The MSP430F67641IPNR integrates three 24-bit sigma-delta ADCs for energy measurement and precision sensor front-ends.
The 25 MHz core clock supports real-time control loops that read the sigma-delta converters.
The core processor runs at 25 MHz. At that speed the CPUXV2 core can execute a multiply-accumulate in a single cycle using the hardware multiplier, which is the typical operating point for energy-computation firmware that reads the sigma-delta converters.
