ARM7TDMI: Power dissipation Vs Frequency

Prashant

Hi

I am working on ARM7TDMI  Please help me to understand  the following points:

1.  how does the current drawn by the processor with respect to the operating frequency(please mention the current values).

2. Please specify the ideal current drawn by the processor with no workload.

3.  What is maximum current that can be drawn by the arm core?

Thanks and Regards

    The ARM7TDMI sold by ARM is just the "blueprint" for a processor, a source code description for the processor logic.

    ARM's silicon partners turn this into a physical silicon design, but they can all make different choices about how they do this. The power characteristics depend on many things - silicon process, silicon library choice, synthesis target frequency, etc, etc.

    There is no "standard" behavior for an ARM7TDMI - it depends on the specific chip you are using. You need to ask this question to a specific chip vendor.
