Product details

4 KB Flash and 256-byte RAM — sizing the firmware budget

The MSP430G2302IRSA16R: The 4 KB Flash (4K x 8) is the hard ceiling for application code and constant data. That is enough for a small state machine, a few sensor reads, and a communication protocol handler, but it rules out a full RTOS or a TCP/IP stack. The 256 x 8 RAM handles a modest call stack and a handful of variables — watch the linker map if you are adding interrupt service routines with deep nesting. For a firmware engineer, the internal oscillator and brown-out reset (BOR) reduce external component count, but the 16 MHz PLL requires setting flash wait states correctly at speed or the first branch out of reset hard-faults.

Frequently asked questions

What is the difference between MSP430G2302IRSA16R and MSP430G2402?

The MSP430G2402 is a higher-density sibling in the same MSP430G2xx family. It doubles the Flash program memory to 8 KB and the RAM to 512 bytes, while keeping the same 16 MHz core, 16-QFN package, pinout, and peripheral set. If your firmware fits in 4 KB, the G2302 is the cost-optimized choice; if you need the extra code space, the G2402 is the drop-in upgrade without a board respin.

Are MSP430G2302 and MSP430G2302IRSA16R the same?

MSP430G2302 is the base product number for the entire family variant. The base number alone does not uniquely identify the package or reel option — always order the full code for BOM accuracy.
