Product details
Overview
MSP430FR5734IRGER from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller featuring 8KB FRAM nonvolatile memory, 1KB SRAM, and a 24-MHz CPU. It integrates a 10-bit ADC with 6 external channels, a 16-channel analog comparator, three eUSCI modules (two UART/SPI-capable, one I²C/SPI-capable), and five 16-bit timers. It targets battery-powered sensor nodes in industrial monitoring systems.
For engineers reviewing the MSP430FR5734IRGER datasheet, MSP430FR5734IRGER pinout, MSP430FR5734IRGER application, or MSP430FR5734IRGER equivalent, key selection criteria include FRAM endurance (10¹⁵ write cycles), LPM3.5 RTC current (1.5 µA), 24-pin VQFN package footprint, and compatibility with TI's MSP-FET430U40A debug interface.
Technical Context
The MSP430FR5734IRGER implements the MSP430xV2 CPU core with unified FRAM memory architecture enabling simultaneous code execution and data writes without wait states. Its power management includes seven low-power modes, with LPM4.5 consuming only 0.32 µA and LPM3.5 (RTC active with crystal) drawing 1.5 µA.
Peripherals are tightly coupled to the 3-channel DMA and hardware multiplier (MPY32). The ADC10_B supports 200 ksps sampling at 100 µA, while the comparator_D provides programmable hysteresis and internal voltage reference generation for threshold detection in sensor signal conditioning.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| FRAM Capacity | 8 KB nonvolatile memory with 10¹⁵ write cycle endurance and 125 ns/word write speed - enables frequent logging without wear-out. |
| CPU Speed | Up to 24 MHz - supports real-time control loops and protocol stack processing in compact firmware. |
| ADC Resolution | 10-bit with 6 external input channels - sufficient for precision temperature, pressure, or voltage sensing in field-deployed nodes. |

| Package | VQFN-24 (4 mm × 4 mm, 0.5 mm pitch) - surface-mount compatible with high-density PCB layouts and automated assembly. |
| Supply Voltage | 2.0 V to 3.6 V - operates directly from single-cell Li-ion or two-cell alkaline batteries without regulation overhead. |
| eUSCI Peripherals | eUSCI_A0/A1 (UART/IrDA/SPI), eUSCI_B0 (I²C/SPI) - supports dual serial interfaces for sensor fusion (e.g., I²C temp/humidity + UART telemetry). |
Pinout & Package
VQFN-24 package (RGE) with exposed thermal pad connected to DVSS. Pin count and layout optimized for compact sensor node designs requiring minimal board area and robust thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| Real-Time Clock (RTC_B) | Calendar mode with alarm interrupt - enables autonomous wake-up every hour/day for periodic sensor polling without host intervention. |
| Comparator_D with Hysteresis | Programmable hysteresis on all 10 comparator inputs - prevents chatter during slow-moving analog signals (e.g., thermistor ramps or light-level transitions). |
| Three eUSCI Modules | Dual UART/SPI (eUSCI_A0/A1) + I²C/SPI (eUSCI_B0) - supports concurrent communication with UART-based radio modules and I²C sensors on shared bus. |
Applications
| Smart Meter Sensor Interface | Wireless Environmental Node |
|---|---|
Use Scenario: Reads voltage/current transformers and temperature sensors in residential electricity meters, storing time-stamped samples in FRAM. IC Role / Device Role / Timing Role: Primary system controller executing metrology algorithms, managing RTC-triggered sampling, and buffering data before RF transmission. Use Value: 8 KB FRAM retains 10+ days of 1-second interval readings without wear degradation; LPM3.5 draws only 1.5 µA during idle periods between samples. | Use Scenario: Monitors indoor air quality (CO₂, humidity, VOC) in HVAC systems using I²C sensors and transmits alerts via UART-connected LoRa module. IC Role / Device Role / Timing Role: Sensor hub aggregating multi-sensor data, applying digital filtering, and scheduling low-duty-cycle RF transmissions. Use Value: Hardware multiplier (MPY32) accelerates CO₂ compensation math; eUSCI_B0 handles I²C sensor reads while eUSCI_A1 manages UART telemetry - no software arbitration needed. |
| Industrial Asset Monitor | Portable Data Logger |
