RT600 power consumption

[xuzhao09026]

hello,

we want to select PMIC for RT600 and would like to know how to estimate the max current from VDDCORE/VDD1V8.

1. The datasheet has table 24-26 for VDDCORE but I am not sure what the difference is.

2. I can't find the VDD1V8 consumption in active mode.

Please kindly advise.

Hello Xuzhao09026,

The power consumption for the cores is available as VDDCORE. The difference within these tables is the clock frequency and core voltage. The difference between the tables are whether the DSP is Active (table 26) or not (table 24 and 25), as well as how the maximum current is measured, either trough an enhanced while loop or with another benchmark.

However, the power consumption from VDD1V8 by itself is not supplied other than in Deep Sleep mode. The power necessary by VDD1V8 would depend on the analog circuits powered and their use-case, so it’s hard to provide a measurement without tying it to a use case.

My apologies for the inconvenience.

Regards,
Gustavo
