Product details

Automotive-grade 16-bit MCU for sensor and body-control nodes

This part is production-released for automotive Tier-1 and OEM programs, with the qualification data package available from TI.

Memory ceiling and peripheral fit

With 1 KB Flash and 128 bytes of RAM, this MCU is sized for single-purpose control loops — a LIN slave node, a seat-position sensor, or a window-lift controller — not for complex protocol stacks or data logging.

For dual-sourcing resilience, the non-Q1 MSP430G2111IPW is pin-compatible but lacks the automotive qualification — qualify both if your BOM splits across automotive and industrial builds.

Frequently asked questions

Is MSP430G2111IPW4Q1 AEC-Q100 qualified?

This is the key difference from the standard MSP430G2111IPW.

What is the RAM size of MSP430G2111IPW4Q1?

The RAM size is 128 x 8 (128 bytes). Combined with 1 KB of Flash, this sets the firmware and data-handling ceiling for the application.

Can MSP430G2111IPW4Q1 be used as a drop-in replacement for MSP430G2111IPW?

Yes, it is pin-compatible and footprint-identical in the 14-TSSOP package, with the same supply range and peripheral set. The only difference is the AEC-Q100 automotive qualification on the Q1 variant.

What is the maximum clock speed of MSP430G2111IPW4Q1?

The maximum clock speed is 16 MHz, driven by the internal oscillator or an external clock source.
