Product details
Overview
MSP430F2619TPM from Texas Instruments is a 16-bit ultra-low-power mixed-signal microcontroller featuring 120KB+256B flash, 4KB RAM, dual 12-bit DACs, 12-bit ADC with autoscan, three-channel DMA, and four USCI modules (2× UART/IrDA/SPI, 2× I²C/SPI). It operates from 1.8 V to 3.6 V and targets battery-powered sensor systems and portable medical instrumentation.
For engineers reviewing the MSP430F2619TPM datasheet, MSP430F2619TPM pinout, MSP430F2619TPM application, or MSP430F2619TPM equivalent, key selection criteria include its LQFP-64 package, 48 GPIOs, calibrated DCO wake-up <1 µs from LPM4, integrated SVS/SVM, and dual DAC synchronization-critical for precision analog control in space-constrained embedded designs.
Technical Context
The MSP430F2619TPM implements a 16-bit RISC CPU with constant generators and a 16-MHz DCO clock source, supporting five low-power modes optimized for extended battery life. Its peripheral set includes Timer_A3 (3 capture/compare), Timer_B7 (7 registers with shadow), and hardware multiplier for efficient signal processing.
It integrates two independent 12-bit DACs with voltage output and synchronized update capability, plus an 8-channel 12-bit ADC with internal reference and sample-and-hold-enabling simultaneous analog stimulus generation and acquisition in closed-loop sensor interfaces without external components.

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 |
|---|---|---|---|
| MSP430F2618TPM | Same package and peripherals, but 8KB RAM and 116KB flash-no DAC12 or DMA differences. | Better suited for applications requiring larger RAM buffers (e.g., FFT-based spectral analysis). | Select MSP430F2618TPM when firmware complexity demands >4KB RAM; otherwise MSP430F2619TPM offers optimal flash/RAM balance. |
| MSP430F2419TPM | Identical flash/RAM and pinout, but lacks DAC12 and DMA modules-otherwise identical peripheral set. | Appropriate for cost-sensitive sensor nodes where DAC or DMA functionality is unnecessary. | Choose MSP430F2419TPM only if DAC and DMA are unused; MSP430F2619TPM provides full feature set without layout change. |
Compared with MSP430F2419TPM, the MSP430F2619TPM adds dual 12-bit DACs and three-channel DMA-enabling closed-loop analog control and autonomous data movement-while MSP430F2618TPM trades flash capacity for double RAM, making it preferable for intensive signal buffering over precision analog generation.

FAQ
What is the maximum operating frequency of the MSP430F2619TPM's DCO oscillator?
The MSP430F2619TPM features a calibrated digitally controlled oscillator (DCO) with a maximum frequency of 16 MHz. This DCO supports all active-mode operations and enables wake-up from LPM4 in less than 1 µs. The DCO's frequency tolerance is ±3% over temperature (0°C to 85°C) and ±1.5% over supply voltage (1.8 V to 3.6 V), as specified in the SLAS541M datasheet. MSP430F2619TPM uses this DCO as its primary clock source unless configured for external crystal operation.
Does the MSP430F2619TPM support hardware-accelerated multiplication?
Yes, the MSP430F2619TPM includes a dedicated 16-bit hardware multiplier module supporting MPY, MPYS, MAC, and MACS instructions. This unit executes signed/unsigned multiply and multiply-accumulate operations in a single cycle, significantly accelerating digital filtering, sensor calibration, and mathematical computations. The multiplier is fully integrated into the CPU pipeline and accessible via standard assembly or C compiler intrinsics-no external co-processor is required for performance-critical math in MSP430F2619TPM-based designs.
How many analog input channels does the MSP430F2619TPM ADC support?
The MSP430F2619TPM integrates a 12-bit ADC12 module with 8 selectable analog input channels (A0–A7), configurable via the ADC12CTL0 and ADC12MCTLx registers. These channels map to pins P6.0 through P6.7, with additional flexibility: P6.5, P6.6, and P6.7 serve dual roles as DAC outputs or ADC inputs. The ADC supports internal reference (2.5 V), external reference, sample-and-hold, and autoscan mode-allowing sequential conversion of up to 8 channels without CPU intervention. MSP430F2619TPM's ADC12CLK can run up to 7 MHz for high-speed sampling.
Is the MSP430F2619TPM pin-compatible with other devices in the MSP430F261x family?
Yes, the MSP430F2619TPM in the 64-pin LQFP (PM) package is pin-compatible with MSP430F2616TPM, MSP430F2617TPM, and MSP430F2618TPM-sharing identical pin assignments, electrical characteristics, and peripheral mappings. This allows firmware reuse and board-level interchangeability within the F261x series. However, it is not pin-compatible with MSP430F241x variants (e.g., MSP430F2419TPM) despite identical packaging, due to functional differences in DAC12 and DMA signal routing on shared pins like P6.5–P6.7. MSP430F2619TPM maintains full compatibility only within its own variant group.
What debug interfaces are supported by the MSP430F2619TPM?
The MSP430F2619TPM supports JTAG debugging via dedicated TCK, TMS, TDI/TCLK, and TDO/TDI pins, compliant with IEEE 1149.1. It also supports Spy-Bi-Wire (2-wire JTAG) for reduced pin count debugging. No SWD or ARM-style debug is supported. The device includes emulation logic for real-time breakpoints, watchpoints, and register visibility. Debug access remains functional even when code protection fuses are unblown; however, once the security fuse is programmed, JTAG access is disabled. MSP430F2619TPM does not require external voltage for programming-serial onboard programming (BSL) works via UART or I²C using only VCC.
