Product details

16 MHz, 4 KB Flash, 256 B RAM — sizing the MSP430G2312IRSA16T for your BOM

Memory budget — the binding constraint

With 4 KB of Flash and 256 bytes of RAM, the firmware engineer needs to budget tightly. The 4 KB program space fits a modest state machine, a few lookup tables, and the MSP430's peripheral driver library — but leave room for the bootloader and calibration constants. The 256-byte RAM ceiling means stack depth and global variables must be counted, not guessed; a deep call tree or a large DMA buffer will overflow silently. The DMA and PWM peripherals are present, but using them together with a serial protocol may exhaust the RAM allocation.

Package and footprint — 16-QFN with exposed pad

The pad is not just a thermal path — it is also the electrical ground connection for the die. No through-hole variant exists.

Frequently asked questions

What is the closest pin-compatible alternative to MSP430G2312IRSA16T?

Within the MSP430G2xx family, the MSP430G2452 (same 16-QFN footprint, 8 KB Flash, 512 B RAM) is a direct drop-in upgrade if more memory is needed. The base product number MSP430G2312 shares the same pinout across density variants, so a BOM swap requires no PCB change.
