Product details
Overview
MSP430F5325IPN from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller with 64 KB flash, 6 KB + 2 KB RAM, integrated 3.3-V LDO, four 16-bit timers (TA0/TA1/TA2/TB0), dual USCI modules (UART/IrDA/SPI/I²C), 12-bit 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 sub-2 µA standby current and 3.5 µs wake-up.
For engineers reviewing the MSP430F5325IPN datasheet, MSP430F5325IPN pinout, MSP430F5325IPN application, or MSP430F5325IPN equivalent, key selection criteria include its 63 I/O count, 14-channel ADC input capability, LQFP-80 package compatibility, and verified LPM3 current of 1.9 µA at 2.2 V - critical for long-life portable instrumentation designs.
Technical Context
The MSP430F5325IPN implements a unified clock system with FLL-based frequency stabilization, dual crystal support (XT1 for 32-kHz RTC, XT2 up to 32 MHz), and three internal sources (VLO, REFO, DCO). Its power management includes programmable core voltage regulation via integrated LDO and brownout detection with hysteresis.
Peripherals are memory-mapped and interrupt-driven: Timer_A instances support capture/compare/PWM with up to five registers (TA0), while Timer_B (TB0) provides seven shadow-capable compare registers. The ADC12_A module supports autoscan across 16 total channels with internal reference and sample-and-hold.

FAQ
What is the maximum system clock frequency supported by the MSP430F5325IPN?
The MSP430F5325IPN supports a maximum system clock (MCLK) frequency of 25 MHz, achieved via the integrated FLL loop with XT2 crystal input up to 32 MHz or internal DCO calibration. This enables high-speed computation while maintaining ultra-low-power operation through dynamic clock gating and multiple low-power modes.
Does the MSP430F5325IPN include an integrated voltage regulator?
Yes, the MSP430F5325IPN integrates a fully programmable low-dropout (LDO) regulator that supplies the core logic (VCORE) from the DVCC rail. It supports selectable core voltages from 1.8 V to 3.0 V, enabling dynamic voltage scaling to optimize energy efficiency based on processing load and clock frequency.
How many analog input channels does the ADC12_A module support on the MSP430F5325IPN?
The ADC12_A module on the MSP430F5325IPN supports 16 total channels: 14 external analog inputs (A0–A13) and 2 internal sources (temperature sensor and VCC/2 reference). All channels are accessible via the same 12-bit SAR architecture with autoscan, sample-and-hold, and configurable conversion timing.
What debug interface does the MSP430F5325IPN use, and is external hardware required?
The MSP430F5325IPN uses the 4-wire Spy-Bi-Wire (SBW) interface via the RST/NMI/SBWTDIO and TEST/SBWTCK pins. No external voltage translator or dedicated debugger is required - standard TI MSP-FET or open-source SBW adapters connect directly for programming and real-time debugging.
Is the MSP430F5325IPN pin-compatible with other devices in the F532x family?
Yes, the MSP430F5325IPN is pin-compatible with MSP430F5327IPN and MSP430F5329IPN in the LQFP-80 (PN) package, sharing identical pin functions, electrical characteristics, and mechanical dimensions - enabling direct substitution within the same PCB layout when flash/RAM requirements align.
