Product details

2 KB Flash and 128 B RAM — sizing the firmware footprint

The 2 KB Flash (2K x 8) is the program store; with 128 bytes of RAM, this part targets simple control loops, state machines, and communication protocol handling where the code fits in a few hundred instructions. The 16-bit core processes 16 MHz clock cycles efficiently for bit-banged interfaces or PWM generation. The RAM is tight — expect to use register-based variables and lean data structures. For designs that need more headroom, the MSP430G2 family offers pin-compatible options with larger Flash and RAM, but the 2 KB / 128 B combination keeps the die small and the cost low for high-volume automotive modules.

Frequently asked questions

Is MSP430G2211IRSARQ1 automotive qualified?

Yes, the MSP430G2211IRSARQ1 is part of the Automotive, AEC-Q100 series, meaning it has passed the AEC-Q100 stress tests for automotive-grade integrated circuits.

What is the closest pin-compatible alternative to MSP430G2211IRSARQ1 in this component family?

The MSP430G2 family includes several pin-compatible devices with varying Flash and RAM sizes. A direct step-up with more memory is the MSP430G2231, which offers 2 KB Flash and 128 B RAM in the same 16-QFN package, but with a different peripheral set. For a like-for-like replacement, compare the base product number MSP430G2211 variants — the 'IRSAR' suffix denotes the 16-QFN tape-and-reel option.
