MSP430F5528: Wireless Connectivity Options

Ian Kibblewhite
Prodigy 10 points
Part Number: MSP430F5528
Other Parts Discussed in Thread: LMT70, CC3100, LMT70EVM, CC2560, , CC3120MOD, CC2640R2F-Q1, CC3120, CC2640R2F, BOOST-CC2564MODA, MSP430F5529, CC31XXEMUBOOST

We have evaluated the LMT70 temperature transducer with the MSP430F5528 using the LMT70EVM and it works great for our application.  We need a wireless connection and have both BT & WiFi connectivity options with our product uP controller.  I'd like some guidance on the best option for our product and have been looking at the CC3100 and CC2560.

Our temperature measurement requirements are fairly basic.  We will only have one device connected to our product uP controller at a time and all we want to do is periodically wakeup, read the LMT70 through the ADC of the MSP430F5228 (or similar), perform some calibration scaling and upload a temperature reading at a rate of 1-60 per min.   We would also like to be able to download  a new calibration lookup table occasionally if possible after performing a calibration process.  Preferably the temperature probe with MSP430 and connectivity electronics could work at 120C.

We are looking for a minimum power consumption, simple, seamless, reliable connection solution.  What would you recommend?

    Hello Ian,

    Thank you for your detailed post. For combined BT and Wi-Fi capabilities, we offer the Wi-Link 8 devices, but they are typically used with host application processors (running Linux, Android, etc.) and not microcontrollers. Thus, you may need to use two different devices for your application. Since the MSP430F5528 will be your host microcontroller, I'd recommend using our CC3120 (offered in module format as CC3120MOD) as the Wi-Fi network processor and the CC2640R2F for the BT/BLE. Unfortunately, the highest operating temperature is only 105C for the CC2640R2F-Q1 variant.

    The CC3100 and the CC2560 are also good options but are older devices. We offer BoosterPacks that can plug into our MSP430F5529 LaunchPad for quick development. For example, the BOOST-CC2564MODA board is compatible with the CC31XXEMUBOOST board.

    Here are some links that should be helpful regardless of what device you pick.

    Now, our SimpleLink MSP432 may be overkill for your application, but it may be the most seamless solution for adding support for these Wi-Fi and BT devices. You can learn more about our SimpleLink MCU platform at the links below.
