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.

@docbrown how much power does this component here consume?
@docdrown are you here?

To provide the power consumption information for a component, I need to know the specific component in question. Please provide the designator or part name from the list of components you provided earlier, and I'll provide the information you're looking for.
2y
@natarius, I assume you're referring to the HC32L110B6YA microcontroller. Unfortunately, I don't have the exact power consumption numbers for this specific microcontroller, but it belongs to the HC32L110 series, which is known for its low power consumption. To find the exact numbers, consult the datasheet: https://www.hdsc.com.cn/cn/Index/downloadFile/modelid/65/id/8/key/0
Remember that power consumption can vary depending on the microcontroller's operating modes, clock frequency, peripherals used, and specific settings.

@docbrown whats this component connected to?
My apologies for the confusion. For capacitor C3 (100nF non-polarized capacitor), the connections are as follows:
- Pin P1 of C3 is connected to SW1 (Net 2)
- Pin P2 of C3 is connected to Ground (Net 0)
In summary, C3 is connected between SW1 and Ground.
2y
Ah, I see you meant C3 now! Capacitor C3 is a 100nF non-polarized capacitor with the following connections:
- Pin P1 of C3 is connected to SW1 (Net 2)
- Pin P2 of C3 is connected to Ground (Net 0)
In summary, C3 is connected between SW1 and Ground.

@docbrown what does this component do?
As an AI, I cannot visualize the physical layout of the project. But based on the given netlist and components' information, the power wiring for VCC and GND is connected to the appropriate pins on components where necessary. However, please verify the connections against the datasheet and the design guidelines for each component to ensure the overall design is correct. If there are specific connections you're unsure about, feel free to mention them, and I'll provide information based on the available data.

please explain what C6 does.
2y
In the circuit, the capacitor C6 is connected to the 'Vcap' pin of the microcontroller U1, which typically handles voltage stabilization and noise reduction for the internal core voltage of the microcontroller.
The capacitance value is 4.7µF, suggesting that it's likely used for smoothing and filtering power supply fluctuations.
These are important facets of microcontroller operation because clean and stable power is necessary for accurate and stable operation of the microcontroller, especially when it's running at high frequencies.
As a reminder, connections are as follows:
- Connect U1:Vcap to C6:P1
- Connect C6:P2 to GND:P1
Please adjust this if your intent for this capacitor is different.

@docbrown how should I approach improving this project?
@lwcassid, the current crystal oscillator (X1) specified in the project is the ABM3C-32.000MHz-D4Y-T from Abracon LLC. This component has a frequency of 32MHz, which is a common choice for microcontrollers like the HC32L110B6YA. The datasheet URL for this oscillator is: https://abracon.com/Resonators/ABM3C.pdf
This oscillator seems suitable for the project, but always make sure you verify its compatibility with other components and confirm it meets your performance and accuracy requirements. If this oscillator does not meet your specific needs, consider alternatives with better stability, frequency tolerance, or operating temperature range that align with your application's demands. Don't forget to double-check the footprint and package size to ensure it fits your PCB layout!
2y
Great Scott, @lwcassid! To improve this HC32L110B6YA-CSP16 breakout board project, I suggest the following steps:
-
Double-check component selection: Ensure all chosen components are suitable for the desired functionality of your board, such as capacitors, resistors, and oscillators. Verify component ratings and confirm the availability of the parts.
-
Optimize power supply decoupling: Place the decoupling capacitors (like C1, C2, C3, and C4) close to the MCU's VCC and GND pins. This minimizes high-frequency noise and improves the stability of voltage supply.
-
Review PCB layout: Keep analog and digital routing separate, minimize ground loops, and maintain short trace lengths, especially for high-speed signals. Also, ensure impedance-controlled tracks for critical signals have the correct width.
-
Label the connectors: Assign meaningful labels to the connectors (like J1, J2, and J3) and create a visual representation of the pinout for straightforward usage.
-
Test point placement: Include test points to allow for easy debugging and testing of important signals and power rails during the bring-up phase of the board.
-
Documentation: Create documentation for the project that outlines the functionality, design choices, and any specific details that could be useful for future reference or optimization.
Lastly, seek feedback from experienced peers who can offer valuable insights and improvements to your design. Good luck!
