Product details
Overview
MSP430F5329IPNR from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller with 128 KB flash, 10 KB RAM, integrated 3.3-V LDO, four 16-bit timers (TA0/TA1/TA2/TB0), dual USCI modules (UART/IrDA/SPI/I²C), 12-bit 200-ksps ADC with 14 external + 2 internal channels, RTC, and 63 GPIO pins in an 80-pin LQFP package. It targets battery-powered sensor systems and data loggers requiring fast wake-up (3.5 µs) and sub-µA standby current.
For engineers reviewing the MSP430F5329IPNR datasheet, MSP430F5329IPNR pinout, MSP430F5329IPNR application, or MSP430F5329IPNR equivalent, key selection criteria include its 128 KB flash capacity, 63 I/O count, LQFP-80 thermal pad layout, RTC+DMA+ADC12_A integration, and compatibility with TI's MSP430F5xx toolchain and development boards like MSP-TS430PN80.
Technical Context
The MSP430F5329IPNR implements a CPUXV2 core with constant generators and 16-bit register architecture, paired with a unified clock system featuring FLL stabilization, XT1 (32-kHz crystal), XT2 (up to 32-MHz crystal), REFO, and VLO oscillators. Its power management includes programmable LDO core voltage regulation, SVS/SVM brownout supervision, and five low-power modes (LPM0–LPM4.5).
Peripherals are memory-mapped and interrupt-driven: three Timer_A instances (5/3/3 CC registers), one Timer_B (7 CC shadow registers), two USCIs supporting concurrent UART/IrDA/SPI and I²C protocols, and ADC12_A with autoscan, sample-and-hold, and internal reference - all operating under full RAM retention in LPM3/LPM4.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F5328IRGC | Same core/peripherals but 47 I/O pins, 10 ext + 2 int ADC channels, 64-pin VQFN package. | Suitable for space-constrained designs with fewer external sensors or simpler I/O requirements. | Select when PCB area is limited and full 63-pin I/O count is unnecessary; verify thermal pad soldering per TI's RGC guidelines. |
| MSP430F5327IPNR | 96 KB flash, 8 KB RAM, identical 80-pin LQFP package and 63 I/O count; same ADC/USCI/timer configuration. | Preferred where firmware size < 96 KB suffices and cost optimization is prioritized over flash headroom. | Drop-in replacement for footprint and pinout; validate flash usage margin and confirm LDO behavior matches design requirements. |
Compared with MSP430F5328IRGC, the MSP430F5329IPNR delivers 16 more I/O pins and 4 additional ADC external channels - essential for multi-sensor nodes. Against MSP430F5327IPNR, it adds 32 KB flash and 2 KB RAM, enabling larger firmware with OTA update capability and extended data buffering.

FAQ
What is the maximum system clock frequency supported by the MSP430F5329IPNR?
The MSP430F5329IPNR supports up to 25 MHz system clock frequency using the FLL-controlled DCO with XT2 crystal (up to 32 MHz) or internal reference sources. This is confirmed in Section 1 of the SLAS678G datasheet under "16-bit RISC architecture, extended memory, up to 25-MHz system clock". The device achieves this speed while maintaining ultra-low active-mode current of 290 µA/MHz at 3 V.
Does the MSP430F5329IPNR include hardware debugging support?
Yes, the MSP430F5329IPNR includes full JTAG and Spy-Bi-Wire (SBW) debug interfaces via dedicated pins (RST/NMI/SBWTDIO, PJ.0–PJ.3, TEST/SBWTCK). These enable in-circuit emulation, flash programming, and real-time breakpoint debugging using TI's MSP-FET and Code Composer Studio. Section 9.6 and Figure 7-1 of SLAS678G confirm SBW signal mapping on the 80-pin PN package.
Can the MSP430F5329IPNR operate from a single 1.8-V supply?
Yes, the MSP430F5329IPNR operates across a supply voltage range of 1.8 V to 3.6 V, as specified in Section 1 ("Low supply voltage range: 3.6 V down to 1.8 V") and Section 8.3 ("Recommended Operating Conditions"). At 1.8 V, it supports reduced maximum clock frequency and enters specific low-voltage operating modes, with brownout detection active to prevent erratic behavior.
How many independent capture/compare channels does the MSP430F5329IPNR provide?
The MSP430F5329IPNR provides 18 independent capture/compare channels: Timer_A0 has 5, Timer_A1 has 3, Timer_A2 has 3, and Timer_B0 has 7 - totaling 18 channels. This is explicitly stated in Section 1 ("16-bit timer TA0… five capture/compare registers", etc.) and Table 6-1, which lists "5, 3, 3" for Timer_A and "7" for Timer_B.
Is the RTC module in the MSP430F5329IPNR battery-backed?
No, the RTC_A module in the MSP430F5329IPNR is not battery-backed; it retains functionality only during LPM3/LPM4 with main supply applied. It requires continuous DVCC power and uses the 32-kHz XT1 crystal or VLO for timekeeping. Section 3 states "Standby mode (LPM3): real-time clock (RTC) with crystal… full RAM retention", confirming RTC operation depends on active VCC - no separate VBAT rail is provided.
