2 KB Flash and 256 B RAM — sizing the control task
The MSP430G2203IRHB32R is a 16-bit ultra-low-power microcontroller from TI's MSP430G2xx family, built around the MSP430 CPU16 core.
32-VQFN package — rework and layout notes
The 32-VFQFN with exposed pad (5x5 mm body) is a compact, low-profile package. The 24 I/O lines are all accessible on the peripheral pads.
For dual-sourcing resilience, the MSP430G2xx family includes several pin-compatible Flash-density variants (e.g., 1 KB to 8 KB options) that share the same 32-VQFN footprint, though the exact memory and peripheral mix should be verified against the target application's code size.
