CC3220: CC3200SF: Minimum schematic requirements for standalone PCB design?

SWAROOP R SADARJOSHI

Part Number: CC3220

Hello all,

I want to develop a standalone PCB for CC3220SF SimpleLink™ Wi-Fi® and IoT, Single-Chip Wireless MCU, I have the following queries:

1. What are the minimum components required to develop and design a standalone PCB for CC3220SF?

2. Which type of power connection is suitable when using 5 parallel cell of 1.2V (i.e. Vin = 6V) NiMH/NiCad chemistry as power supply? VBAT Wide-Voltage Connection type or Preregulated 1.85-V Connection?

3. If "Preregulated 1.85-V Connection" is preferred then which is the best possible way to obtain 1.85V from 6V (5 parallel cells as mentioned above)( any particular TI IC)?

4. How many layers PCB is preferred for CC3220SF? Is a two layer PCB advisable or not?

5. What is best way to design an antenna for the CC3220SF for the PCB?

6. What all precautions and measures I need to take care of for designing PCB for CC3220SF?

Thanks and regards

Hi Swaroop,

1. See the device datasheet for a minimal schematic and the Hardware Design Guide: processors.wiki.ti.com/.../CC3120_&_CC3220_Hardware_Design_Review

2. Wide-Voltage connection is recommended

3. N/A, Wide-voltage

4. 4 layers would be preferred. See Layout Guide

5. It would be best to use the CC3220MOD and follow the antenna design on the LaunchPad

6. See processors.wiki.ti.com/.../CC3120_&_CC3220_Hardware_Design_Review
and processors.wiki.ti.com/.../Hardware_Design_Checklist

Hope this helps,
Kevin

Thanks a lot Kevin for the reply.

After going through your reply I have opted to go ahead with CC3220MODASF12MONR for my product.

My basic requirements are high level of security and easy to build prototype PCB with the module.

I have few more queries;

1. What are minimum requirements for standalone PCB development for CC3220MODASF12MONR?

2. Is the TM4C1294NCPDTI3R (and other components as listed on the CC3220MODASF LaunchPad™ Development Kit) are must if I want to burn code/program the CC3220MODASF12MONR on my custom PCB?

3. Do I need to build a custom PCB with schematic similar to CC3220MODASF LaunchPad™ Development Kit in order to have the ability to burn code/program the CC3220MODASF12MONR along with my other requirements?
