Product details
Overview
MSP430F5232IRGZR from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller with 64 KB flash, 4 KB RAM, four 16-bit timers (TA0/TA1/TA2/TB0), two USCI modules (UART/IrDA/SPI/I²C), RTC, comparator, and hardware multiplier - designed for battery-powered sensor nodes and data loggers operating from 1.8 V to 3.6 V.
For engineers reviewing the MSP430F5232IRGZR datasheet, MSP430F5232IRGZR pinout, MSP430F5232IRGZR application, or MSP430F5232IRGZR equivalent, key selection criteria include LPM4.5 shutdown current (0.18 µA), 3.5 µs wake-up time from LPM3, 48-pin VQFN package (7 mm × 7 mm), and absence of integrated ADC - distinguishing it from F524x series variants.
Technical Context
The MSP430F5232IRGZR implements a unified clock system with FLL stabilization, dual crystal support (XT1 for 32-kHz RTC, XT2 up to 32 MHz), and three internal sources (VLO, REFO, DCO). Its power management includes an integrated LDO with programmable core voltage and brownout detection.
It features three-channel DMA, port mapping control for peripheral function remapping, and full RAM retention in LPM3/LPM4 modes. The device belongs to the MSP430F523x series, which omits the 10-bit ADC present in F524x counterparts while retaining identical timer, USCI, RTC, and comparator configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | 16-bit RISC CPU with constant generators and 25-MHz max system clock - enables efficient C code execution and low-cycle-count real-time control. |
| Memory | 64 KB flash / 4 KB RAM - sufficient for firmware with protocol stacks and buffered sensor data in compact embedded systems. |
| Low-Power Modes | LPM4.5 draws 0.18 µA at 3.0 V - extends shelf life and operational runtime in energy-harvesting or coin-cell-powered devices. |
| Wake-up Time | 3.5 µs from LPM3 - supports rapid response to external interrupts without sacrificing sleep efficiency. |
| Timers | TA0 (5 CC), TA1 (3 CC), TA2 (3 CC), TB0 (7 CC) - enables concurrent PWM generation, input capture, and RTC/calendar functions. |
| Communication | USCI_A0/A1 (UART/IrDA/SPI), USCI_B0/B1 (I²C/SPI) - provides dual asynchronous and synchronous interfaces for sensor fusion and host connectivity. |
| Supply Range | 1.8 V to 3.6 V - compatible with single Li-ion, two alkaline, or regulated 3.3-V rails without external level shifting. |
Pinout & Package

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 |
|---|---|---|---|
| MSP430F5234IRGZR | Same package and peripherals, but with 128 KB flash and 4 KB RAM - no ADC. | Preferred when larger firmware image size is required (e.g., OTA update capability or complex protocol stacks). | Select MSP430F5234IRGZR if firmware exceeds 64 KB or future scalability is needed; otherwise, MSP430F5232IRGZR offers optimal cost/performance balance. |
| MSP430F5242IRGZR | Same package and memory size, but includes 10-bit ADC with 8 external channels - adds 2.5 mW active power overhead. | Suitable when direct analog sensing (e.g., thermistor, potentiometer) is required without external ADC. | Choose MSP430F5242IRGZR only if on-chip ADC functionality is mandatory; MSP430F5232IRGZR avoids ADC-related noise coupling in precision analog systems. |
Compared with MSP430F5234IRGZR, the MSP430F5232IRGZR trades flash capacity for lower unit cost and identical low-power behavior; versus MSP430F5242IRGZR, it removes ADC circuitry to reduce leakage, improve EMI immunity, and simplify analog partitioning - making it ideal for digital-sensor-only or externally conditioned analog systems.

FAQ
What is the maximum system clock frequency supported by the MSP430F5232IRGZR?
The MSP430F5232IRGZR supports a maximum system clock frequency of 25 MHz. This is achieved using the FLL-controlled DCO with XT2 crystal input (up to 32 MHz) or internal reference sources. The 25-MHz rating reflects guaranteed timing performance across voltage and temperature ranges per TI's SLAS897C specification.
Does the MSP430F5232IRGZR include an analog-to-digital converter (ADC)?
No, the MSP430F5232IRGZR does not include an ADC. It belongs to the MSP430F523x series, which explicitly excludes the 10-bit ADC present in the F524x series. This omission reduces power consumption and die area, making MSP430F5232IRGZR suitable for digital-sensor or externally conditioned analog applications.
What package type and dimensions does the MSP430F5232IRGZR use?
The MSP430F5232IRGZR uses a 48-pin VQFN package (RGZR suffix), measuring 7 mm × 7 mm with 0.5-mm lead pitch and an exposed thermal pad. This package is specified in TI's SLAS897C datasheet and supports automated assembly and efficient thermal transfer in compact designs.
How many universal serial communication interfaces (USCIs) are available on the MSP430F5232IRGZR?
The MSP430F5232IRGZR includes two USCI modules: USCI_A0 and USCI_A1 support UART, IrDA, and SPI; USCI_B0 and USCI_B1 support I²C and SPI. Each USCI is independently configurable, enabling concurrent UART + I²C or dual SPI buses without resource conflict.
What is the typical current consumption of the MSP430F5232IRGZR in standby (LPM3) mode?
In standby mode (LPM3) with RTC, watchdog, and supply supervisor active and full RAM retention, the MSP430F5232IRGZR consumes 1.9 µA at 2.2 V and 2.1 µA at 3.0 V (typical). These values are measured with 32-kHz crystal enabled and are specified in Section 8.5 of the SLAS897C datasheet.
