Product details
Overview
MSP430F2419TZQW from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller with 120KB+256B flash, 4KB RAM, 12-bit ADC, dual USCI_A/USCI_B modules (UART/I²C/SPI), 16-bit Timer_A and Timer_B, and on-chip comparator - designed for battery-powered sensor nodes and portable medical devices operating from 1.8 V to 3.6 V.
For engineers reviewing the MSP430F2419TZQW datasheet, MSP430F2419TZQW pinout, MSP430F2419TZQW application, or MSP430F2419TZQW equivalent, key selection criteria include LPM4 current (0.1 µA), wake-up time (<1 µs), ADC12 resolution (12-bit, 8-channel), USCI flexibility (dual UART/I²C/SPI), and MicroStar Junior BGA (113-pin, 7 mm × 7 mm) packaging for space-constrained designs.
Technical Context
The MSP430F2419TZQW implements a 16-bit CPU with constant generators and calibrated DCO enabling sub-1-µs wake-up from LPM4. Its peripheral set excludes DAC12 and DMA (unlike MSP430F261x), retaining full ADC12, two USCI_A and two USCI_B modules, and dual 16-bit timers with capture/compare capability.
It supports multiple clock sources: internal VLO (12 kHz), DCO (up to 16 MHz), LFXT1 (32.768 kHz crystal), and XT2 (4–16 MHz crystal). All USCI modules operate independently with programmable baud rates, and the ADC12 includes internal reference, sample-and-hold, and autoscan - optimized for low-duty-cycle sensing in energy-harvesting systems.
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 | 120KB + 256B flash memory and 4KB RAM - sufficient for complex sensor fusion algorithms and bootloader-resident firmware updates. |
| ADC12 | 12-bit SAR ADC with 8 input channels, internal reference, and autoscan - supports simultaneous multi-sensor acquisition without CPU intervention. |
| USCI Modules | Four USCI peripherals: USCI_A0/A1 (UART/LIN/IrDA/SPI) and USCI_B0/B1 (I²C/SPI) - enables concurrent wired communication with sensors, displays, and host controllers. |
| Low-Power Modes | LPM4 draws only 0.1 µA with RAM retention; wake-up latency <1 µs - extends battery life in intermittent-sampling applications like environmental monitors. |
| Operating Voltage | 1.8 V to 3.6 V supply range - compatible with single-cell Li-ion, Li-polymer, and dual-cell alkaline power sources. |
| Timer Resources | 16-bit Timer_A (3 capture/compare registers) and Timer_B (7 capture/compare registers with shadow registers) - supports precise PWM generation, input capture, and real-time scheduling. |

| USCI_B0/USCI_B1 | I²C/SPI master/slave interfaces | Hardware-accelerated I²C (up to 400 kHz) and SPI (up to 8 MHz) - offloads timing-critical bus management from CPU during sensor data aggregation. |
| ADC12INx | Analog input channels (A0–A7) | Eight dedicated analog inputs with programmable sampling control; supports differential and single-ended modes for precision signal conditioning. |
| XIN/XOUT | LFXT1 crystal oscillator terminals | Supports 32.768-kHz watch crystal for real-time clock functionality with ±20 ppm stability over temperature - critical for time-stamped sensor logging. |
| XT2IN/XT2OUT | XT2 high-frequency crystal oscillator terminals | Enables 4–16 MHz external crystal for precise system clocking in timing-sensitive applications such as synchronized data acquisition. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F2418TZQW | 116KB+256B flash, 8KB RAM, identical peripheral set (no DAC/DMA) | Better suited for applications requiring larger RAM buffer for FFT-based signal analysis or extended protocol stacks | Select when firmware complexity demands >4KB RAM but DAC/DMA are unnecessary. |
| MSP430F2619TZQW | Same flash/RAM, adds DAC12 (2-channel, 12-bit) and 3-channel DMA | Required for closed-loop control (e.g., sensor calibration feedback) or high-throughput ADC streaming to memory | Choose only if DAC or DMA functionality is explicitly needed; otherwise MSP430F2419TZQW offers lower cost and same core performance. |
Compared with MSP430F2418TZQW, the MSP430F2419TZQW trades RAM for flash capacity - favoring feature-rich firmware over large data buffers. Against MSP430F2619TZQW, it omits DAC/DMA to reduce cost and power, making it optimal for pure sensing and communication roles without analog output or burst data movement.

FAQ
What is the maximum ADC12 conversion rate supported by the MSP430F2419TZQW?
The MSP430F2419TZQW supports an ADC12CLK frequency up to 7 MHz, enabling a minimum conversion time of 1.86 µs per sample. This allows sustained sampling rates up to approximately 537 kSPS in single-channel mode, though practical throughput depends on channel count, reference selection, and software overhead. The MSP430F2419TZQW datasheet specifies tCONVERT MIN = 1.86 µs under recommended operating conditions.
Does the MSP430F2419TZQW include a hardware multiplier?
Yes, the MSP430F2419TZQW includes a 16-bit hardware multiplier unit (MPY, MPYS, MAC, MACS) capable of completing multiply operations in one CPU cycle. This accelerates fixed-point arithmetic used in digital filtering, sensor linearization, and control loop calculations - reducing active-mode execution time and overall energy consumption in the MSP430F2419TZQW.
Is the MSP430F2419TZQW pin-compatible with other packages in the MSP430F241x family?
No, the MSP430F2419TZQW uses the MicroStar Junior BGA (113-ball) package, which is not pin-compatible with the 64-pin PM or 80-pin PN LQFP variants. While functional peripheral mapping is consistent across the family, ball assignments, power/ground distribution, and thermal pad configuration differ. Migration requires PCB redesign; refer to TI's SLAS541M pin diagrams for exact ZQW terminal layout.
Can the MSP430F2419TZQW operate without an external crystal?
Yes, the MSP430F2419TZQW can operate using its internal digitally controlled oscillator (DCO) calibrated to ±3% accuracy over voltage and temperature, or the internal VLO (12 kHz) for ultra-low-power real-time clock functions. External crystals (LFXT1 or XT2) are optional and used only when higher timing precision is required - the MSP430F2419TZQW remains fully functional without them.
What debug interface does the MSP430F2419TZQW support?
The MSP430F2419TZQW supports standard 4-wire JTAG (TCK, TMS, TDI, TDO) for full-speed emulation, flash programming, and real-time debugging. It also supports Spy-Bi-Wire (SBW), a 2-wire variant using TCK and TMS only, which conserves board space. Both interfaces are accessible through the MicroStar Junior BGA package's dedicated debug balls - no external voltage is needed for programming the MSP430F2419TZQW.
