Should I shield my type C USB?

@copilot Should I shield my type C USB?

copilot

Shielding a USB Type-C connector, like the TYPE-C-31-M-12 in your project, is a good practice to prevent electromagnetic interference (EMI) and improve signal integrity. This is particularly important if you're dealing with high-speed data or if the device will be used in environments with a lot of electronic noise.

Benefits of shielding USB Type-C:

Reduces EMI: Provides protection against external electromagnetic fields which can interfere with the data signals on the USB lines.
Improves Signal Integrity: Maintains the quality of the transmitted signal by minimizing the risk of interference that can cause data errors.
Ground Loop Protection: Helps in preventing potential ground loops that can affect performance.

Since your project involves connections that include high-speed data lines, it would be advantageous to utilize the shielding pins (like SHIELD in J1) appropriately:

Connect the shield pins: Make sure that the shield pins are connected to a reference ground on your board (such as the GND plane) to ensure the effectiveness of the shielding.

Before implementing, consider the intended environment and the potential for interference. If you have any more specific conditions or requirements, feel free to share them!

@copilot by putting a resistor between VDD and RST it act like a high pull resistor keeping RST high right?

copilot

Yes, that's correct! By connecting a resistor between the VDD (supply voltage) and the RST (reset) pin, you create a pull-up resistor configuration. This resistor "pulls up" the RST pin to a high level (VDD) under normal conditions, which keeps the reset line deactivated.

When the RST pin is required to be low (to reset the device), an external device can pull it low, overcoming the pull-up resistor.

For your specific project:

Connect $VDD$ to a resistor, and then connect the other side of the resistor to $IC1:\sim RST$ .

If you need help calculating the appropriate resistor value or have related questions, feel free to ask!

I put a 10kOhms resistor

copilot

A 10 kΩ pull-up resistor is a commonly used value for pull-up configurations and should work well for most applications.

With a 10 kΩ resistor, you'll have a good balance between current consumption and noise immunity. The resistor value is generally not critical, but using a higher value might cause the reset line to be more susceptible to noise, while a lower value might result in higher power consumption.

If you have any more specific concerns or additional questions, feel free to let me know!

asystra

@copilot I want to connect J1 with I2C so that the the USB data can be transform into UART. I use USB 2.0 standard and J1 will not deliver power to anything J2 will be responsible of that

copilot

To facilitate communication between USB and UART using the USB 2.0 standard, we'll use the MCP2221A-I/ML as a USB-to-UART/I2C converter. Based on your input, here is a suggested connection plan for integrating USB functionality with I2C/UART:

Connecting J1 (USB Type-C Connector) to IC1 (MCP2221A):
- Connect J1:DP1 to IC1:D-.
- Connect J1:DN1 to IC1:D+.
- Connect J1:GND to a common ground.
Setting up IC1 for I2C/UART:
- Connect IC1:VUSB to +3.3V (locally bypassed with a high-quality ceramic capacitor as recommended).
- Connect IC1:VSS to the common ground.
I2C Setup:
- Use IC1:SDA and IC1:SCL for the I2C bus. Connect these pins to your I2C-enabled device.
UART Setup for Data Conversion:
- Utilize IC1:URx and IC1:UTx for UART communication. These should be connected to corresponding UART devices.
Power Considerations:
- Since J1 is not used for power delivery, the VBUS pins are not connected. The power for the MCP2221A comes through IC1:VUSB supplied by the +3.3V net.

Would you like to proceed with these connections, or is there anything else you'd like to modify or inquire about?
