Product details
Overview
MSP430F5327IPN from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller with 96 KB flash, 8 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, hardware multiplier, and 63 GPIO pins in an 80-pin LQFP package - deployed in battery-powered sensor nodes and portable data loggers.
For engineers reviewing the MSP430F5327IPN datasheet, MSP430F5327IPN pinout, MSP430F5327IPN application, or MSP430F5327IPN equivalent, key selection criteria include active-mode current at 8 MHz (150 µA/MHz RAM execution), standby-mode current (1.9 µA with RTC active), 3.5-µs wake-up time, 14-channel ADC autoscan capability, and LQFP-80 package compatibility with MSP430F5329IPN/MSP430F5325IPN layouts.
Technical Context
The MSP430F5327IPN 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 provide capture/compare/PWM with up to five registers (TA0), while Timer_B (TB0) offers seven shadow registers for synchronized PWM. The two USCIs operate independently - USCI_Ax supports UART with auto-baud detection and IrDA, USCI_Bx handles I²C and SPI - enabling concurrent serial protocols without resource contention.
Key Specifications

FAQ
What is the maximum system clock frequency supported by the MSP430F5327IPN?
The MSP430F5327IPN supports a maximum system clock frequency of 25 MHz, achieved via its digitally controlled oscillator (DCO) stabilized by the FLL using XT2 (up to 32 MHz), REFO, or VLO references. This frequency enables real-time processing of sensor data while maintaining ultra-low power consumption in active mode.
Does the MSP430F5327IPN include an integrated voltage regulator?
Yes, the MSP430F5327IPN integrates a fully functional 3.3-V low-dropout (LDO) regulator with programmable core voltage output (VCORE). This eliminates the need for an external regulator in most applications and provides stable core supply across the 1.8–3.6 V input range, improving noise immunity for analog peripherals like the ADC and comparator.
How many I/O pins does the MSP430F5327IPN provide, and what is their drive strength?
The MSP430F5327IPN provides 63 general-purpose I/O pins across ports P1–P8, PJ, and PU. Each pin supports programmable full or reduced drive strength, with typical output current of ±12 mA (full) and ±6 mA (reduced) at 3 V - enabling direct LED driving or robust interfacing with industrial-level logic without external buffers.
Can the MSP430F5327IPN operate from a coin-cell battery?
Yes, the MSP430F5327IPN operates from 1.8 V to 3.6 V and draws only 1.9 µA in LPM3 (RTC active) and 0.18 µA in LPM4.5 (shutdown), making it ideal for coin-cell (e.g., CR2032) operation. Its integrated LDO maintains stable VCORE down to 1.8 V input, and the 3.5-µs wake-up time minimizes active-mode energy per sensing event.
What development tools are officially supported for the MSP430F5327IPN?
Texas Instruments officially supports the MSP430F5327IPN with the MSP-FET debugger, Code Composer Studio IDE, and MSP430Ware peripheral driver library. Hardware evaluation is enabled via the MSP-TS430PN80 target socket board, which mates directly with the 80-pin LQFP package of the MSP430F5327IPN for rapid prototyping and validation.
