Texas Instruments MSP430F2619SPM

Overview

MSP430F2619SPM from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller with 120 KB Flash, 4 KB RAM, dual 12-bit DACs, a 12-bit ADC with internal reference and autoscan, three-channel DMA, four USCI modules (UART/LIN/IrDA/SPI/I²C), two 16-bit timers (Timer_A3 and Timer_B7), and on-chip comparator-designed for extreme-temperature sensor systems and standalone RF front ends operating from –55°C to +150°C.

For engineers reviewing the MSP430F2619SPM datasheet, MSP430F2619SPM pinout, MSP430F2619SPM application, or MSP430F2619SPM equivalent, key selection criteria include its high-temperature qualification (1000 hrs at max rated temperature), QFP-64 package with verified pin mapping, integrated SVS/Brownout protection, and support for LIN auto-baud detection and synchronized dual DAC output in harsh-environment embedded control.

Technical Context

The MSP430F2619SPM implements a 16-bit CPU with constant generators and a digitally controlled oscillator (DCO) enabling sub-1-μs wake-up from Standby mode. Its five low-power modes-including LPM4 (0.1 μA RAM retention) and LPM3 (0.5 μA VLO)-are optimized for battery-powered measurement applications requiring long operational life.

Peripherals are tightly integrated via shared memory-mapped registers and hardware-triggered DMA channels. The ADC12 supports up to 8 analog inputs with sample-and-hold and internal/external reference selection, while DAC12 provides two synchronized 12-bit voltage outputs with dedicated pins (P6.5/DAC1, P6.6/DAC0, P6.7/DAC1/SVSIN) and programmable reference sourcing.

FAQ

What is the maximum operating temperature specification for the MSP430F2619SPM?

The MSP430F2619SPM is qualified for continuous operation from –55°C to +150°C and has been tested for 1000 hours at maximum rated temperature. This high-temperature rating is achieved through TI's controlled baseline process, extended product lifecycle management, and full traceability - making MSP430F2619SPM suitable for downhole, aerospace, and under-hood automotive applications where standard MCUs fail.

Does the MSP430F2619SPM support LIN bus communication?

Yes, the MSP430F2619SPM supports LIN bus communication via its USCI_A0 and USCI_A1 modules, which include enhanced UART with auto-baud-rate detection - a mandatory feature for LIN 2.x slave node implementation. The MSP430F2619SPM can serve as a LIN slave controlling actuators or reporting sensor data without external transceivers when paired with TI's SN65HV23x series.

How many analog input channels does the ADC12 module support on the MSP430F2619SPM?

The ADC12 module on the MSP430F2619SPM supports up to eight analog input channels (A0–A7), accessible via P6.0 through P6.7. It includes internal reference (2.5 V), sample-and-hold, and autoscan functionality - allowing sequential conversion of multiple sensors without CPU intervention, directly leveraging the three-channel DMA for efficient data transfer.

What are the DAC output capabilities of the MSP430F2619SPM?

The MSP430F2619SPM features two synchronized 12-bit voltage-output DACs (DAC12.0 and DAC12.1) with dedicated pins: DAC0 on P6.6, DAC1 on P6.5 and P6.7. Both support internal or external reference sourcing, monotonic output, and ±1 LSB integral nonlinearity - enabling precision analog actuation, calibration offset correction, or waveform generation in closed-loop systems.

Is the MSP430F2619SPM pin-compatible with other MSP430F2xx devices in QFP-64 packages?

The MSP430F2619SPM shares the same 64-pin QFP (PM) mechanical footprint and core peripheral mapping with other MSP430F2xx variants like MSP430F2419TPM, but functional pin assignments differ for certain USCI and timer signals. While PCB layout is mechanically compatible, firmware and schematic validation are required due to variations in peripheral routing - e.g., P5.7 serves as TBOUTH/SVSOUT on MSP430F2619SPM but differs on lower-pin-count derivatives.
