You can find the PSoC 4 current consumption under different conditions and CPU frequencies from the respective device datasheets. Look for "DC Specifications" under the section "Device Level Specifications". Following table is an example from PSoC 4100S Plus device datasheet.
Although PSoC 6 has an active power advantage over PSoC 4, the latter has lower Deep Sleep currents. By properly switching between the power modes and using a variety of other techniques, you can easily design low power applications with PSoC 4. Please refer to the following application note for details:
This application note also contains a handy power estimator spreadsheet tool.
Thank you for the answer Nidhin.
The Psoc 4100S has a lower power consumption than older Psoc 4 devices.
But sadly there is no more a stop mode (mode where the core is using only a few tenth of nA waiting for an external event).
I will have to look at the single core Psoc 6 to see if a stop mode is available.
PSoC 6 doesn't have a stop mode. However, it has a hibernate mode which consumes only 300nA at 1.8 V. In addition, PSoC 6 has a separate backup domain which allows you to completely shutdown the external regulator powering the system (PMIC control), and then re-enable it upon an RTC / pin interrupt. Details can be found in the following application note;
Thank you for the information.
I will wait for the single core Psco6 to be available.
