Product details
Overview
MSP430F2418TPMR 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), two 16-bit timers (Timer_A3 and Timer_B7), and on-chip comparator - deployed in battery-powered sensor nodes and portable medical meters requiring sub-1µs wake-up and <0.1µA off-mode retention.
For engineers reviewing the MSP430F2418TPMR datasheet, MSP430F2418TPMR pinout, MSP430F2418TPMR application, or MSP430F2418TPMR equivalent, key selection criteria include LQFP-64 package compatibility, absence of DAC12/DMA (vs. F261x), calibrated DCO stability over 0°C–85°C, and support for IrDA encoding, bootloader (BSL), and nonmagnetic operation in medical imaging systems.
Technical Context
The MSP430F2418TPMR implements a 16-bit CPU with constant generators and three low-power modes (LPM0–LPM4) optimized for extended battery life. Its clock system integrates a calibrated DCO (1–16 MHz), LFXT1 (32.768 kHz crystal), and VLO oscillator, enabling sub-1 µs wake-up from standby mode.
Peripheral integration includes ADC12 with internal reference and autoscan across 8 channels, two independent USCI modules supporting simultaneous UART/I²C/SPI, and Timer_B7 with shadow registers for glitch-free PWM generation - all operating within 1.8–3.6 V supply range and qualified for industrial temperature range (–40°C to 85°C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | 16-bit RISC CPU with 62.5-ns instruction cycle; enables high code efficiency in memory-constrained embedded firmware. |
| Flash / RAM | 116KB + 256B flash memory and 8KB RAM; supports complex sensor fusion algorithms and local data buffering without external memory. |
| ADC Resolution | 12-bit SAR ADC with internal reference, sample-and-hold, and autoscan; delivers ±1 LSB INL for precision analog signal acquisition. |
| Timers | Timer_A3 (3 capture/compare registers) and Timer_B7 (7 capture/compare registers with shadow registers); enables multi-channel PWM, input capture, and time-critical event sequencing. |
| USCI Interfaces | Four USCI modules: USCI_A0/A1 (UART/LIN/IrDA/SPI) and USCI_B0/B1 (I²C/SPI); allows concurrent wired communication with sensors, displays, and host controllers. |
| Supply Current | Active mode: 365 µA at 1 MHz/2.2 V; Standby (VLO): 0.5 µA; Off mode (RAM retention): 0.1 µA - critical for multi-year battery operation. |
| Wake-up Time | <1 µs from standby mode; ensures rapid response to external interrupts in real-time monitoring applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F2417TPMR | Same core/peripherals but 92KB+256B flash and identical 8KB RAM; no DAC12/DMA. | Suitable where firmware footprint is smaller and cost sensitivity outweighs flash headroom. | Select when application binary fits within 92KB and future feature expansion is unlikely. |
| MSP430F2618TPMR | Includes DAC12 (dual 12-bit voltage-output DACs) and 3-channel DMA; same flash/RAM and package. | Required for closed-loop analog control (e.g., sensor biasing, waveform generation) or high-throughput data movement. | Choose only if DAC or DMA functionality is explicitly needed - adds complexity and cost without benefit otherwise. |
Compared with MSP430F2417TPMR, the MSP430F2418TPMR offers 24KB more flash for larger firmware or calibration data storage; compared with MSP430F2618TPMR, it omits DAC12 and DMA - reducing die area, power, and cost while retaining identical timing, communication, and analog acquisition capabilities for pure sensor-readout roles.

FAQ
What is the maximum ADC sampling rate supported by the MSP430F2418TPMR?
The MSP430F2418TPMR ADC12 module supports a maximum conversion clock (fADC12CLK) of 7 MHz. With minimum conversion time of 1.86 µs, this enables up to ~537 kSPS in single-channel mode. In autoscan mode across 8 channels, effective throughput depends on channel count and sampling interval configuration - verified in Section 8.46 of the SLAS541M datasheet.
Does the MSP430F2418TPMR include a hardware multiplier?
Yes, the MSP430F2418TPMR includes a 16-bit hardware multiplier (MPY, MPYS, MAC, MACS) capable of completing 16×16-bit multiply operations in one CPU cycle. This accelerates fixed-point math used in sensor linearization, FIR filtering, and PID control loops without consuming CPU bandwidth.
Is the MSP430F2418TPMR pin-compatible with the MSP430F2618TPMR in the LQFP-64 package?
No - while both share the LQFP-64 (PM) package footprint, the MSP430F2418TPMR lacks DAC12 and DMA functionality. Pins P6.5/A5, P6.6/A6, and P6.7/A7/SVSIN are dedicated analog inputs on the MSP430F2418TPMR, whereas they serve as DAC1/DAC0/DAC1 outputs on the MSP430F2618TPMR. Direct replacement requires PCB redesign.
What communication protocols does the USCI module in the MSP430F2418TPMR support?
The MSP430F2418TPMR features four USCI modules: USCI_A0 and USCI_A1 support UART, LIN, IrDA, and SPI; USCI_B0 and USCI_B1 support I²C and SPI. All modules operate independently - enabling simultaneous UART telemetry, I²C sensor reads, and SPI display updates without software arbitration.
What is the operating temperature range specified for the MSP430F2418TPMR?
The MSP430F2418TPMR is rated for industrial temperature operation from –40°C to +85°C. This range is validated across all electrical specifications including supply current, ADC linearity, DCO frequency stability, and I/O drive strength - ensuring reliable performance in outdoor metering, factory-floor controls, and portable medical equipment.
