Product details
Overview
MSP430F5418AIPNR from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller with 128 KB flash, 16 KB RAM, 12-bit ADC (14 external + 2 internal channels), dual USCI modules (UART/IrDA/SPI/I²C), three 16-bit timers (TA0/TA1/TB0), RTC, and hardware multiplier - deployed in battery-powered sensor nodes and handheld meters.
For engineers reviewing the MSP430F5418AIPNR datasheet, MSP430F5418AIPNR pinout, MSP430F5418AIPNR application, or MSP430F5418AIPNR equivalent, key selection criteria include LPM3 standby current (1.7 µA), 80-pin LQFP package compatibility, 25-MHz max system clock, integrated LDO core regulation, and dual-USCI peripheral count for mixed-protocol communication.
Technical Context
This device implements a unified clock system with FLL stabilization, VLO and REFO internal sources, and support for 32-kHz crystals and up to 32-MHz high-frequency crystals. Its power-management architecture includes programmable core voltage via integrated LDO, brownout detection, and supply supervision.
The MCU integrates three independent 16-bit timers: TA0 (5 capture/compare registers), TA1 (3 registers), and TB0 (7 shadow registers), plus a real-time clock module with alarm capability and a 12-bit ADC with autoscan, internal reference, and sample-and-hold - all operating under multiple low-power modes (LPM0–LPM4.5).

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F5437AIPN | 256 KB flash, 2 USCI modules, same 80-pin LQFP package and peripheral set | Higher flash capacity supports larger firmware with advanced encryption or BLE stack integration | Select when firmware growth headroom or future feature expansion is required without PCB change |

FAQ
What is the maximum operating frequency of the MSP430F5418AIPNR?
The MSP430F5418AIPNR supports a maximum system clock frequency of 25 MHz, achieved via its digitally controlled oscillator (DCO) with FLL stabilization. This frequency is validated across the full operating voltage range (1.8 V to 3.6 V) and enables high-throughput data acquisition and real-time control loops without compromising ultra-low-power operation in active mode.
Does the MSP430F5418AIPNR include an integrated real-time clock (RTC)?
Yes, the MSP430F5418AIPNR includes a dedicated RTC_A module with calendar functionality, alarm capability, and independent operation in LPM3. It maintains accurate timekeeping using a 32-kHz crystal or internal VLO source, and retains full RAM content during RTC-active standby - enabling multi-year battery life in time-critical monitoring applications.
How many analog input channels does the 12-bit ADC on the MSP430F5418AIPNR support?
The MSP430F5418AIPNR features a 12-bit ADC12_A module supporting 14 external analog input channels (A0–A15, excluding A10/A11) and 2 internal channels (temperature sensor and VCC/2). The autoscan function allows automatic sequencing across selected channels without CPU involvement, reducing firmware overhead in multi-sensor systems.
What debug interface does the MSP430F5418AIPNR use?
The MSP430F5418AIPNR uses the 2-wire Spy-Bi-Wire (SBW) interface for programming and debugging, accessible via the RST/NMI/SBWTDIO and TEST/SBWTCK pins. This interface is fully compatible with TI's MSP-FET and IAR Embedded Workbench, and requires no external voltage - enabling in-system debugging and flash programming with minimal pin count.
Is the MSP430F5418AIPNR pin-compatible with other devices in the MSP430F54xxA family?
The MSP430F5418AIPNR shares the same 80-pin LQFP (PN) package and pinout with MSP430F5437AIPN and MSP430F5435AIPN, making it mechanically and electrically compatible within that package group. However, differences in flash size and USCI count mean firmware and peripheral initialization must be verified per device - it is not a drop-in replacement without software review.
