Texas Instruments MSP430F5418AIPN

Overview

MSP430F5418AIPN from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller featuring 128 KB flash, 16 KB RAM, a 12-bit ADC with 14 external + 2 internal channels, three 16-bit timers (TA0/TA1/TB0), two USCI_A and two USCI_B modules, and RTC functionality - deployed in battery-powered sensor systems and portable meters.

For engineers reviewing the MSP430F5418AIPN datasheet, MSP430F5418AIPN pinout, MSP430F5418AIPN application, or MSP430F5418AIPN equivalent, key selection criteria include LPM3 standby current (1.7 µA at 2.2 V), 80-pin LQFP package compatibility, dual-USCI support for UART/I²C/SPI coexistence, and integrated LDO with programmable core voltage.

Technical Context

The MSP430F5418AIPN implements a unified clock system with FLL stabilization, dual crystal support (32 kHz XT1 and up to 32 MHz XT2), and internal VLO/REFO sources - enabling precise timing across active and low-power modes. Its CPUXV2 core executes instructions in single-cycle mode with constant generators for optimized code density.

Power management integrates a fully regulated LDO, supply-voltage supervisor (SVS), brownout reset (BOR), and five low-power modes (LPM0–LPM4.5), with wake-up from LPM3 in 3.5 µs (typical). Peripheral interconnect uses DMA for zero-CPU-overhead transfers between ADC, USCI, and memory.

FAQ

What is the maximum system clock frequency supported by the MSP430F5418AIPN?

The MSP430F5418AIPN supports a maximum system clock (MCLK) frequency of 25 MHz, achieved via its digitally controlled oscillator (DCO) with FLL stabilization. This frequency is confirmed in the device's functional block diagram and electrical specifications table. The MSP430F5418AIPN maintains timing integrity across all operating voltages (1.8–3.6 V) and low-power modes, enabling deterministic real-time execution for time-critical sensor sampling and control loops.

Does the MSP430F5418AIPN include an integrated hardware multiplier?

Yes, the MSP430F5418AIPN includes a 32-bit hardware multiplier (MPY32) capable of performing signed/unsigned multiply, multiply-accumulate, and fractional operations in a single instruction cycle. This unit is explicitly documented in the "Features" section and functional block diagram. The MPY32 accelerates mathematical computations required in digital filtering, sensor calibration, and cryptographic functions - reducing CPU load and power consumption compared to software-based alternatives in the MSP430F5418AIPN.

How many universal serial communication interfaces (USCIs) does the MSP430F5418AIPN provide?

The MSP430F5418AIPN provides four USCIs: two USCI_A modules (UCA0, UCA1) supporting UART, IrDA, and SPI; and two USCI_B modules (UCB0, UCB1) supporting I²C and SPI. This configuration is verified in the Device Comparison table and functional block diagram. Each USCI operates independently, allowing concurrent communication with multiple peripherals - for example, UART to a host MCU, I²C to sensors, and SPI to an external DAC - without resource contention in the MSP430F5418AIPN.

What is the ADC resolution and channel count for the MSP430F5418AIPN?

The MSP430F5418AIPN integrates a 12-bit successive-approximation ADC (ADC12_A) with 14 external analog input channels and 2 internal channels (temperature sensor and VCC/2 reference). This specification is confirmed in the "Features" list, functional block diagram, and Device Comparison table. The ADC supports autoscan mode, sample-and-hold, and internal reference - enabling high-accuracy analog measurements essential for precision instrumentation within the MSP430F5418AIPN.

Is the MSP430F5418AIPN pin-compatible with other members of the MSP430F54xx family?

The MSP430F5418AIPN shares the same 80-pin LQFP (PN) package and pinout with MSP430F5437AIPN and MSP430F5435AIPN, as confirmed in Figure 7-2 and the Device Comparison table. All three devices have identical terminal numbering, signal assignments, and power/ground pin locations. However, it is not pin-compatible with 100-pin or 113-pin variants (e.g., MSP430F5438AIPZ or MSP430F5419AIPZ), which use different package footprints and signal mappings - requiring PCB redesign for migration to those MSP430F5418AIPN alternatives.
