MSP430FR5739: Bare Die Solution

Jerry Leung

Part Number: MSP430FR5739

Hello,

I have contacted our local rep but also want to post my question here as well since to try things in parallel.

We are looking specifically at the MSP430FR5739 bare die solution available at Digikey but I don't see any relevant information about this on the TI website so I want to verify and see whether or not this is an active product. If so, could we get the die map information?

https://www.digikey.com/product-detail/en/texas-instruments/MSP430FR5739CY/296-35655-ND/3878791

https://www.ti.com/product/MSP430FR5739

Secondly, the main purpose is for us to have an unique identifier as suggested by this E2E post.

https://e2e.ti.com/support/microcontrollers/msp430/f/166/t/19506?MSP430-unique-chip-number#pi320995=2

To access the information, can we simply read it just through the 2-wire Spy-Bi-Wire interface? Would there be any additional wire-bonds to pins we should consider?

Thanks for the help in advance,

Jerry

Hi Jerry,

Could you describe your detailed about project requirements? Why do we need bare die?

If you just want to obtain the unique information of the device to identify the MCU, you can directly read and use the Lot/wafer ID, Die X position and Die Y position of the TLV inside the MCU.

Best Regards

Hi Johnson,

The main reason we are looking for a bare die solution is we are looking to wirebond this directly and avoid magnetic interference caused by the packaging materials. If necessary please feel free to call or email me directly, I would like to lock in this design by today if this is a valid solution for us.

Thanks and best,

Jerry
