Product details
Overview
MSP430F2418TPM from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller with 116KB+256B flash, 8KB RAM, 12-bit ADC, dual USCI_A/USCI_B modules (UART/I²C/SPI), 16-bit Timer_A and Timer_B, on-chip comparator, and supply voltage supervisor - designed for battery-powered sensor nodes and portable medical devices operating from 1.8 V to 3.6 V.
For engineers reviewing the MSP430F2418TPM datasheet, MSP430F2418TPM pinout, MSP430F2418TPM application, or MSP430F2418TPM equivalent, key selection criteria include LQFP-64 package compatibility, absence of DAC12 and DMA (vs. F261x), 48 I/O capability, calibrated DCO wake-up <1 µs, and support for IrDA, LIN, and hardware multiplier functions.
Technical Context
The MSP430F2418TPM implements a 16-bit CPU with constant generators and 16-bit registers for optimized code efficiency in low-power embedded control. Its basic clock system integrates DCO, LFXT1 (32 kHz crystal), and VLO oscillators, enabling five low-power modes and sub-1 µs wake-up from LPM4.
Peripheral integration includes two independent USCI modules (USCI_A0/A1 for UART/LIN/IrDA/SPI; USCI_B0/B1 for I²C/SPI), 12-bit ADC12 with internal reference and autoscan, and Timer_B7 with shadow registers for precise PWM and capture timing - all accessible via 48 GPIO pins in the PM package.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | 16-bit RISC CPU with 62.5-ns instruction cycle; enables deterministic real-time control at low clock rates. |
| Flash / RAM | 116KB + 256B flash memory and 8KB RAM; supports firmware updates and complex sensor fusion algorithms. |
| ADC Resolution | 12-bit ADC12 with 8-channel input, internal reference, sample-and-hold, and autoscan; suitable for precision analog sensing. |
| USCI Modules | Four USCI interfaces: USCI_A0/A1 (UART/LIN/IrDA/SPI) and USCI_B0/B1 (I²C/SPI); enables concurrent wired communication protocols. |
| Power Modes | Active mode: 365 µA @ 1 MHz, 2.2 V; Standby (VLO): 0.5 µA; Off (RAM retention): 0.1 µA - extends coin-cell battery life to years. |
| Wake-up Time | <1 µs from standby mode; critical for responsive event-driven systems like wearable health monitors. |
| Operating Voltage | 1.8 V to 3.6 V supply range; compatible with single-cell Li-ion, Li-poly, or dual alkaline batteries without regulation. |
Pinout & Package
LQFP-64 package (10 mm × 10 mm, 0.5 mm pitch), nonmagnetic option available for medical imaging applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RST/NMI | Reset / Non-maskable interrupt input | Hardware reset initiation and high-priority fault handling; supports JTAG debugging interface. |
| TCK, TMS, TDI/TCLK, TDO/TDI | JTAG emulation interface | Full boundary-scan and in-circuit debug capability without requiring dedicated debug pins beyond standard JTAG. |

| VREF+, VREF−, VeREF+ | ADC reference voltage inputs | Accept external reference or use internal 1.5/2.0/2.5 V references; VeREF+ supports buffered output for external circuit biasing. |
Key Features
| Feature | Design Value |
|---|---|
| Calibrated DCO oscillator | Enables wake-up from LPM4 to active mode in <1 µs without external crystal - reduces BOM cost and board space. |
| Hardware multiplier (MPY/MPYS/MAC/MACS) | Executes 16×16-bit multiply in one cycle; accelerates filtering, FFT, and sensor calibration math in firmware. |
| USCI_A with IrDA encoder/decoder | Direct IrDA physical layer support eliminates need for external transceivers in remote-control or diagnostic interfaces. |
| Supply voltage supervisor (SVS) with programmable threshold | Prevents erratic operation during brownout by triggering reset or interrupt at user-defined VCC level (e.g., 1.9 V). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F2417TPM | Same package and peripherals, but 92KB+256B flash and 8KB RAM - 24KB less program memory. | Suitable for simpler firmware with smaller code footprint; not recommended if bootloader or future feature expansion is required. | Select when cost sensitivity outweighs memory headroom and no DAC/DMA is needed. |
| MSP430F2618TPM | Identical flash/RAM and package, but adds DAC12 (dual 12-bit voltage-output DACs) and three-channel DMA. | Required for closed-loop analog control (e.g., sensor excitation, calibration offset correction) or high-throughput data movement without CPU load. | Choose only if DAC or DMA functionality is essential; otherwise, MSP430F2418TPM offers lower power and identical core performance. |
Compared with MSP430F2417TPM, the MSP430F2418TPM provides 24KB more flash for larger firmware or secure boot partitions; compared with MSP430F2618TPM, it omits DAC12 and DMA - reducing dynamic power and simplifying design where those features are unused.

FAQ
What is the maximum ADC sampling rate supported by the MSP430F2418TPM?
The MSP430F2418TPM ADC12 module supports up to 200 kSPS with internal reference and 7 MHz ADCCLK. Conversion time is 1.86 µs minimum (12-bit, no oversampling), enabling real-time monitoring of fast-changing analog signals such as audio pre-amplifier outputs or motor current feedback.
Does the MSP430F2418TPM support hardware UART autobaud detection?
Yes, the MSP430F2418TPM USCI_A modules support automatic baud-rate detection in UART mode. This feature allows the MSP430F2418TPM to synchronize to incoming data streams without prior knowledge of the transmitter's baud rate - useful in legacy system integration and field-service diagnostics.
Is the MSP430F2418TPM pin-compatible with the MSP430F2618TPM in the LQFP-64 package?
Yes, the MSP430F2418TPM and MSP430F2618TPM share identical LQFP-64 pinouts and mechanical dimensions. However, pins P6.5, P6.6, P6.7, and VeREF+ have additional DAC12 functionality on the MSP430F2618TPM - unused but electrically safe on the MSP430F2418TPM.
What is the purpose of the SVSOUT pin (P5.7) on the MSP430F2418TPM?
The SVSOUT pin (P5.7) on the MSP430F2418TPM provides an open-drain output that asserts low when the supply voltage drops below the programmed SVS threshold. It can drive external circuitry - such as a supervisor IC or LED indicator - independently of the internal reset assertion, enabling graceful shutdown sequences.
Can the MSP430F2418TPM operate from a 3.3 V supply while maintaining full specification compliance?
Yes, the MSP430F2418TPM is fully specified from 1.8 V to 3.6 V. At 3.3 V, it delivers maximum CPU performance (up to 16 MHz DCO), lowest noise ADC operation, and guaranteed timing margins across all peripherals - making it ideal for systems powered directly from regulated 3.3 V rails.
