Rated -40°C to 85°C, this MCU fits industrial enclosures and factory-floor controllers. The 87-VFBGA (6×6 mm) package saves board area but demands fine-pitch PCB routing. The supplier device package is the same footprint; the suffix IZVWR vs IRGCR is the reel-and-tape variant, not a silicon change.
The core runs at 16 MHz — the MSP430 CPUXV2 pipeline executes most instructions in one or two cycles, so effective throughput is competitive with 32-bit cores at similar clock rates for control-loop code.
