FPGA Selection Help

[yavuz17]

Hello all forum members, I have a question.

I'm student at ITU Istanbul Technic University - Electronics & Communication Engineering.

I want to Design PCB for my ( Commercial and Academic ) project I need to use SoC for it.
I decided to buy from local supplier here is the link

<a href="https://fevaris.com/soc-system-on-chip/27-xc7z020-1clg400c-xilinx-soc-entegre"> XC7Z020-1CLG400C, Xilinx SoC</a>

after some research I find this version of this SoC on mouser

<a href="https://www.mouser.com.tr/ProductDetail/Xilinx/XC7Z020-L1CLG400I"> XC7Z020-L1CLG400I Xilinx | Mouser Turkey </a>

My question is what is the difference between these part ? Is there a critical difference between them ?

This is the ordering information section of Xilinx Zynq 7000 series datasheet. But I don't find my answer

To summarize my question:

What is the difference between, Is there a critical difference between them ?

XC7Z020-1CLG400C and XC7Z020-L1CLG400C​

Thanks in advance

Thank you so much. I have a new question. Design that XC7Z020-1CLG400C based can be used for XC7Z020-L1CLG400C ? Do I need any change ?

read the data sheet. maybe it needs a different core voltage. maybe it’s a bit slower.
