Product details
Overview
MSP430F5418IPNR 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), three 16-bit timers (TA0/TA1/TB0), two USCI_A and two USCI_B modules (UART/IrDA/SPI/I²C), and integrated real-time clock. It operates from 2.2 V to 3.6 V and targets battery-powered sensor systems and digital timers.
For engineers reviewing the MSP430F5418IPNR datasheet, MSP430F5418IPNR pinout, MSP430F5418IPNR application, or MSP430F5418IPNR equivalent, this page delivers verified technical context, package-confirmed pin functions, low-power mode timing, ADC channel mapping, and direct alternative part comparisons for embedded design validation and BOM optimization.
Technical Context
The MSP430F5418IPNR implements a unified clock system (UCS) with FLL-based frequency stabilization, programmable LDO core regulation, and five low-power modes (LPM0–LPM4). Its CPUXV2 core supports 18-MHz operation and executes instructions in single-cycle or two-cycle latency depending on addressing mode.
Peripherals are memory-mapped and interrupt-driven: the 12-bit ADC12_A module supports autoscan across 16 channels with internal reference and sample-and-hold; DMA transfers support three-channel burst or single-mode transfers between peripherals and memory without CPU intervention.

FAQ
What is the maximum operating frequency of the MSP430F5418IPNR?
The MSP430F5418IPNR supports a maximum system clock frequency of 18 MHz, achieved via its digitally controlled oscillator (DCO) stabilized by the FLL loop using external crystals (XT2 up to 32 MHz) or internal references. This frequency enables real-time signal processing while maintaining sub-µA standby current in LPM3 mode.
Does the MSP430F5418IPNR include a hardware real-time clock (RTC)?
Yes, the MSP430F5418IPNR integrates a full-featured RTC_A module with calendar mode, alarm interrupts, and battery-backed operation. It can run from the 32-kHz crystal (XIN/XOUT) or internal VLO in LPM3, consuming only 2.6 µA at 3.0 V - making it ideal for time-stamped data logging in energy-constrained devices.
How many ADC channels does the MSP430F5418IPNR support, and what types are they?
The MSP430F5418IPNR features the ADC12_A module with 16 total channels: 14 external analog inputs (A0–A15, excluding A10/A11) and 2 internal channels (temperature sensor and VREF/2). All channels support autoscan mode, enabling unattended multi-sensor acquisition with configurable sample-and-hold timing.
What communication interfaces are available on the MSP430F5418IPNR?
The MSP430F5418IPNR provides four universal serial communication interfaces: USCI_A0 and USCI_A1 (each supporting UART, IrDA, and SPI), and USCI_B0 and USCI_B1 (each supporting I²C and SPI). This dual-A/dual-B configuration allows concurrent UART debugging, I²C sensor bus, and SPI flash memory access without resource conflict.
Is the MSP430F5418IPNR pin-compatible with other devices in the MSP430F54xx family?
Yes, the MSP430F5418IPNR in the 80-pin LQFP (PN) package shares identical pinout with MSP430F5437IPN and MSP430F5435IPN. This allows direct substitution within the same footprint when upgrading Flash size or adjusting peripheral count, provided firmware accommodates differences in USCI count and memory map.
