peripherals from the trim sector of the nonvolatile memory, and provide the trim values to the one or more peripherals. Some trim values are updateable by receiving a password at the trim controller. If the password is valid, a timeout counter is initiated, during which time the trim value is updateable.
