Product details
Overview
MSP430F2419TZQWR 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 systems and portable medical devices operating from 1.8 V to 3.6 V.
For engineers reviewing the MSP430F2419TZQWR datasheet, MSP430F2419TZQWR pinout, MSP430F2419TZQWR application, or MSP430F2419TZQWR equivalent, key selection criteria include LPM4 current (0.1 µA), wake-up time (<1 µs), ADC12 resolution (12-bit, 8-channel), I/O count (48), and MicroStar Junior BGA (113-ball) package compatibility with medical imaging layouts.
Technical Context
The MSP430F2419TZQWR implements a 16-bit CPU with constant generators and calibrated DCO enabling sub-1-µs wake-up from LPM4. Its peripheral set includes ADC12 with internal reference and autoscan, two USCI_A modules supporting UART/LIN/IrDA/SPI, and two USCI_B modules supporting I²C and SPI - all configurable without DMA (not present in F241x series).
Unlike the MSP430F261x family, the MSP430F2419TZQWR omits DAC12 and DMA modules but retains identical Timer_A3, Timer_B7, Comparator_A+, and USCI architecture - making it suitable for measurement applications requiring analog sensing and serial communication without voltage-output DAC or memory-mapped data movement.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F2419TPM | LQFP-64 package (10 mm × 10 mm); same core, flash, RAM, and peripherals as MSP430F2419TZQWR. | Requires PCB redesign for land pattern and thermal relief; better suited for prototyping or non-magnetic medical assemblies. | Select when manual rework, test probe access, or non-BGA assembly is required. |
| MSP430F2619TZQWR | Adds DAC12 (dual 12-bit voltage-output) and 3-channel DMA; otherwise identical package, pinout, and memory configuration. | Enables closed-loop analog control (e.g., sensor calibration offset correction) and burst ADC-to-memory transfers. | Select when DAC or DMA functionality is needed - no PCB change required due to pin-for-pin compatibility. |
Compared with MSP430F2419TPM, the MSP430F2419TZQWR offers higher I/O density and smaller footprint in BGA form, while MSP430F2619TZQWR adds analog output and data movement capability without altering layout - making the latter a drop-in upgrade path for enhanced functionality.

FAQ
What is the maximum ADC12 sampling rate supported by the MSP430F2419TZQWR?
The MSP430F2419TZQWR supports ADC12CLK up to 7 MHz, enabling a minimum conversion time of 1.86 µs per sample (12-bit, single-channel). This yields up to ~537 kSPS in continuous mode with autoscan disabled - sufficient for ultrasound pre-processing and high-resolution thermistor logging.
Does the MSP430F2419TZQWR include a hardware multiplier unit?
Yes, the MSP430F2419TZQWR integrates a 16×16-bit hardware multiplier supporting signed/unsigned multiply and MAC operations. This unit executes in one CPU cycle and is accessible via MPY, MPYS, MAC, and MACS instructions - accelerating FFTs, PID control, and sensor linearization in firmware.
Is the MSP430F2419TZQWR pin-compatible with any MSP430F261x devices?
Yes, the MSP430F2419TZQWR is pin-compatible with the MSP430F2619TZQWR in the ZQW package. Both share identical ball map, power domains, and peripheral pin assignments - differing only in internal DAC12 and DMA module presence, which are disabled or unconnected in the F2419 variant.
What debug interfaces are supported on the MSP430F2419TZQWR?
The MSP430F2419TZQWR supports full-speed JTAG (TCK/TMS/TDI/TDO) for emulation and programming, plus ROM-based UART bootloader (BSL) accessible via USCI_A0. No SWD or cJTAG is implemented - JTAG remains the primary debug and production programming interface.
What is the qualified temperature range for the MSP430F2419TZQWR?
The MSP430F2419TZQWR is specified for operation from –40°C to 85°C (industrial temperature grade). All electrical characteristics - including DCO accuracy, ADC linearity, and LPM4 current - are guaranteed across this full range per TI SLAS541M Section 8.
