LAUNCHXL-CC1352R1: HELP with our First Design!!!

Prodigy 20 points
Part Number: LAUNCHXL-CC1352R1
Other Parts Discussed in Thread: CC2642R, , LPSTK-CC1352R, BOOSTXL-ULPSENSE, BOOSTXL-SHARP128, BOOSTXL-CAPKEYPAD, CC1352R

We are starting a New development for an Oil & Gas Valve Automation Field Application that requires battery independence for 5+ years in the field.

On it's first version, this is a small system that will monitor 12 Digital input signals and control 12 outputs: 10 indicating LED's and 2 solenoid valves (12v). We would like the Product to have a Real Time Clock to time-log the input signals events and also have Bluetooth Low Energy communication capabilities for occasional connection by the Operators when visiting the site to monitor Battery Status, update configuration (name, clock, Valve Tag, etc) and download any available Log information, as well as being able to force an output, for example.

Regarding power, we are considering a "Battery Pack" with 5 to 10 of 3.6v, 2.4A-H Li-Ion Batteries (AA-Size, EaglePicher PT-2100 or similar) could be the power source for the Product. (Split in two voltages: 3.6x4=14.4v for the solenoid and the rest to power the Product at 3.6V)

It is very important that the Product monitors the "Battery Pack" Status and if this goes below a threshold in either of the voltage buses, an action is taken with one of the solenoids (valve closing) to set the Product in a LOW BATTERY Mode at a Safe Process State.

We would like the product to comply with Functional Safety requirements if possible.

This is a small Block diagram of this product concept.


Could you please help us with your recommendation for the best fitted TI product(s) for such application?

Thanks in advance for your support.

Best Regards,

Arturo Trevino

    For MCU in your application, you can consider MSP432P411xT which should have enough GPIO. For BLE module, you can use CC2642R which you can find on TI EVB LAUNCHXL-CC26x2R.

    Hope you can help us put together this idea.

    We just purchased from Digikey the following for our development team:

    3 x LAUNCHXL-CC1352R1

    3 x LPSTK-CC1352R

    3 x BOOSTXL-IOBKOUT

    3 x BOOSTXL-ULPSENSE

    3 x BOOSTXL-SHARP128

    2 x BOOSTXL-CAPKEYPAD (only 2 were available in stock)

    Let me know if you think this is an appropriate set for what we want to develop, or if you would recommend to add something else?

    Thanks!!!

    Hi,

    The CC1352R1 can operate in  Sub1GHz and Bluetooth as demonstrated by the LPSTK-CC1352R. For project or product prototyping do not use the LPSTK, you have limited options on what you can add using LPSTK. Rather use the Launchpad version. TI has solutions for BMS.

    I suggest you think this thoroughly before you buy anything.

    Those kits are fine for BLE part but I don’t think CC1352R has enough GPIO for your application. I suppose you still need extra MCU such as MSP432 to do data aggregation.
