Product details
Overview
MSP430FR2422IPW16R from Texas Instruments is a 16-bit RISC ultra-low-power microcontroller featuring 7.25 KB FRAM program memory, 256 B information FRAM, 2 KB RAM, and an 8-channel 10-bit ADC operating at up to 200 ksps - deployed in battery-powered sensing applications such as portable medical devices and industrial sensor nodes.
For engineers reviewing the MSP430FR2422IPW16R datasheet, MSP430FR2422IPW16R pinout, MSP430FR2422IPW16R application, or MSP430FR2422IPW16R equivalent, key selection criteria include its 16-pin TSSOP (PW) package, 1.8–3.6 V supply range, LPM3.5 RTC operation at 710 nA, FRAM endurance of 1015 write cycles, and dual eUSCI modules supporting UART/I²C/SPI with pin remap.
Technical Context
The MSP430FR2422IPW16R integrates a 16-MHz digitally controlled oscillator (DCO) with FLL, ±1% accuracy at room temperature, and supports multiple clock sources including internal REFO (32 kHz), VLO (10 kHz), MODOSC, and external LFXT crystal. Its clock system enables programmable MCLK prescaling (1–128) and SMCLK derivation with 1/2/4/8 division.
It features two Timer_A3 peripherals (each with three capture/compare registers), a dedicated 16-bit RTC counter, CRC16 engine, and intelligent I/O with 11 GPIOs on the PW package - all managed under a unified power management module supporting six low-power modes, including LPM4.5 (36 nA shutdown).

FAQ
What is the maximum operating frequency of the MSP430FR2422IPW16R?
The MSP430FR2422IPW16R supports a maximum CPU clock frequency of 16 MHz, achieved using the on-chip digitally controlled oscillator (DCO) with frequency-locked loop (FLL). This frequency is maintained within ±1% accuracy at room temperature using the internal reference, enabling deterministic real-time execution without external crystal dependency.
How many ADC input channels does the MSP430FR2422IPW16R support in its TSSOP-16 package?
The MSP430FR2422IPW16R supports five analog input channels (A0–A4) in the TSSOP-16 package, mapped to pins P1.0, P1.1, P1.2, P1.3, and P2.2. Unlike the 20-pin VQFN variant, the 16-pin version omits A5–A7 due to pin count constraints, but retains the full 10-bit resolution and 200 ksps sampling capability.
Does the MSP430FR2422IPW16R include hardware encryption or secure boot features?
No, the MSP430FR2422IPW16R does not include hardware encryption accelerators, secure boot, or tamper-detection circuitry. It relies on software-based security measures and external secure elements for cryptographic operations. Its design prioritizes ultra-low power and cost efficiency over hardware security - making it suitable for non-safety-critical sensing applications.
What debug interface is supported by the MSP430FR2422IPW16R?
The MSP430FR2422IPW16R supports Spy-Bi-Wire (SBW) debug interface via dedicated pins SBWTCK (Pin 3) and SBWTDIO (Pin 4), requiring only two signals for full programming and real-time debugging. It does not support full 4-wire JTAG; SBW is TI's optimized low-pin-count alternative compatible with MSP-FET and LaunchPad debug probes.
Can the MSP430FR2422IPW16R operate from a single 1.8-V supply without performance degradation?
Yes, the MSP430FR2422IPW16R is fully specified to operate down to 1.8 V, with all peripherals-including the 16-MHz DCO, 10-bit ADC, and eUSCI modules-functional across the entire 1.8–3.6 V range. At 1.8 V, the maximum achievable DCO frequency is reduced per datasheet curves, but 8-MHz operation remains stable and sufficient for most sensor polling and communication tasks.
