Product details
Overview
MSP430F5310IRGZT from Texas Instruments is a 16-bit ultra-low-power mixed-signal microcontroller featuring 32 KB Flash, 6 KB RAM, dual USCI modules (UART/IrDA/SPI/I²C), 10-bit ADC with 12 channels (10 external + 2 internal), RTC, four 16-bit timers (TA0/TA1/TA2/TB0), hardware multiplier, and integrated 3.3-V LDO. It operates from 1.8 V to 3.6 V and targets battery-powered sensor nodes and portable instrumentation.
For engineers reviewing the MSP430F5310IRGZT datasheet, MSP430F5310IRGZT pinout, MSP430F5310IRGZT application, or MSP430F5310IRGZT equivalent, key selection criteria include its 48-pin VQFN (RGZ) package with 31 GPIOs, sub-2 µA LPM3 current at 3 V, <5 µs wake-up time, and dual-USCI flexibility for concurrent serial protocols in space-constrained designs.
Technical Context
The MSP430F5310IRGZT implements the MSP430F5xx architecture with CPUXV2 core, unified clock system (UCS) supporting FLL-stabilized DCO, XT1 (32 kHz crystal), XT2 (up to 32 MHz), REFO, and VLO. Its port mapping controller enables dynamic remapping of USCI functions onto Port 4 pins.
It integrates a programmable LDO for core voltage regulation, supply-voltage supervision with brownout detection, and three-channel DMA to offload CPU during peripheral transfers-enabling deterministic real-time response in low-power motor control and sensor acquisition loops.

FAQ
What is the maximum system clock frequency supported by the MSP430F5310IRGZT?
The MSP430F5310IRGZT supports up to 25 MHz system clock frequency via its unified clock system (UCS), using either the internal DCO stabilized by the FLL or an external high-frequency crystal (XT2) up to 32 MHz. This enables high-speed computation while maintaining ultra-low-power operation in active mode at 195 µA/MHz typical.
Does the MSP430F5310IRGZT support crystal oscillators for both low- and high-frequency operation?
Yes, the MSP430F5310IRGZT supports dual crystal oscillators: XT1 accepts a 32.768-kHz watch crystal for RTC and low-power timing, while XT2 supports crystals up to 32 MHz for high-speed system clocking. Both are accessible via dedicated P5.4/XIN and P5.5/XOUT pins in the RGZ package.
How many general-purpose I/O pins does the MSP430F5310IRGZT provide in its 48-pin VQFN package?
The MSP430F5310IRGZT in the 48-pin VQFN (RGZ) package provides 31 general-purpose I/O pins, distributed across Ports P1–P6 and PU. All pins support configurable pull-up/down resistors, Schmitt-trigger inputs, and programmable drive strength-enabling robust interfacing with sensors, displays, and communication peripherals.
Can the MSP430F5310IRGZT operate from a single 3.0-V supply without external regulators?
Yes, the MSP430F5310IRGZT integrates a fully functional 3.3-V LDO that regulates DVCC from a single 1.8–3.6-V supply. With proper decoupling (DVCC1/DVCC2, VCORE), it delivers stable core voltage and eliminates need for external regulators-simplifying power design for compact, battery-operated devices.
What debug interface does the MSP430F5310IRGZT use, and what pins are required?
The MSP430F5310IRGZT uses the 4-wire Spy-Bi-Wire (SBW) interface for programming and debugging, requiring only RST/NMI/SBWTDIO and TEST/SBWTCK pins. This two-pin debug capability minimizes footprint impact and enables in-system firmware updates without dedicated JTAG header space.
