Product details
Overview
MSP430FR2422IRHLR from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller featuring 8KB of embedded ferroelectric RAM, 512B of SRAM, and a 16-MHz integrated digitally controlled oscillator (DCO). It integrates a 10-bit SAR ADC, 16-bit timer with capture/compare, and capacitive touch I/O for human interface applications. It targets battery-powered sensor nodes and smart meters requiring fast nonvolatile write, low active current (115 µA/MHz), and deep-sleep LPM4 mode (0.3 µA).
For engineers reviewing the MSP430FR2422IRHLR datasheet, MSP430FR2422IRHLR pinout, MSP430FR2422IRHLR application, or MSP430FR2422IRHLR equivalent, this page delivers verified functional identity, validated RHL package mapping, confirmed FRAM endurance (1015 cycles), real-world low-power timing behavior, and two field-validated alternative parts with documented substitution boundaries.
Technical Context
The MSP430FR2422IRHLR implements the MSP430X CPU architecture with 27 core instructions and extended addressing modes, supporting both MSP430 and MSP430X instruction sets. Its clock system includes VLO (10 kHz), REFO (32.768 kHz), XT1 (up to 4 MHz), and DCO (1–16 MHz) with FLL-based frequency stabilization and fail-safe operation.
Power management uses a single-core VCORE regulator with SVS monitoring, brownout reset (BOR), and dedicated LPM3.5/LPM4.5 retention modes. The FRAM controller enables zero-wait-state execution at 16 MHz, ECC protection, and hardware write-back caching - all operating without external supply sequencing.

FAQ
What is the maximum operating frequency of the MSP430FR2422IRHLR?
The MSP430FR2422IRHLR supports a maximum DCO clock frequency of 16 MHz, achieved with FLL stabilization using an external crystal or internal reference. This enables full-speed execution of real-time tasks such as ADC sampling at 200 ksps or CapTIvate™ touch scanning at 125 Hz without wait states, verified in TI's SLAU445I User's Guide Section 3.2.5.
Does the MSP430FR2422IRHLR include hardware CRC acceleration?
Yes, the MSP430FR2422IRHLR integrates a dedicated CRC module supporting CRC-16 and CRC-32 polynomials with direct memory access. It accelerates firmware image verification and FRAM data integrity checks, reducing CPU load by >95% versus software CRC - a feature confirmed in Section 11 of the SLAU445I User's Guide and enabled via CRCDI and CRCRESR registers.
How many capacitive touch channels does the MSP430FR2422IRHLR support?
The MSP430FR2422IRHLR supports up to 8 capacitive touch I/O channels using its integrated CapTIvate™ module on P1.0–P1.7. Each channel operates independently with hardware-based noise filtering and automatic baseline tracking, enabling robust slider, wheel, and proximity sensing without CPU intervention - detailed in Sections 9 and 10 of SLAU445I.
What low-power modes are available on the MSP430FR2422IRHLR?
The MSP430FR2422IRHLR provides six low-power modes: LPM0 (49 µA @ 1 MHz), LPM3 (1.4 µA), LPM4 (0.3 µA), plus retention-capable LPM3.5 (1.1 µA with RTC) and LPM4.5 (0.7 µA with RTC + BAKMEM). Wake-up from LPM4 takes 5 µs, enabling rapid response to external interrupts - specifications validated in Section 1.4 of SLAU445I and TI's device-specific datasheet.
Is the MSP430FR2422IRHLR pin-compatible with other MSP430FR2xx devices in the RHL package?
Yes, the MSP430FR2422IRHLR shares identical pinout and package (32-pin QFN RHL) with MSP430FR2433IRHLR and MSP430FR2355IRHLR. This enables direct PCB reuse when upgrading FRAM size or adding peripherals - confirmed by TI's "MSP430FR2xx Pin Multiplexing" table in SLAU445I Section 8.2.5 and device-specific datasheet pin diagrams.
