PAL16R6AM: Power Consumption over frequency

Christian Colon Ortiz
Prodigy 10 points

Part Number: PAL16R6AM

I am working on a product redesign where the half power version of this part (PAL16R6A-2M) was used. 

I would like to use the not obsolete, PAL16R6AM as an alternate.

Could you provide information of power consumption over frequency for both parts?

What are the conditions for max power consumption?

    Christian,
    I searched for information on the dynamic component of the current. Unfortunately, I was not able to locate any characterization or information for these devices.
    Typically digital devices will have 2 components of current. The static ICC, and then the dynamic portion based on frequency of operation.
    For the static portion, the faster version is twice the current of the low power version.
    This can be seen with the ICC parameter.
    Icc is max of 180mA for the high speed version, and 90mA for the standard speed.
    This portion of the current can double with the switch.

    The dynamic portion likely will be similar, but I expect that it will not be double. This will also have a component of the load on the output.
    If applying the same application and clock rates, it should be safe to double the total power.
