How many Energy Consumption PSoC4 4200 BLE

user_502863490 Mar 28, 2017 12:15 AM

How many Current Consumption of PSoC4 4200 BLE chip?(I think using CY8C4248FNI-BL553)

By data sheet, I know active mode current is 1.7mA(3MHz),

but I want know current @ M0 Core running Max Frequency 48MHz.

I want total (max) current consumption(BT + M0 + Programmable block), and I can't find 'M0' current.

->where should I read?

->Any one measure real device? Please teach me the reference value?

Thank you.

This is a bit complicated to answer: the current depends on active components and their clock frequency, debug interface, radio state etc.

That is where the development kits are good for.

Thank you for your reply, Bob.

OK. I get your answer, and I have to measure current by dev kit.

In other hand, many processor's data sheet shows consumption current like "XX.X uA/MHz", and I want like that data.Because I want to estimate about/max current of the processor.



Sorry.The data sheet says "Preliminary" state. So I think I cant get the data yet now.

When you look at a component's datasheet you will find a "XX.X uA/MHz" note. But because it is up to you which and how many components you use this information cannot be given for the complete chip.
