Product details
Overview
MSP430F2419TPM from Texas Instruments is a 16-bit ultra-low-power mixed-signal 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 at 1.8–3.6 V.
For engineers reviewing the MSP430F2419TPM datasheet, MSP430F2419TPM pinout, MSP430F2419TPM application, or MSP430F2419TPM equivalent, key selection criteria include LQFP-64 package compatibility, absence of DAC12/DMA (vs. F261x), 48 I/O count, calibrated DCO wake-up <1 µs, and support for IrDA, LIN, and hardware multiplier functions.
Technical Context
The MSP430F2419TPM implements a 16-bit RISC CPU with constant generators and five low-power modes optimized for extended battery life. Its clock system integrates a calibrated DCO, LFXT1 (32.768 kHz crystal), and VLO oscillator, enabling sub-µs wake-up from LPM3/LPM4.
Peripheral integration includes two independent USCI modules (each configurable as UART, SPI, or I²C), 12-bit ADC12 with internal reference and autoscan, and Timer_B7 with shadow registers for precise PWM and capture timing - all mapped to 48 GPIO pins in the 64-pin LQFP package.
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 applications. |
| Flash / RAM | 120KB + 256B flash memory and 4KB RAM; supports complex firmware with bootloader (BSL) and secure code protection. |
| ADC Resolution | 12-bit ADC12 with 8-channel input, internal reference, sample-and-hold, and autoscan; suitable for precision analog sensing without external components. |
| Timers | 16-bit Timer_A3 (3 capture/compare registers) and Timer_B7 (7 capture/compare registers with shadow registers); enables multi-channel PWM, input capture, and real-time event sequencing. |
| Communication | Four USCI modules: USCI_A0/A1 (UART/LIN/IrDA/SPI) and USCI_B0/B1 (I²C/SPI); provides flexible serial connectivity with hardware auto-baud detection and synchronous protocol support. |
| Supply Range | 1.8 V to 3.6 V operation; allows direct interface with common Li-ion, coin-cell, and regulated 3.3 V supplies. |
| Low-Power Modes | Active mode: 365 µA @ 1 MHz, 2.2 V; Standby (VLO): 0.5 µA; Off (RAM retention): 0.1 µA - critical for multi-year battery life in remote sensors. |
Pinout & Package
The MSP430F2419TPM is housed in a 64-pin LQFP (10 mm × 10 mm) package with 48 general-purpose I/O pins, JTAG debug interface (TCK/TMS/TDI/TDO), and dedicated analog/digital supply rails (DVCC1/DVSS1, AVCC/AVSS).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RST/NMI | Reset / Non-maskable interrupt input | Active-low reset with programmable NMI edge detection; essential for safe power-on initialization and fault recovery. |
| TCK, TMS, TDI, TDO | JTAG test access port | Enables full-speed in-circuit debugging, flash programming, and boundary-scan testing without external hardware programmers. |
| P1.0–P1.7, P2.0–P2.7, P3.0–P3.7, P4.0–P4.7, P5.0–P5.7, P6.0–P6.7, P7.0–P7.7, P8.0–P8.7 | Configurable GPIO / peripheral multiplexing | 48 total I/O pins with interrupt capability, supporting timer capture, ADC inputs, USCI signals, and digital I/O - mapped per functional block diagram Figure 4-2. |
| XIN / XOUT | LFXT1 crystal oscillator terminals | Supports 32.768 kHz watch crystal for real-time clock (RTC) and low-frequency timing; required for accurate timekeeping in standby mode. |
| VREF+, VREF−, VeREF+ | ADC reference voltage inputs | Accept internal or external reference sources; VeREF+ can be driven by internal bandgap or external DAC output for ratiometric measurements. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low-power active mode | 365 µA @ 1 MHz, 2.2 V - reduces battery drain in always-on sensor nodes and extends operational lifetime. |
| Sub-microsecond wake-up | <1 µs from LPM3/LPM4 to active mode using calibrated DCO - enables rapid response to external interrupts while minimizing sleep current. |
| Integrated hardware multiplier | MPY/MPYS/MAC/MACS instructions accelerate math-intensive tasks (e.g., FIR filtering, sensor fusion) without CPU overhead. |
| Dual USCI modules per interface type | USCI_A0/A1 and USCI_B0/B1 allow concurrent UART + I²C or dual SPI buses - simplifies communication with multiple peripherals (e.g., display + sensor + host MCU). |
| On-chip comparator | Comp_A+ with 8 selectable inputs supports windowed voltage monitoring, battery level detection, and analog threshold triggering without ADC conversion latency. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F2418TPM | 116KB+256B flash, 8KB RAM, identical peripheral set and pinout | Higher RAM supports larger buffers for communication stacks or FFT-based analysis | Select when firmware complexity or real-time data buffering exceeds 4KB RAM capacity. |
| MSP430F2619TPM | Same flash/RAM, but adds DAC12 (dual 12-bit voltage-output DAC) and 3-channel DMA | Required for closed-loop analog control (e.g., sensor excitation, calibration offset correction) | Choose only if DAC or DMA functionality is mandatory; otherwise MSP430F2419TPM offers cost and power advantage. |
Compared with MSP430F2418TPM, the MSP430F2419TPM trades RAM for flash capacity - beneficial for feature-rich firmware with minimal runtime data. Against MSP430F2619TPM, it omits DAC12/DMA to reduce active current and BOM cost, making it optimal for pure sensing and communication roles.

FAQ
What is the maximum ADC sampling rate supported by the MSP430F2419TPM?
The MSP430F2419TPM ADC12 module supports up to 200 kSPS with fADC12CLK ≤ 7 MHz. Conversion time is 1.86 µs minimum (12-bit, no oversampling), achievable using internal DCO or external clock source - verified in Section 8.46 of SLAS541M.
Does the MSP430F2419TPM support hardware UART autobaud detection?
Yes, the MSP430F2419TPM USCI_A modules (USCI_A0 and USCI_A1) include enhanced UART mode with automatic baud-rate detection, allowing reliable communication with hosts transmitting at unknown rates - confirmed in the Features section and Section 8.37 of the datasheet.
Is the MSP430F2419TPM pin-compatible with the MSP430F2619TPM in the LQFP-64 package?
No - while both share the same 64-pin LQFP footprint, MSP430F2419TPM lacks DAC12 and DMA peripherals, resulting in different pin functions for P6.5, P6.6, P6.7, and P2.6 (no DAC0/DAC1/VeREF+/DMAE0). Pin mapping must be validated against Figures 7-2 and 7-4.
What is the operating temperature range for the MSP430F2419TPM?
The MSP430F2419TPM is rated for industrial temperature range: –40°C to +85°C. This is consistent across all "T" version MSP430F2xx devices, as confirmed in Section 8.3 (Recommended Operating Conditions) of SLAS541M.
Can the MSP430F2419TPM drive an external 4-MHz crystal on XT2 pins?
No - the MSP430F2419TPM does not implement the XT2 high-frequency oscillator circuit. Only MSP430F261x variants support XT2 (up to 16 MHz); the F241x series is limited to LFXT1 (≤1 MHz) and internal DCO/VLO - per Section 3 description and functional block diagrams.
