Texas Instruments MSP430F2419TPNR

Overview

MSP430F2419TPNR from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller featuring 120KB+256B flash, 4KB RAM, 12-bit ADC with sample-and-hold and autoscan, dual 16-bit timers (Timer_A3 and Timer_B7), four USCI modules (two UART/IrDA/SPI, two SPI/I²C), and on-chip comparator - deployed in battery-powered sensor nodes and portable medical meters.

For engineers reviewing the MSP430F2419TPNR datasheet, MSP430F2419TPNR pinout, MSP430F2419TPNR application, or MSP430F2419TPNR equivalent, key selection criteria include LQFP-64 package compatibility, 1.8–3.6 V supply range, sub-1 µs wake-up from standby, 365 µA active current at 1 MHz/2.2 V, and absence of DAC12/DMA modules versus F261x counterparts.

Technical Context

The MSP430F2419TPNR implements a 16-bit CPU with constant generators and calibrated DCO enabling sub-1 µs wake-up from LPM3/LPM4. Its peripheral set includes ADC12 with internal reference and eight input channels, two independent USCI_A modules supporting UART/LIN/IrDA/SPI, and two USCI_B modules supporting I²C and SPI - all operating under five low-power modes.

Unlike the MSP430F261x series, the MSP430F2419TPNR omits DAC12 and DMA controllers but retains identical timer architecture (Timer_A3 with three capture/compare registers, Timer_B7 with seven plus shadow registers), comparator, and USCI count - making it suitable for cost-optimized, analog-sensing applications without voltage-output DAC or high-bandwidth data movement.

FAQ

What is the maximum operating frequency of the MSP430F2419TPNR?

The MSP430F2419TPNR operates at up to 16 MHz using the internal DCO or external crystals. Its 16-bit RISC core achieves a 62.5-ns instruction cycle time at this rate. The calibrated DCO provides stable operation across voltage and temperature ranges without requiring external components - a key enabler for compact, low-BOM-cost designs using the MSP430F2419TPNR.

Does the MSP430F2419TPNR support hardware UART with automatic baud-rate detection?

Yes, the MSP430F2419TPNR supports enhanced UART mode with automatic baud-rate detection on both USCI_A0 and USCI_A1 modules. This feature allows the MSP430F2419TPNR to synchronize to unknown host UART rates during boot or reconfiguration - simplifying interoperability with legacy or variable-speed peripherals without software polling overhead.

Is the MSP430F2419TPNR pin-compatible with the MSP430F2619TPNR in the LQFP-64 package?

No - although both share the LQFP-64 (PM) package footprint, the MSP430F2419TPNR and MSP430F2619TPNR differ in pin function allocation. For example, P6.5/P6.6/P6.7 on the MSP430F2619TPNR serve DAC1/DAC0/DAC1 respectively, while those pins on the MSP430F2419TPNR are general-purpose analog inputs (A5/A6/A7). Direct replacement requires PCB redesign.

What is the ADC12 conversion time specification for the MSP430F2419TPNR?

The MSP430F2419TPNR ADC12 has a minimum conversion time of 1.86 µs at 7 MHz ADC clock (fADC12CLK). With internal reference enabled and autoscan active, it achieves 12-bit resolution across eight channels - enabling synchronized multi-sensor acquisition critical for applications like impedance spectroscopy or multi-parameter environmental monitoring using the MSP430F2419TPNR.

Does the MSP430F2419TPNR include a hardware multiplier?

Yes, the MSP430F2419TPNR integrates a 16-bit hardware multiplier supporting MPY, MPYS, MAC, and MACS instructions. This unit accelerates fixed-point arithmetic for FIR filtering, RMS calculation, or sensor linearization - reducing CPU load and active-mode duration. Firmware leveraging the hardware multiplier directly improves energy efficiency in signal-processing tasks executed by the MSP430F2419TPNR.
