Lifecycle

Status: Active and widely used in production designs; not near discontinuation based on current industry status

Direct package alternative: MSP430FR6979IPZ (same silicon in tray packaging)

Close family alternatives (feature/memory/package variations; verify pin compatibility and LCD/ADC needs):

- MSP430FR6972 (same series, different memory/peripheral mix)

- MSP430FR6977 (same series, feature set variations)

- MSP430FR6989 (same FRAM class, larger feature set with similar CPU, commonly available in LQFP)

- MSP430FR6987 / MSP430FR6983 (family variants; check LCD/ADC requirements)
