Polyphase metering MCU with seven 24-bit sigma-delta ADCs
The Texas Instruments MSP430F6779AIPEU is a 16-bit MCU built around the MSP430 CPUXV2 core running at 25 MHz, with 512 KB of Flash program memory and 32 KB of RAM. Its defining feature is the set of seven 24-bit sigma-delta analog-to-digital converters — purpose-built for polyphase energy metering, power-quality monitoring, and multi-channel sensor acquisition where simultaneous sampling matters.
The 25 MHz core speed runs real-time energy calculations across three phases plus neutral without a separate DSP.
Where it fits — industrial metering and control
Sourcing and lifecycle note
The lifecycle record shows an end-of-life (EOL) status alongside an active status entry — a discrepancy that means the part may be in its last production window or already phased out by Texas Instruments. No official successor order code is listed. Plan for a last-time-buy if a production run is still open, or evaluate a pin-compatible migration path within the MSP430F6xx family.
