Product details
Overview
MSP430F5340IRGZR from Texas Instruments is a 16-bit ultra-low-power mixed-signal microcontroller featuring 64 KB Flash, 6 KB RAM, four 16-bit timers (TA0/TA1/TA2/TB0), dual USCI modules (UART/IrDA/SPI/I²C), and a 12-bit ADC with autoscan-designed for battery-powered sensor nodes and data loggers operating at 1.8–3.6 V.
For engineers reviewing the MSP430F5340IRGZR datasheet, MSP430F5340IRGZR pinout, MSP430F5340IRGZR application, or MSP430F5340IRGZR equivalent, key selection criteria include LPM3 standby current (1.9 µA), 38 GPIOs in VQFN-48, RTC integration, and dual-USCI peripheral flexibility for wired sensor interface design.
Technical Context
The MSP430F5340IRGZR implements a CPUXV2 16-bit RISC core with constant generator and hardware multiplier supporting 32-bit operations. Its unified clock system integrates FLL-based DCO stabilization, dual crystal oscillators (XT1 up to 32 kHz, XT2 up to 32 MHz), REFO and VLO internal sources, and programmable LDO for core voltage regulation (PMMCOREVx = 0–3).
Peripherals are tightly coupled via a 3-channel DMA controller and port mapping logic enabling dynamic reconfiguration of USCI_A1/USCI_B1 functions. The 12-bit ADC12_A supports up to 9 channels (7 external, 2 internal), sample-and-hold, and internal reference-operating at 200 ksps with linearity ±1 LSB (INL) using internal reference.

FAQ
What is the maximum system clock frequency supported by the MSP430F5340IRGZR?
The MSP430F5340IRGZR supports up to 25 MHz MCLK when PMMCOREVx = 3 and VCC ≥ 2.4 V. At lower core voltage settings (PMMCOREVx = 0–2), the maximum frequency is reduced to 8 MHz, 12 MHz, or 20 MHz respectively-ensuring stable operation across its 1.8–3.6 V supply range. This scalability allows designers to optimize power versus performance for each application phase.
Does the MSP430F5340IRGZR include an integrated real-time clock (RTC)?
Yes, the MSP430F5340IRGZR integrates a dedicated RTC_A module with calendar mode, alarm interrupt, and battery-backed operation when paired with a 32.768 kHz crystal on XT1 pins (P5.4/P5.5). It maintains timekeeping in LPM3 with only 1.9 µA current draw, eliminating the need for external RTC ICs in time-sensitive sensor and logging applications.
How many analog input channels does the MSP430F5340IRGZR ADC support?
The MSP430F5340IRGZR features a 12-bit ADC12_A with support for 9 total input channels: 7 external analog inputs (A0–A6 mapped to P6.x/P5.x pins) and 2 internal sources (temperature sensor and VMID). The autoscan function allows automatic sequencing across all enabled channels without CPU intervention-ideal for multi-sensor systems.
Can the MSP430F5340IRGZR operate from a single 1.8 V supply?
Yes, the MSP430F5340IRGZR is fully specified for operation down to 1.8 V at PMMCOREVx = 0, supporting active-mode execution at up to 8 MHz. Its supply-voltage supervisor (SVS) and brownout reset (BOR) ensure reliable startup and operation across the entire 1.8–3.6 V range-making it suitable for coin-cell and energy-harvesting power sources.
What debug interface does the MSP430F5340IRGZR use?
The MSP430F5340IRGZR supports both 4-wire JTAG and 2-wire Spy-Bi-Wire (SBW) debugging via dedicated pins (PJ.0–PJ.3 and RST/NMI/SBWTDIO). SBW mode uses only two pins-RST/NMI/SBWTDIO and TEST/SBWTCK-enabling in-circuit programming and real-time debugging with minimal PCB footprint and no external debug adapter required.
