Product details
Overview
MSP430F5418IPN 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), four USCI modules (2 UART/IrDA/SPI + 2 I²C/SPI), and RTC functionality - deployed in battery-powered sensor systems and digital timers requiring sub-µA standby current.
For engineers reviewing the MSP430F5418IPN datasheet, MSP430F5418IPN pinout, MSP430F5418IPN application, or MSP430F5418IPN equivalent, key selection criteria include LPM3 current (2.6 µA), 80-pin LQFP package compatibility, dual USCI_A/B interface count, integrated LDO core regulation, and 18-MHz max system clock for real-time control tasks.
Technical Context
The MSP430F5418IPN implements a unified clock system (UCS) with FLL stabilization, VLO/REFO internal sources, and support for 32-kHz crystals and up to 32-MHz high-frequency crystals. Its CPUXV2 core executes instructions in single-cycle mode with constant generators for optimized code density.
It integrates a 3-channel DMA controller, hardware multiplier for 32-bit operations, and programmable drive-strength I/O ports across eight 8-bit ports (P1–P8), with interrupt-capable pins on all ports and dedicated peripheral mapping for timer capture/compare, USCI signal routing, and ADC analog inputs.

FAQ
What is the maximum operating frequency of the MSP430F5418IPN?
The MSP430F5418IPN supports a maximum system clock frequency of 18 MHz, achievable via the FLL-stabilized DCO or external high-frequency crystal (up to 32 MHz). This allows real-time execution of control algorithms with sub-microsecond interrupt latency, confirmed in Section 5.20 of the SLAS612F datasheet.
Does the MSP430F5418IPN include a hardware real-time clock (RTC)?
Yes, the MSP430F5418IPN integrates a full-featured RTC_A module with calendar mode, alarm interrupts, and battery-backup capability. It operates in LPM3 with a 32.768-kHz crystal connected to P7.0/XIN and P7.1/XOUT, consuming only 2.6 µA at 3.0 V - verified in Section 1.1 and Table 5.5 of the datasheet.
How many analog input channels does the MSP430F5418IPN ADC support?
The MSP430F5418IPN features a 12-bit ADC12_A module with 14 external analog input channels (A0–A15, excluding A10/A11) and 2 internal channels (temperature sensor and VREF+/VeREF+), totaling 16 selectable inputs. Autoscan mode enables sequential conversion without CPU intervention - specified in Section 1.1 and Table 3-1.
Is the MSP430F5418IPN pin-compatible with other devices in the MSP430F54xx family?
The MSP430F5418IPN shares the same 80-pin LQFP (PN) package and pinout with MSP430F5437IPN and MSP430F5435IPN, as confirmed in Figure 4-2 and Table 4-1 of the SLAS612F datasheet. However, Flash size and USCI count differ, so firmware and schematic validation is required before substitution.
What power supply requirements does the MSP430F5418IPN have?
The MSP430F5418IPN operates from a single 2.2 V to 3.6 V supply, with separate DVCC/DVSS and AVCC/AVSS domains. Its integrated LDO supports programmable core voltage (1.8 V–2.2 V), and supply supervision includes brownout reset (BOR) and SVS/SVM thresholds - detailed in Sections 1.1, 5.21, and 5.22 of the datasheet.
