Product details
Overview
MSP430F2619TPMR from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller with 120KB+256B flash, 4KB RAM, dual 12-bit DACs, 12-bit ADC, three-channel DMA, and four USCI modules (dual UART/IrDA/SPI + dual I²C/SPI). It operates from 1.8 V to 3.6 V and supports wake-up from standby in <1 µs - deployed in portable medical imaging and industrial sensor nodes requiring long battery life and mixed-signal precision.
For engineers reviewing the MSP430F2619TPMR datasheet, MSP430F2619TPMR pinout, MSP430F2619TPMR application, or MSP430F2619TPMR equivalent, key selection criteria include its 64-pin LQFP package, integrated DAC12/DMA support (distinguishing it from F241x), calibrated DCO for fast wake-up, and nonmagnetic option suitability for MRI-adjacent systems.
Technical Context
The MSP430F2619TPMR implements a 16-bit CPU with constant generators and a 16-MHz DCO clock source, enabling 62.5-ns instruction cycles. Its peripheral set includes Timer_A3 (3 capture/compare), Timer_B7 (7 capture/compare with shadow registers), and dual USCI_A/USCI_B modules supporting simultaneous UART, IrDA, SPI, and I²C protocols.
It integrates analog functions including an 8-channel 12-bit ADC with internal reference and autoscan, an 8-channel comparator, and two synchronized 12-bit voltage-output DACs - all accessible via DMA channels for autonomous data flow without CPU intervention in low-power modes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | 16-bit RISC CPU with 16 registers and constant generators; enables high code efficiency in memory-constrained embedded firmware. |
| Flash / RAM | 120KB + 256B flash memory and 4KB RAM; sufficient for complex sensor fusion algorithms and bootloader-resident field updates. |
| ADC | 12-bit SAR ADC with 8 input channels, internal reference, sample-and-hold, and autoscan; supports precise multi-sensor acquisition at up to 7 MHz conversion clock. |
| DAC | Dual 12-bit voltage-output DACs with synchronization; enables simultaneous analog stimulus generation (e.g., bias control + calibration signal) in closed-loop systems. |
| DMA | Three-channel DMA controller; permits autonomous movement of ADC results, DAC data, or USCI buffers - critical for LPM3/LPM4 operation with zero CPU wake-ups. |
| Low-Power Modes | Active mode: 365 µA @ 1 MHz / 2.2 V; Standby (VLO): 0.5 µA; Off (RAM retention): 0.1 µA - optimized for >10-year coin-cell operation in remote sensors. |
| Wake-up Time | <1 µs from standby to active mode; ensures deterministic real-time response to external interrupts (e.g., emergency sensor threshold breach). |
Pinout & Package
The MSP430F2619TPMR is packaged in a 64-pin LQFP (PM) with 10 mm × 10 mm body size and standard 0.5 mm pitch. Pin functions are validated per TI SLAS541M Figure 7-4 and Table 9-19–9-27.
| Pin/Terminal | Circuit Role | Design Meaning |

| TCK/TMS/TDI/TDO | JTAG emulation interface | Full boundary-scan debug and flash programming without boot ROM dependency; compatible with MSP-FET430UIF and similar tools. |
| P1.0–P1.7, P2.0–P2.7, etc. | Configurable GPIO with interrupt capability | Up to 48 total I/O pins across P1–P8 ports; each supports edge-selectable interrupts, pullup/pulldown, and peripheral multiplexing (e.g., TA0, CAOUT, UCA0TXD). |
| UCA0TXD/UCA0RXD, UCB0SIMO/UCB0SOMI | USCI_A0 (UART/SPI) and USCI_B0 (SPI/I²C) signals | Dual independent serial interfaces enable concurrent host communication (UART) and sensor bus control (I²C) without software arbitration. |
| DAC0/DAC1 output pins (P6.6/P6.5) | Analog voltage outputs | Dedicated DAC output terminals with rail-to-rail swing; used for programmable biasing, waveform synthesis, or feedback loop injection. |
Key Features
| Feature | Design Value |
|---|---|
| Calibrated DCO oscillator | Enables sub-1-µs wake-up from LPM3/LPM4 with ±3% frequency tolerance over 0°C–85°C and full VCC range - eliminates need for external crystal in cost-sensitive designs. |
| Integrated supply monitoring | Programmable SVS/SVM with multiple threshold levels protects firmware integrity during brownout events and enables graceful shutdown in battery-powered systems. |
