Suggest MSP430 core controller for smart metering with OTA

Hello,

I would highly recommend the MSP430F6736A to be used in your smart meter. On the hardware side, you can purchase the EVM430-F6736 from the TI Store. On the software side, have you heard about our new Energy Measurement Design Center for MSP430 MCUs (MSP-EM-DESIGN-CENTER). You can read about it in the following thread. It will accelerate your development time and allow you to focus on the OTA code rather than the metrology code.

Thanks for the prompt reply james.

Can you please clear few points.

Is it possible to divide the code memory into two blocks and any of the two blocks can be accessed independently through a separate bootloader.

Let me clear my requirements :
For Firmware update over the air :
Suppose meter is functioning in the field and I want to update its firmware over the air.
I will transmit code into separate memory and will validate it.
Then I will write the code into its code memory, at different location than existing one, and will update a flag at separate memory.
Now, I will reset the device and while booting I will check on the flag and will start program execution from the address where I have written the new code.
But suppose, any problem occurs at any point of time, then I need to get back to my earlier code. So, I will update the flag again and reset the device again and will start program execution from the address of earlier code.

Is it possible with this micro. If yes please share details how to achieve it into this micro.

Please also share contact details of yours for any further help and contact for local support.

Thanks once again james