Use Scenario: Mounted on motors or pumps to log vibration (via analog accelerometer), temperature, and runtime hours for predictive maintenance. IC Role / Device Role / Timing Role: Edge analytics node performing FFT preprocessing on ADC samples and triggering alerts based on threshold crossings. Use Value: Comparator_D with programmable hysteresis detects rapid temperature excursions; FRAM endures 10¹⁵ writes - outlasting the equipment it monitors. | Use Scenario: Handheld device recording environmental parameters (light, noise, humidity) during field surveys, with USB-like data export via UART bootloader. IC Role / Device Role / Timing Role: Standalone data acquisition unit with integrated BSL enabling field firmware updates without dedicated programmers. Use Value: Hardware UART bootloader (BSL) allows reprogramming over existing UART interface - eliminates need for SWD probes in deployed units. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430FR5732IRGER | Same 8KB FRAM, 1KB SRAM, and VQFN-24 package but lacks ADC10_B - only 6-channel comparator_D and no analog-to-digital conversion capability. | Restricted to purely digital threshold detection (e.g., switch monitoring), not suitable for analog sensor digitization. | Select when analog sensing is unnecessary and lowest BOM cost is prioritized over ADC flexibility. |
| MSP430FR5734IPW | Identical core specs (8KB FRAM, 24-MHz CPU, ADC10_B w/6 ch.) but in 28-pin TSSOP (PW) package - larger footprint, through-hole or surface-mount compatible. | Better suited for prototyping or low-volume production where hand-soldering or socketing is required. | Select for lab evaluation or legacy PCB compatibility where VQFN reflow is unavailable. |
Compared with MSP430FR5732IRGER, the MSP430FR5734IRGER adds essential ADC functionality for analog sensor interfacing; compared with MSP430FR5734IPW, it offers 30% smaller board area and improved thermal dissipation in space-constrained deployments.

FAQ
What is the maximum operating frequency of the MSP430FR5734IRGER?
The MSP430FR5734IRGER supports a maximum system clock frequency of 24 MHz, achieved via its factory-trimmed DCO oscillator or external HFXT crystal. This speed enables real-time execution of control algorithms and protocol stacks while maintaining ultra-low-power efficiency in active mode (81.4 µA/MHz typical). The MSP430FR5734IRGER's architecture sustains this performance across its full 2.0–3.6 V supply range.
Does the MSP430FR5734IRGER include hardware support for cryptographic operations?
No, the MSP430FR5734IRGER does not integrate dedicated cryptographic accelerators or secure boot features. It relies on software-based implementations for encryption or authentication tasks. For applications requiring hardware security, designers should consider TI's MSP430FR59xx series or companion secure elements. The MSP430FR5734IRGER focuses on ultra-low-power analog integration and FRAM reliability rather than cryptographic acceleration.
Can the MSP430FR5734IRGER operate from a single 3.0-V lithium coin cell?
Yes, the MSP430FR5734IRGER operates across 2.0 V to 3.6 V, making it fully compatible with standard 3.0-V CR2032 coin cells. In LPM4.5 shutdown mode, it draws only 0.32 µA - enabling multi-year operation on a single cell when paired with duty-cycled sensing. Its integrated LDO ensures stable core voltage even as battery voltage declines, and the MSP430FR5734IRGER's SVS circuit provides brownout reset at programmable thresholds.
How many analog input channels does the ADC10_B module support on the MSP430FR5734IRGER?
The ADC10_B module on the MSP430FR5734IRGER supports six external analog input channels (A0–A5) plus two internal references (VeREF+ and VeREF−), as confirmed in the device comparison table and signal descriptions. This configuration matches the RGE-package variant and is validated for operation up to 200 ksps with 100 µA typical current consumption - sufficient for multi-sensor data acquisition in compact nodes.
Is the MSP430FR5734IRGER pin-compatible with other devices in the MSP430FR57xx family?
The MSP430FR5734IRGER shares the same 24-pin VQFN (RGE) package footprint and pinout with MSP430FR5730IRGER, MSP430FR5732IRGER, MSP430FR5736IRGER, and MSP430FR5738IRGER - enabling direct substitution within the RGE package group. However, functional differences exist (e.g., ADC channel count, timer configurations), so firmware and peripheral initialization must be verified per device. The MSP430FR5734IRGER is not pin-compatible with RHA or DA package variants.
