AM2434: Sample vs. Production Device

Mari Tsunoda
Expert 5726 points
Part Number: AM2434


Hi Team,

My customer has a question about the differences other than functionality between mass-produced devices and sample devices (EVM).

The devices used in mass production are different from the devices provided in the sample products, including the production prototypes, but I have heard that there are no problems with the devices, only that the number of cores is different.
Is it correct to assume that power consumption, etc. would be the same if the cores are not used? Is there any way to disable the cores that are not used by default?
(They are testing power consumption, etc. for electrical evaluation with different product names from mass production and want to make sure that the power consumption is the same, including functionality, because it is completely meaningless as a test if the power consumption is different due to the different number of cores.)

Best regards,

Mari

    All of our EVMs use the preproduction "x" parts superset devices (as the silicon device has not RTM'd yet). Customers can apply custom SW configurations to "disable" core/IP/modules that's in the superset device as described in the device TRM. Power consumption depends on customer HW implementations, as ICs, and board BOMs may require more or less power than the EVM, but the estimated power consumption from the silicon will be the same. Depending on subset device required, customers should operate and configure the superset device for a better power consumption analysis.
