MSP430F6736A: interface it with a SD card

Part Number: MSP430F6736A
Other Parts Discussed in Thread: MSP430FR5994

Hello Team,

Posting on behalf of my customer:

I'm planning to use MSP430F6736A and interface it with a SD card.
According to this: Then target="_blank">https://www.ti.com/lit/an/slaa281c/slaa281c.pdf?ts=1674018757018&ref_url=https%253A%252F%252Fwww.google.com%252F
Then transfer the data stored in the SD card to a laptop via CC2564B bluetooth module and MSP430xxxx.

My question is :
1. Is this circuit configuration possible?
2. As per my project, I plan to use MSP430F6736A in LPM 3.5 for most of the time and use active mode whenever needed. Since the CC2564B is interfaced with MSP430, MSP430 provides power to both SD card module and CC2564B
1. During LPM 3.5 will the MSP430 supply enough power to both SD card module and CC2564B to keep it active ?
3. How does the CC2564B work, will it be able to scan, detect, pair and send data to my laptop?

Regards,
Renan

    Hello Renan,

    this is a quite an old app note, but it was accurate at the time of publication. For the same type of SD card it should be valid, but we haven't tested with newer SD card standard. Theyc an also check out the example for MSP430FR5994 and check the schematic on its Launchpad : https://dev.ti.com/tirex/explore/node?node=A__ALBhfl55ewg.hLTVI74EAQ__msp430ware__IOGqZri__LATEST 

    Note: the MSP430FR5994 LP no longer comes with SD card slot as that particular housing  is no longer manufactured. 

    LPM3.5 only has RTC + LFOSC active, and it locks in pin states. The core of the device is off, so I wouldn't recommend this LPM for keeping another device powered. 

    For questions about the CC2564B, please make a new thread about that device.
