Six 24-bit sigma-delta ADCs — the reason this chip exists
Its defining feature is the six 24-bit sigma-delta analog-to-digital converters — that peripheral set is what separates it from a general-purpose MSP430.
This part is officially obsolete per the manufacturer. If you have an active BOM line with this order code, you are looking at last-time-buy inventory or new-old-stock — no factory lead times, no guaranteed future availability. The procurement decision is straightforward: source what you can now, or qualify a replacement before the remaining stock dries up.
What the 25 MHz core and 256 KB Flash buy you
The 25 MHz CPUXV2 core is not a speed demon by modern standards, but it is more than adequate for the metering and measurement tasks this chip was designed for. The 256 KB Flash gives you room for a real-time operating system, a calibration table, and several firmware update slots if you use the Flash as program memory. The 16 KB RAM is tight for heavy data buffering — plan your DMA and ADC sample buffers carefully if you are logging all six channels continuously.
