MSP430F67791: Does the Advanced DLMS features can be added into the 16-bit EVM

Hi,

There is DLMS COSEM Library which can be used on MSP430F67791. However, for the advanced DLMS function, I think it is hard to achieve on this MCU and the limitation would be the RAM size.

HI,

Well, I am getting the below information related to the DLMS.

The DLMS protocol stack typically requires 50-100 KB of Flash and 5-10 KB of RAM (depending on protocol feature trimming).

The MSP430F67791 offers 128 KB of Flash + 8 KB of RAM, which is theoretically sufficient for basic DLMS functionality. However, scenarios requiring full security encryption (e.g., AES-128) or multi-protocol integration (e.g., TCP/IP) may necessitate further optimization of memory allocation. 

So, I think the limitation would be the RAM size.

Hi,

If the security encryption is talking as the AES-128 than it is a hardware component. But it also could refer to other security encryption functions which may require from both software and hardware aspect.
