Product details

Why the 512-byte RAM matters more than the Flash count

That RAM budget is the hard constraint for this part: a modest sensor-fusion stack, a small UART buffer, and maybe one or two ADC result arrays fit. The 8 KB Flash holds a lean firmware image without a bootloader staging area — plan for factory-programmed or one-time field updates via the internal Flash routines. The 40-VFQFN exposed-pad package (6x6 mm body) needs a thermal via stitch under the pad if continuous dissipation approaches 400 mA.

No last-time-buy notice or end-of-life schedule has been published.

Package and footprint — 40-VQFN with exposed pad

The 32 available I/O lines run through the 40 pins; the remaining eight pins cover supply, ground, and the internal oscillator.

Frequently asked questions

What is the closest functional alternative to MSP430F2232IRHAT?

The TI F280041PZQR is a 32-bit C2000 C28x MCU running at 100 MHz with 12-bit ADC and CAN interface, but it is a different architecture (32-bit vs 16-bit), higher performance tier, and automotive-qualified (-40 to 125°C). It is not a pin-compatible or software-compatible substitute for the MSP430F2232IRHAT. For a direct MSP430 alternative within the same family, consider the MSP430F2232 (the base part number without the IRHA suffix — same die, different packaging options).