| Bootloader (BSL) | ROM-resident UART-based bootloader allows field firmware updates without JTAG hardware - reduces service cost and enables remote device reprogramming. |
| Nonmagnetic LQFP option | The PM package variant is certified nonmagnetic per ASTM F2503; qualified for use in MRI-adjacent medical imaging equipment where magnetic interference must be avoided. |

Applications
| Portable Medical Imaging Sensors | Industrial Process Monitoring Nodes |
|---|---|
Use Scenario: Compact MRI-compatible temperature and pressure sensors mounted near scanner gantry for real-time thermal drift compensation. IC Role / Device Role / Timing Role: MSP430F2619TPMR acts as the primary sensor hub MCU - acquiring analog inputs via ADC12, generating bias voltages via DAC12, and transmitting time-stamped data over UART to host PC. Use Value: Nonmagnetic 64-pin LQFP package avoids magnetic distortion; ultra-low standby current (0.5 µA) extends battery life beyond 5 years; <1 µs wake-up ensures immediate response to thermal anomaly triggers. | Use Scenario: Wireless vibration and current monitoring node on rotating machinery in factory automation, powered by energy harvesting. IC Role / Device Role / Timing Role: MSP430F2619TPMR serves as the low-power data concentrator - sampling accelerometer and shunt voltage via ADC12, performing FFT preprocessing using hardware MAC, and transmitting results via USCI_A1 UART to LoRaWAN gateway. Use Value: Three-channel DMA offloads CPU during burst acquisition; dual USCI modules allow simultaneous sensor bus (I²C) and radio interface (UART); 0.1 µA off-mode preserves state during intermittent energy availability. |
| Hand-Held Diagnostic Meters | Environmental Data Loggers |
Use Scenario: Battery-operated handheld multimeter with analog front-end, LCD driver, and USB/UART connectivity for lab-grade measurements. IC Role / Device Role / Timing Role: MSP430F2619TPMR executes metrology firmware - controlling 12-bit ADC sampling sequence, managing dual DAC references for auto-zeroing, and driving segment LCD via integrated peripherals. Use Value: Integrated comparator and DAC12 eliminate external calibration ICs; 120KB flash accommodates metrology libraries and self-test routines; BSL enables post-deployment calibration updates via USB-UART bridge. | Use Scenario: Solar-powered outdoor air quality logger measuring PM2.5, NO₂, and humidity across seasonal temperature ranges (−40°C to +85°C). IC Role / Device Role / Timing Role: MSP430F2619TPMR functions as the system orchestrator - sequencing multi-sensor reads, compensating for temperature drift using internal sensor and DAC outputs, and storing timestamped data in flash. Use Value: Calibrated DCO maintains timing accuracy across temperature extremes; SVS/SVM prevents corruption during solar panel voltage sag; 4KB RAM buffers extended logging intervals before flash write. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power mixed-signal microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F2618TPMR | Same 64-pin LQFP package, but with 8KB RAM and 116KB flash - no change in peripheral set or DAC/DMA capability. | Better suited for applications requiring larger firmware image or extended RAM buffers (e.g., protocol stacks with TLS handshake). | Select MSP430F2618TPMR when firmware complexity or real-time data buffering demands >4KB RAM; otherwise MSP430F2619TPMR offers optimal flash/RAM balance for most sensor hubs. |
| MSP430F2419TPMR | Identical flash/RAM (120KB/4KB) and pinout, but lacks DAC12 and DMA modules - otherwise shares same timers, ADC, USCI, and low-power architecture. | Appropriate for cost-sensitive applications needing only ADC and serial comms - not viable where DAC-driven calibration or autonomous DMA transfers are required. | Choose MSP430F2419TPMR only if DAC and DMA are unused; MSP430F2619TPMR provides essential analog stimulus and data movement capability without layout change. |
Compared with MSP430F2618TPMR and MSP430F2419TPMR, the MSP430F2619TPMR delivers the highest flash capacity (120KB) within the 4KB RAM configuration, while retaining full DAC12 and DMA functionality - making it the most capable variant for precision analog-intensive, battery-constrained designs without increasing PCB footprint.
