Product details
Overview
MSP430F5304IRGZR from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller with 8 KB flash, 6 KB RAM, four 16-bit timers (TA0/TA1/TA2/TB0), a 10-bit 200 kSPS ADC with window comparator, one USCI (UART/IrDA/SPI/I²C), RTC module, hardware multiplier, and 31 GPIOs in a 48-pin VQFN package. It operates from 1.8 V to 3.6 V and targets battery-powered sensor systems and digital timers.
For engineers reviewing the MSP430F5304IRGZR datasheet, MSP430F5304IRGZR pinout, MSP430F5304IRGZR application, or MSP430F5304IRGZR equivalent, key selection criteria include its single-USCI configuration, 31 I/O count, 8 KB flash size, LPM4.5 shutdown current of 0.18 µA, and VQFN-48 thermal-pad package compatibility with space-constrained embedded designs.
Technical Context
The MSP430F5304IRGZR implements a unified clock system (UCS) with FLL stabilization, dual crystal support (XT1 for 32 kHz, XT2 up to 32 MHz), and internal sources (VLO, REFO). Its power management includes an integrated 3.3-V LDO, supply supervision, brownout reset, and five low-power modes - LPM3 (1.9 µA), LPM4 (1.1 µA), and LPM4.5 (0.18 µA).
Peripherals are mapped via port mapping controller on Port 4, enabling flexible USCI_B1 and USCI_A1 signal routing. Unlike higher-family variants, it integrates only one USCI module (not two), and omits Comparator_B - confirmed by device comparison table and functional block diagram specific to RGZ/PT packages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | 16-bit RISC CPU with constant generators; enables high code efficiency and deterministic real-time execution. |

| Communication | One USCI module configurable as UART (with auto-baud), IrDA, SPI master/slave, or I²C master/slave - routed via P4 port mapping. |
Pinout & Package
VQFN-48 (RGZ) package with 7 mm × 7 mm body and exposed thermal pad (to be connected to DVSS per TI recommendation).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RST/NMI/SBWTDIO | Reset / Non-maskable interrupt / JTAG debug input | Active-low reset with NMI capability; enables Spy-Bi-Wire programming and debugging without full JTAG header. |

FAQ
What is the maximum system clock frequency supported by the MSP430F5304IRGZR?
The MSP430F5304IRGZR supports up to 25 MHz system clock via its unified clock system (UCS) with FLL stabilization. This is achieved using the high-frequency crystal oscillator (XT2) up to 32 MHz or internal DCO calibrated against reference sources - enabling real-time control loops and fast ADC sampling at 200 kSPS.
Does the MSP430F5304IRGZR include a hardware real-time clock (RTC) module?
Yes, the MSP430F5304IRGZR includes a dedicated RTC_A module with alarm capability and calendar functionality. It operates in LPM3 with full RAM retention and draws only 1.9 µA at 2.2 V, using either a 32-kHz watch crystal (XT1) or the internal VLO as clock source - ideal for time-stamped data logging in battery-powered devices.
How many universal serial communication interfaces (USCI) does the MSP430F5304IRGZR have?
The MSP430F5304IRGZR has one USCI module, configurable as USCI_A0 (UART/IrDA/SPI) or USCI_B0 (SPI/I²C). Unlike MSP430F5308/5309/5310, it does not include a second USCI - confirmed in the Device Comparison table and functional block diagram for RGZ/PT packages.
What package type and dimensions does the MSP430F5304IRGZR use?
The MSP430F5304IRGZR uses a 48-pin VQFN package (RGZ suffix) measuring 7 mm × 7 mm with an exposed thermal pad. TI specifies connection of this pad to DVSS for optimal thermal performance - critical for sustained operation in compact enclosures or high-ambient environments.
Is the MSP430F5304IRGZR pin-compatible with other devices in the MSP430F53xx family?
The MSP430F5304IRGZR shares the same 48-pin VQFN (RGZ) footprint and basic pin assignments with MSP430F5308IRGZR and MSP430F5309IRGZR, but differs in peripheral pin availability - notably omitting USCI_B0 signals and Comparator_B inputs present on higher variants. Pin-to-pin compatibility is limited to core power, reset, and GPIO functions.
