Product details
Overview
MSP430F5232IRGZT from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller with 64 KB flash, 4 KB RAM, dual USCI modules (UART/IrDA/SPI/I²C), three 16-bit timers (TA0/TA1/TA2), Timer_B with seven capture/compare registers, RTC, hardware multiplier, and comparator-designed for battery-powered sensor nodes and data loggers operating at 1.8–3.6 V.
For engineers reviewing the MSP430F5232IRGZT datasheet, MSP430F5232IRGZT pinout, MSP430F5232IRGZT application, or MSP430F5232IRGZT equivalent, this page delivers verified specifications, package-confirmed pin functions, low-power mode timing, peripheral register mapping, and direct alternative part comparisons for embedded firmware and PCB design validation.
Technical Context
The MSP430F5232IRGZT implements a unified clock system with FLL stabilization, programmable LDO core regulation, and four low-power modes (LPM0–LPM4.5). Its CPUXV2 core supports 25-MHz operation with constant generators for optimized code density.
It integrates two USCI modules: USCI_A0/USCI_A1 support UART with auto-baud detection and IrDA; USCI_B0/USCI_B1 support I²C and SPI. Unlike the F524x series, it omits the 10-bit ADC but retains all other peripherals-including COMP_B (6-channel), RTC_A, and DMA (3-channel).

FAQ
What is the maximum operating frequency of the MSP430F5232IRGZT?
The MSP430F5232IRGZT supports a maximum system clock frequency of 25 MHz, achieved via its digitally controlled oscillator (DCO) with FLL stabilization. This frequency is confirmed in the device's functional block diagram and Section 8.19 (DCO Frequency) of the SLAS897C datasheet, where tCYCLE = 40 ns specifies the minimum instruction cycle time.
Does the MSP430F5232IRGZT include an analog-to-digital converter (ADC)?
No, the MSP430F5232IRGZT does not include an ADC. As explicitly stated in the family description and Device Comparison table (Section 6.1), the MSP430F523x series omits the ADC10_A module present in the F524x series. The MSP430F5232IRGZT retains COMP_B (6-channel comparator), timers, USCI, RTC, and DMA-but requires external ADC for analog signal acquisition.
What package type and pin count does the MSP430F5232IRGZT use?
The MSP430F5232IRGZT uses a 48-pin VQFN package (RGZ) with 7 mm × 7 mm body size and an exposed thermal pad. This is confirmed in the Device Information table and Figure 7-4 (pinout diagram) of the SLAS897C datasheet, which specifically labels "MSP430F5232IRGZ" and "MSP430F5234IRGZ" for the RGZ footprint.
How many universal serial communication interfaces (USCI) does the MSP430F5232IRGZT have?
The MSP430F5232IRGZT has two USCI modules: USCI_A0 and USCI_A1 (each supporting UART, IrDA, and SPI), and USCI_B0 and USCI_B1 (each supporting I²C and SPI). This configuration is documented in Section 1 Features and validated in the functional block diagram (Figure 4-4) and Device Comparison table (Table 6-1).
What is the standby current consumption of the MSP430F5232IRGZT in LPM3 mode?
The MSP430F5232IRGZT consumes 1.9 µA at 2.2 V and 2.1 µA at 3.0 V in LPM3 mode with RTC, watchdog, and supply supervisor active and full RAM retention. These values are specified in the "Ultra-low power consumption" section under Standby Mode (LPM3) and confirmed in Section 8.5 (Low-Power Mode Supply Currents) of the SLAS897C datasheet.
