Product details

FRAM-based 16-bit MCU for low-power instrumentation

Rated for -40°C to 85°C and 1.8 V to 3.6 V supply, it covers industrial and outdoor telecom environments without external level shifting on the core rail.

16 MHz CPU clock. Internal oscillator eliminates external crystal.

This part carries an EOL-hot lifecycle status. While TI lists the product status as Active, the EOL-hot flag signals that a last-time-buy window is open or imminent. Buyers should secure their lifetime requirements now and evaluate the pin-compatible MSP430FR5949 family siblings for long-term production continuity.

Frequently asked questions

What is MSP430FR5949IRHAT's listed speed (16MHz) on this component line?

The CPU clock is rated at 16 MHz, driven by an internal oscillator. That sets the maximum instruction throughput for the MSP430 CPUXV2 core.
