Product details
Overview
MSP430F5304IRGZT 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), one USCI module (UART/IrDA/SPI/I²C), 10-bit ADC with 6 external + 2 internal channels, RTC with alarm, 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 MSP430F5304IRGZT datasheet, MSP430F5304IRGZT pinout, MSP430F5304IRGZT application, or MSP430F5304IRGZT equivalent, key selection factors include its single-USCI configuration, 31 I/O count, VQFN-48 thermal pad layout, LPM4.5 shutdown current of 0.18 µA, and compatibility with TI's MSP430F5xx toolchain and bootloader.
Technical Context
The MSP430F5304IRGZT implements a unified clock system (UCS) with FLL-based frequency 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 voltage supervision, and five low-power modes (LPM0–LPM4.5).
It features a hardware multiplier supporting 32-bit operations, three-channel DMA, port mapping controller enabling flexible USCI signal routing on Port 4, and RTC_A with calibration and alarm functions - all optimized for deterministic wake-up (<5 µs from LPM3) and extended battery life in portable measurement applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Flash Memory | 8 KB - sufficient for compact firmware with real-time sensor processing and communication stacks |
| RAM | 6 KB - supports multiple buffered ADC conversions, UART receive/transmit queues, and RTC data retention |
| Operating Voltage | 1.8 V to 3.6 V - enables direct operation from single Li-ion, two alkaline, or regulated 3.3-V rails |
| Standby Current (LPM3) | 2.1 µA at 3 V - allows years of operation on coin-cell batteries when paired with RTC wake-up |
| Shutdown Current (LPM4.5) | 0.18 µA at 3 V - minimizes leakage during long-term storage or deep sleep between periodic measurements |
| ADC Resolution & Channels | 10-bit, 6 external + 2 internal inputs - supports thermistor, voltage monitoring, and internal temperature sensing without external mux |
| USCI Modules | 1 USCI (A1/B1 configurable) - provides UART for debugging or host interface, plus SPI/I²C for peripheral control with port-mapped flexibility |

FAQ
What is the maximum system clock frequency supported by the MSP430F5304IRGZT?
The MSP430F5304IRGZT supports a maximum system clock (MCLK) of 25 MHz, achieved via the FLL-controlled DCO or external high-frequency crystal (XT2) up to 32 MHz. This enables fast ADC sampling (200 kSPS), responsive UART communication, and efficient execution of real-time control algorithms within its ultra-low-power architecture.
Does the MSP430F5304IRGZT include an integrated voltage regulator?
Yes, the MSP430F5304IRGZT integrates a fully regulated 3.3-V LDO that accepts input from 1.8 V to 3.6 V. This eliminates the need for an external regulator, simplifies power design, and maintains stable core voltage across varying battery discharge curves - a key enabler for consistent ADC accuracy and timing performance.
How many capture/compare registers does the MSP430F5304IRGZT provide across its timers?
The MSP430F5304IRGZT provides 16 total capture/compare registers: Timer_A0 has five, Timer_A1 has three, Timer_A2 has three, and Timer_B0 has seven. These support complex PWM generation, input capture for pulse-width measurement, and quadrature decoding - essential for motor control and sensor signal conditioning tasks.
Can the MSP430F5304IRGZT operate with a 32-kHz watch crystal?
Yes, the MSP430F5304IRGZT supports a 32-kHz watch crystal connected to P5.4/XIN and P5.5/XOUT for the XT1 oscillator. This crystal drives the ACLK domain and enables the RTC_A module to maintain accurate real-time clocking and calendar functions with minimal power consumption in LPM3 mode.
What debug interface does the MSP430F5304IRGZT use?
The MSP430F5304IRGZT uses the 2-wire Spy-Bi-Wire (SBW) interface via the RST/NMI/SBWTDIO and TEST/SBWTCK pins. This compact debug solution requires only two pins for full programming, erasing, and real-time debugging - ideal for space-constrained PCB layouts while maintaining full JTAG-equivalent functionality.
