Power Consumption of U1

how much power does u1 consume power?

Thought for 40 sec

To answer precisely, we use the HC32L110B6YA datasheet specs for supply current and multiply by your VCC. From the datasheet for U1:

At VCC = 3.3 V, typical supply current (all peripherals off) is:

Run in RAM, RCH clock:
- 4 MHz: IDD typ = 220 µA → P ≈ 0.73 mW
- 8 MHz: 400 µA → 1.32 mW
- 16 MHz: 740 µA → 2.44 mW
- 24 MHz: 1080 µA → 3.56 mW
- 32 MHz: 1400 µA → 4.62 mW
Sleep mode (all peripherals off), RCH clock:
- 4 MHz: 110 µA → 0.36 mW
- 8 MHz: 190 µA → 0.63 mW
- 16 MHz: 330 µA → 1.09 mW
- 24 MHz: 470 µA → 1.55 mW
- 32 MHz: 580 µA → 1.91 mW

Notes from the datasheet:

Currents depend on voltage, temperature, clock source/frequency, peripheral usage, I/O loading, code location, etc.
The above “Run in RAM” figures are at VCC = 3.3 V, VCAP = 1.55 V, RCH clock, peripherals off.
If running from Flash or enabling peripherals, currents are higher (datasheet provides additional tables).

If you tell me your intended clock frequency, supply voltage, and whether you’ll run from Flash or RAM (and which peripherals are enabled), I can quote the closest datasheet row and compute the corresponding power.

16 MHz Flash run

24 MHz RAM run

8 MHz Sleep mode

32 MHz Flash with ADC/SPI
