Product details
Overview
MSP430F5234IRGZR from Texas Instruments is a 16-bit ultra-low-power mixed-signal microcontroller in the MSP430F523x series, designed for battery-operated sensor and data-logging applications. It features 128 KB flash, 8 KB RAM, four 16-bit timers (TA0/TA1/TA2/TB0), two USCI modules (UART/IrDA/SPI/I²C), RTC, hardware multiplier, and 3-channel DMA - all operating down to 1.8 V with standby current as low as 1.9 µA.
For engineers reviewing the MSP430F5234IRGZR datasheet, MSP430F5234IRGZR pinout, MSP430F5234IRGZR application, or MSP430F5234IRGZR equivalent, key selection criteria include its RGZ package (48-pin VQFN), absence of integrated ADC (distinguishing it from F524x variants), 37 GPIOs, and compatibility with TI's MSP430 development ecosystem including CCS and MSP-FET.
Technical Context
The MSP430F5234IRGZR implements a 16-bit RISC CPUXV2 core with constant generators and unified clock system featuring FLL stabilization, VLO, REFO, XT1 (32 kHz), and XT2 (up to 32 MHz). Its power management includes an integrated LDO with programmable core voltage and supply supervision with brownout detection.
Peripherals are mapped via port mapping control (P4) and support flexible I/O configuration. The device lacks ADC10_A but retains COMP_B (6-channel comparator), full RTC_A functionality, and dual USCI modules - one supporting UART/IrDA/SPI (USCI_A0), the other supporting I²C/SPI (USCI_B0).

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 |
|---|---|---|---|
| MSP430F5232IRGZR | 64 KB flash (vs. 128 KB), same RAM, timers, USCI, and no ADC | Suitable for simpler firmware with smaller code footprint; lower cost where memory headroom is not required | Select when application firmware fits in ≤64 KB and BOM cost optimization is prioritized |
| MSP430F5244IRGZ | Includes 8-channel external-input ADC10_A (10-bit, 200 ksps); same package and memory size | Required for direct analog sensor interfacing (e.g., thermistor, potentiometer) without external ADC | Choose when analog signal acquisition is needed - MSP430F5234IRGZR requires external ADC or digital sensors |
Compared with MSP430F5232IRGZR, the MSP430F5234IRGZR provides double flash capacity for feature-rich firmware; compared with MSP430F5244IRGZ, it trades ADC integration for lower power in purely digital sensor systems.

FAQ
Does the MSP430F5234IRGZR include an analog-to-digital converter (ADC)?
No, the MSP430F5234IRGZR does not integrate an ADC. It belongs to the MSP430F523x series, which omits the ADC10_A module present in the F524x series. Designers must use external ADCs or digital-output sensors. This omission reduces active and standby current, making MSP430F5234IRGZR optimal for purely digital sensor aggregation or protocol translation tasks.
What is the maximum system clock frequency supported by the MSP430F5234IRGZR?
The MSP430F5234IRGZR supports a maximum system clock frequency of 25 MHz. This is achieved using the FLL-controlled DCO with XT2 (high-frequency crystal up to 32 MHz) or internal reference sources. The 25-MHz limit ensures timing compliance across all peripherals, including USCI baud-rate generation and timer capture/compare accuracy.
Which development tools are compatible with the MSP430F5234IRGZR?
The MSP430F5234IRGZR is fully supported by Texas Instruments' MSP430Ware software library, Code Composer Studio (CCS) IDE, and the MSP-FET debugger. Its Spy-Bi-Wire interface (TEST/SBWTCK and RST/NMI pins) enables programming and debugging using only two wires - no JTAG header required - simplifying prototype and production test setups.
How many general-purpose I/O pins does the MSP430F5234IRGZR provide?
The MSP430F5234IRGZR provides 37 general-purpose I/O pins in its 48-pin RGZ package. These are distributed across Ports P1–P6 and PJ, with configurable pull-up/down, slew rate, and drive strength. Pin functions are multiplexed via port mapping control (P4), enabling flexible peripheral assignment without PCB redesign.
What is the standby (LPM3) current consumption of the MSP430F5234IRGZR?
The standby (LPM3) current consumption of the MSP430F5234IRGZR is 1.9 µA at 2.2 V and 2.1 µA at 3.0 V (typical), with RTC, watchdog, and supply supervisor active and full RAM retention. This ultra-low value is achieved through integrated LDO regulation, optimized leakage control, and selective peripheral gating - critical for multi-year battery operation in remote sensing applications.
