Product details

The MSP430FR2422IRHLR: 16-bit FRAM MCU, 16 MHz core, 7.5 KB FRAM, 2 KB RAM, 15 I/O, 8x10b ADC, I²C/SPI/UART/IrDA. Operates from 2 V to 3.6 V, -40°C to 85°C, 20-VFQFN exposed pad.

FRAM memory — what it changes for the firmware strategy

16 MHz core — enough for sensor polling and control loops

16 MHz core handles sensor read-and-respond cycles, PID loops, and serial protocol framing. Not a DSP-class part.

Active product status from Texas Instruments. No last-time-buy notice or obsolescence date. Sourced and quoted to order through independent distribution.

Frequently asked questions

What is the exact package and footprint for MSP430FR2422IRHLR?

It comes in a 20-VFQFN with exposed pad, supplier device package 20-VQFN measuring 3.5x4.5 mm. The pad is internally tied to VSS and should be soldered to a thermal land on the PCB.

What are the alternatives or replacements for MSP430FR2422IRHLR?

No official pin-compatible replacement or second-source alternate is cited in the available records. For a drop-in within the same MSP430 FRAM family, compare the MSP430FR2422 base part's density and I/O count — higher-density siblings share the same footprint.

What is MSP430FR2422IRHLR's listed speed?

The core runs at 16 MHz, driven by an internal oscillator — no external crystal required for basic operation.
