Texas Instruments MSP430F2618TPMR-NM

Overview

MSP430F2618TPMR-NM from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller with 116KB+256B flash, 8KB RAM, dual 12-bit DACs, three-channel DMA, 12-bit ADC with autoscan, two 16-bit timers (Timer_A3 and Timer_B7), four USCI modules (dual UART/IrDA/SPI + dual I²C/SPI), and on-chip comparator. It operates from 1.8 V to 3.6 V and supports wake-up from standby in <1 µs - used in portable medical imaging systems requiring low-noise analog signal generation and precise timing control.

For engineers reviewing the MSP430F2618TPMR-NM datasheet, MSP430F2618TPMR-NM pinout, MSP430F2618TPMR-NM application, or MSP430F2618TPMR-NM equivalent, key selection considerations include its 64-pin LQFP nonmagnetic package, DAC12/DMA support (distinguishing it from F241x), calibrated DCO accuracy over temperature, and integrated SVS/SVM for robust power monitoring in battery-powered sensor nodes.

Technical Context

The MSP430F2618TPMR-NM implements a 16-bit CPU with constant generators and 16-bit registers optimized for code efficiency in ultra-low-power measurement applications. Its five low-power modes leverage the calibrated digitally controlled oscillator (DCO) to achieve sub-1 µs wake-up latency from LPM3/LPM4.

It integrates dual 12-bit voltage-output DACs with synchronization capability, a 12-bit ADC with internal reference and sample-and-hold, and four USCI modules supporting simultaneous UART/IrDA/SPI and I²C protocols - enabling concurrent serial communication and precision analog stimulus/response in compact embedded systems.

FAQ

What is the operating voltage range of the MSP430F2618TPMR-NM?

The MSP430F2618TPMR-NM operates from 1.8 V to 3.6 V. This wide supply range supports direct connection to single-cell Li-ion, Li-polymer, or alkaline battery sources without intermediate regulation - critical for minimizing power loss in energy-constrained designs. The device's SVS and SVM circuits remain functional across this entire range, enabling reliable brownout detection and supply monitoring.

Does the MSP430F2618TPMR-NM support hardware DMA?

Yes, the MSP430F2618TPMR-NM includes a three-channel internal DMA controller. This feature is exclusive to the F261x series and absent in F241x variants. It enables autonomous data movement between peripherals (e.g., ADC12 → RAM, USCI_B0 → RAM) and memory without CPU intervention - reducing active-mode current and improving real-time determinism in MSP430F2618TPMR-NM-based systems.

What distinguishes the 'NM' suffix in MSP430F2618TPMR-NM?

The '-NM' suffix denotes a nonmagnetic 64-pin LQFP (PM) package variant. Unlike standard PM packages, MSP430F2618TPMR-NM uses non-ferrous leadframe and mold compound to meet ASTM F2503 MRI compatibility requirements. This makes it suitable for use inside or near MRI scanner rooms where magnetic interference must be avoided - a requirement not met by standard MSP430F2618TPMR parts.

Can the MSP430F2618TPMR-NM generate synchronized analog outputs?

Yes, the MSP430F2618TPMR-NM integrates two 12-bit DACs (DAC0 and DAC1) with hardware synchronization capability. Both DACs share a common reference (VeREF+) and can be updated simultaneously via a single register write, ensuring phase-aligned analog outputs - essential for differential signaling, balanced sensor excitation, or dual-channel waveform generation in MSP430F2618TPMR-NM applications.

How many USCI modules does the MSP430F2618TPMR-NM include, and what protocols do they support?

The MSP430F2618TPMR-NM includes four USCI modules: USCI_A0 and USCI_A1 support UART, IrDA, and SPI; USCI_B0 and USCI_B1 support I²C and SPI. This allows concurrent operation - for example, UART debug interface (A0), IrDA remote control (A1), I²C temperature sensor bus (B0), and SPI OLED display (B1) - all managed independently without CPU scheduling overhead in MSP430F2618TPMR-NM firmware.
