Product details

What the 7×24-bit sigma-delta ADC means for your BOM

Its defining feature is the integrated set of seven 24-bit sigma-delta analog-to-digital converters, purpose-built for polyphase energy metering and precision measurement applications where you need simultaneous sampling on multiple channels.

Lifecycle and sourcing posture

That said, the MSP430F6xx series is a mature portfolio — TI's roadmap emphasis has shifted to the MSP430FRxx FRAM family for new metering designs. For production BOMs that need a second-source hedge, the pin-compatible MSP430F6779 (without the 'A' revision) is a drop-in alternative, though its firmware may need minor tweaks for errata differences.

Frequently asked questions

Is MSP430F67791AIPZR obsolete or end-of-life?

No — the product status is Active, meaning TI continues to manufacture it. No EOL notice has been issued for this order code.

What is the replacement for MSP430F67791AIPZR?

There is no direct official replacement listed. The pin-compatible MSP430F6779 (non-'A' revision) can serve as a second source, but verify firmware compatibility for any errata differences. For new designs, TI recommends evaluating the MSP430FRxx FRAM series, though those are not pin-compatible.
