MSP430F5519IPNR - 25MHz 128KB Flash USB MCU | Texas Instruments
Teilenummer: MSP430F5519IPNR ✓ AktivMSP430F5519IPNR Übersicht
The MSP430 is an ultra-low-power RISC microcontroller family designed around a 16-bit CPU, efficient register architecture, and multiple low-power operating modes. These characteristics make the MSP430F5519 appropriate for battery-powered measurement, communications, industrial control, and portable equipment where energy efficiency is a primary design constraint.
Key features include a 25 MHz CPU, 128KB flash, 8KB SRAM, 63 I/O pins, a comparator, DMA, UART, SPI, I²C, USB, timers, and a hardware multiplier. The integrated connectivity and mixed-signal resources reduce the need for external peripheral devices while providing flexible interface options for sensors, actuators, and communication modules.
The device uses the MSP430 CPUXV2 core, a 16-bit RISC architecture with 16-bit registers and constant generators intended to improve code efficiency. Its operating range of 1.8 V to 3.6 V supports low-voltage embedded designs, while the 80-LQFP package provides a conventional surface-mount footprint with a large number of accessible I/O pins.
Typical applications include USB-connected control systems, low-power data acquisition, industrial instrumentation, sensor networks, portable measurement equipment, and embedded communications products. The combination of USB, UART, SPI, I²C, DMA, timers, comparator, and hardware multiplier allows designers to connect sensors, storage, displays, and host systems without building a complex peripheral network.
When designing around the MSP430F5519IPNR, verify the complete pinout, supply requirements, clock configuration, and peripheral multiplexing against the manufacturer datasheet. Decoupling, USB routing, and low-power mode entry require careful PCB and firmware planning, especially when the system combines USB connectivity with battery-operated operation.

Typische Anwendungen
MSP430F5519IPNR ist geeignet für 6 Anwendungs: USB-connected industrial data acquisition, Low-power sensor network node, Portable medical measurement instrument, Industrial instrument control panel, USB firmware update and configuration device, Embedded communications and protocol bridge.
USB-connected industrial data acquisition
The MSP430F5519IPNR fits USB data-acquisition products because it combines a 25 MHz MSP430F5xx core with 128KB flash, 8KB SRAM, USB, UART, SPI, I²C, and DMA in one 80-LQFP device. Its 1.8 V to 3.6 V supply range supports compact embedded systems, while 63 I/O pins leave flexibility for sensors, status indicators, and control signals. DMA can move sampled data between memory and peripherals, reducing CPU intervention during acquisition. The design must verify USB routing, connector requirements, firmware support, and decoupling on the TI datasheet before layout release.
Empfohlen
Low-power sensor network node
The MSP430F5519IPNR is appropriate for a battery-powered sensor node that needs local control, serial communications, and flexible low-power behavior. The MSP430 architecture is designed for extended battery life in portable measurement applications, and the verified active-current figure is 290 µA/MHz at 8 MHz and 3.0 V. UART, SPI, and I²C allow connection to environmental sensors, radio modules, or local storage, while the comparator can support threshold-based sensing. Actual battery performance depends on the duty cycle, radio states, sensor load, and firmware configuration of the low-power modes.
Empfohlen
Portable medical measurement instrument
The MSP430F5519IPNR can serve as the control core of a portable measurement instrument that combines analog sensing with USB connectivity. Its comparator, timers, DMA, hardware multiplier, and low-voltage operation support measured signal conditioning and control tasks, while the 80-LQFP package exposes a large number of I/O options for sensors and user controls. The 8KB SRAM is suitable for buffering moderate datasets, although larger captures may require external memory. For medical designs, verify isolation, patient-safety requirements, analog accuracy, and regulatory obligations independently of the MCU datasheet.
Empfohlen
Industrial instrument control panel
MSP430F5519IPNR is suitable for industrial control panels requiring several communications paths and a moderate number of I/O pins. UART can support service consoles or external controllers, SPI can connect to displays or storage, and I²C can handle configuration peripherals and sensors. The 1.8 V to 3.6 V operating range and -40°C to +85°C temperature rating align with many embedded industrial environments. Designers should confirm logic levels, isolation, ESD protection, and connector protection according to the final system environment rather than relying only on the MCU specifications.
Empfohlen
USB firmware update and configuration device
The MSP430F5519IPNR can act as a USB-connected configuration controller for a larger embedded product. Its USB interface enables host communication, while 128KB flash provides room for application firmware, update logic, and configuration data. The hardware multiplier and DMA can support protocol processing or background transfers, and the 80-LQFP package offers ample pin access for status LEDs, reset control, and external interface signals. Firmware must include secure update handling where required, and the USB electrical design must follow the relevant device documentation and board-level implementation requirements.
Empfohlen
Embedded communications and protocol bridge
The MSP430F5519IPNR is a strong candidate for a protocol bridge between USB and embedded serial devices because it provides USB, UART, SPI, and I²C in one MCU. The 25 MHz CPU supports moderate protocol processing, while DMA and timers help manage predictable data movement. Eight kilobytes of RAM can support buffering for short frames or command processing, and 128KB flash accommodates firmware tables and bridge logic. The system designer should verify baud-rate tolerance, buffer sizing, flow control, and peripheral multiplexing for the specific bridge protocol before finalizing the design.

Designhinweise
Plan the MSP430F5519IPNR supply for the verified 1.8 V to 3.6 V operating range and place local bypass capacitors close to the device supply pins. USB-connected designs should account for the additional current and voltage behavior of the USB transceiver and follow the TI datasheet's recommended power network. Do not infer USB operating limits from the general MCU supply range alone.
Use the 80-LQFP footprint with careful attention to the exposed power, ground, and alternate-function pins. Keep USB differential routing short, controlled-impedance, and free from unnecessary stubs. For mixed-signal boards, separate sensitive analog inputs from switching and digital return paths, and verify the final pin multiplexing against the device documentation before fabrication.
Do not treat a related MSP430 part as a drop-in replacement merely because it has a similar family name or LQFP package. Verify every pin, alternate function, supply limit, memory size, USB connection, and firmware dependency against the manufacturer datasheet. This is especially important for MSP430F6723IPNR and MSP430F6736IPNR, which appeared in comparison results but were not proven pin-compatible replacements.
The verified distributor listing reports a 1.8 V to 3.6 V range, but not every peripheral mode is guaranteed across that entire range in the supplied data. Confirm clock speed, USB operation, analog comparator behavior, and I/O limits for the intended voltage. Also validate the internal oscillator and clock configuration in the firmware because the listed oscillator type is internal.
Compliance-Informationen
Compliance information was not included in the supplied verified web data or internal database data. Confirm RoHS, REACH, lead-free, halogen-free, and conflict-minerals status using current manufacturer documentation.
