What sets it apart from the general-purpose MSP430 line is the integration of six independent 16-bit sigma-delta analog-to-digital converters, purpose-designed for polyphase energy metering and multi-channel precision measurement.
Texas Instruments lists the MSP430F47126IPZ as an active product. For a metrology platform that may run for a decade in the field, that matters.
Both share the same six 16-bit sigma-delta ADC core, the same 100-pin LQFP package, and the same peripheral set. The choice comes down to firmware size and data buffer requirements.
