512 KB Flash and 66 KB RAM — what that means for firmware and data
The 512 KB Flash is sized for a substantial firmware image — enough for a Modbus RTU stack, PID loops, and a local data logger without external memory. The 66 KB RAM gives headroom for large frame buffers or multi-channel ADC result arrays. If your BOM was built around this density tier, a drop-in replacement needs to match both Flash and RAM, not just the core speed.
20 MHz core speed — timing budget for control loops
20 MHz core, typical for MSP430F5xx family. Adequate for mid-range control and data acquisition tasks.
Package and mounting — 113-VFBGA BGA
The 113-VFBGA (Microstar Junior 7x7 mm) is a fine-pitch BGA — reflow soldering and X-ray inspection are required. No hand-soldering. Store the reels dry; the package is moisture-sensitive and the Tape & Reel delivery means the parts arrive ready for pick-and-place. Verify your reflow profile against the BGA's recommended thermal curve before committing a board run.
