Product details
Overview
MSP430F2419TPMR from Texas Instruments is a 16-bit ultra-low-power mixed-signal microcontroller featuring 120KB+256B flash, 4KB RAM, 12-bit ADC with autoscan, dual USCI_A/USCI_B modules (UART/I²C/SPI), and two 16-bit timers (Timer_A3 and Timer_B7). It operates from 1.8 V to 3.6 V and targets battery-powered sensor nodes and portable medical devices requiring sub-1µs wake-up and <0.1 µA off-mode retention.
For engineers reviewing the MSP430F2419TPMR datasheet, MSP430F2419TPMR pinout, MSP430F2419TPMR application, or MSP430F2419TPMR equivalent, key selection criteria include its LQFP-64 package, absence of DAC12 and DMA (distinguishing it from F261x), calibrated DCO for fast wake-up, and support for IrDA, LIN, and hardware multiplier - all critical for low-power embedded control in constrained environments.
Technical Context
The MSP430F2419TPMR implements a 16-bit RISC CPU with constant generators and five low-power modes, optimized for extended battery life in portable measurement systems. Its architecture integrates a 12-bit ADC12 with internal reference and sample-and-hold, plus two independent USCI modules enabling simultaneous UART and I²C communication.
It uses a calibrated digitally controlled oscillator (DCO) that achieves active-mode wake-up in under 1 µs from LPM3/LPM4, and supports external crystal oscillators (LFXT1 for 32.768 kHz, XT2 for up to 16 MHz). The device lacks DAC12 and DMA peripherals - confirmed exclusions versus MSP430F261x family members.

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 |
|---|---|---|---|
| MSP430F2418TPMR | 116 KB + 256 B flash, 8 KB RAM; identical peripheral set and pinout. | Higher RAM supports larger buffers for continuous data logging or protocol stacks. | Select when firmware complexity or real-time buffering demands >4 KB RAM; otherwise, MSP430F2419TPMR offers optimal flash/RAM balance. |
| MSP430F2619TPMR | Includes DAC12 (2×12-bit voltage-output) and 3-channel DMA; same flash/RAM and package. | DAC enables analog waveform generation (e.g., sensor excitation); DMA reduces CPU load during ADC/USCI transfers. | Choose only if DAC or DMA functionality is required; MSP430F2419TPMR provides cost and power advantage where those features are unused. |
Compared with MSP430F2418TPMR, MSP430F2419TPMR trades 4 KB RAM for 4 KB flash - beneficial for feature-rich firmware with minimal runtime data; versus MSP430F2619TPMR, it removes DAC/DMA to reduce leakage and BOM cost while retaining identical timing, communication, and sensing capabilities.

FAQ
What is the maximum operating frequency of the MSP430F2419TPMR?
The MSP430F2419TPMR supports a maximum system clock of 16 MHz using the XT2 oscillator. Its calibrated DCO delivers up to 16 MHz internally without external components, and the CPU executes instructions at 62.5 ns per cycle (16 MIPS) - verified in Section 8.19 and Figure 8-24 of the SLAS541M datasheet.
Does the MSP430F2419TPMR include a DAC or DMA controller?
No, the MSP430F2419TPMR does not include DAC12 or DMA peripherals. These modules are exclusive to the MSP430F261x series. The MSP430F2419TPMR retains all other core peripherals - including ADC12, Timer_A3, Timer_B7, USCI_A0/A1/B0/B1, and comparator - as confirmed in Section 1 and Table 6-1 of the SLAS541M datasheet.
Which packages are available for the MSP430F2419TPMR?
The MSP430F2419TPMR is offered exclusively in the 64-pin LQFP (PM) package, measuring 10 mm × 10 mm. While the broader MSP430F241x family includes 80-pin LQFP (PN) and 113-pin nFBGA (ZCA/ZQW) variants, the 'TPMR' suffix specifically denotes the PM package - per TI's Package Option Addendum and Device Information table in SLAS541M.
What is the ADC resolution and channel count of the MSP430F2419TPMR?
The MSP430F2419TPMR integrates a 12-bit successive-approximation ADC (ADC12) with 8 input channels, internal reference, sample-and-hold, and autoscan capability. It supports up to 7 MHz ADC clock (fADC12CLK) and achieves 1.86 µs minimum conversion time - specifications validated in Sections 8.43–8.47 of the SLAS541M datasheet.
How does the MSP430F2419TPMR achieve ultra-low-power operation?
The MSP430F2419TPMR achieves ultra-low-power operation through five configurable low-power modes (LPM0–LPM4), a 0.1 µA off-mode with RAM retention, 0.5 µA standby with VLO, and active-mode current of 365 µA at 1 MHz/2.2 V. Its architecture minimizes switching activity via gated clocks and peripheral-specific enable controls - detailed in Sections 3, 8.6, and 9.3 of SLAS541M.
