MSP430FR2111: Making board to program RLL (VQFN-24) package

Alex Beloff

Part Number: MSP430FR2111

Since I couldn't find anything ready for programming MSP430FR2xxx RLL packages, I'm trying to make my own. The idea is to make a board with JTAG, solder VQFN-24 chip and program it. And when it's done, desolder it and put into an application board.

Here's what I came up with (I hope it's clear with net names):

I wonder if that's correct. Can someone please check? If it is, I'll make a PCB layout.

Thank you,
Alex

Hi Alex,

I have a look for this sch, it seems OK.

And another suggestion: desolder is too difficult and and have some risk, maybe you can try to use a socket.

Thanks!

Thank you!

I've searched everywhere I could. I couldn't find such socket anywhere. If you do know where to get it, I'd really appreciate it!

Hi Alex,

Generally speaking, you can customize the socket with vendor.

Thanks!

Well, I guess I'm too small for them.

Last question - Can you please suggest on C2? Should this be a polarized cap or is it possible to use mlcc?

Thank you for your help!
