Product details
Overview
MSP430F5519IPNR from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller with integrated USB 2.0 PHY, four 16-bit timers (TA0/TA1/TA2/TB0), two USCI modules (UART/IrDA/SPI/I²C), RTC, hardware multiplier, and 3-channel DMA. It features 128 KB Flash, 8 KB + 2 KB RAM, 63 I/O pins, and operates from 1.8 V to 3.6 V. It targets USB-connected sensor nodes and portable data loggers requiring fast wake-up and long battery life.
For engineers reviewing the MSP430F5519IPNR datasheet, MSP430F5519IPNR pinout, MSP430F5519IPNR application, or MSP430F5519IPNR equivalent, key selection criteria include USB 2.0 integration, LPM3 current of 1.9 µA at 3.0 V, 3.5 µs wake-up time, 63-pin LQFP package, and absence of integrated ADC (unlike F552x variants).
Technical Context
The MSP430F5519IPNR implements a unified clock system with FLL stabilization, dual crystal support (XT1 for 32-kHz RTC, XT2 up to 32 MHz), and internal VLO/REFO sources. Its power management includes a programmable LDO core regulator, supply voltage supervision (SVM/SVS), and five low-power modes (LPM0–LPM4.5) with full RAM retention in LPM3/LPM4.
Peripherals are mapped via port mapping control registers (PMM), enabling flexible signal routing across 63 GPIOs. The USB subsystem integrates PHY, 3.3-V/1.8-V power system, and USB-PLL - eliminating external transceivers and voltage regulators required by non-USB MSP430 variants.
Key Specifications

FAQ
What is the maximum system clock frequency supported by the MSP430F5519IPNR?
The MSP430F5519IPNR supports a maximum system clock (MCLK) frequency of 25 MHz, achieved using the FLL with XT2 crystal (up to 32 MHz) or internal DCO. This allows real-time processing of USB transactions, timer events, and sensor data at high throughput while maintaining ultra-low power in active mode (290 µA/MHz at 8 MHz, 3.0 V).
Does the MSP430F5519IPNR include an integrated analog-to-digital converter (ADC)?
No, the MSP430F5519IPNR does not include an integrated ADC. Unlike the MSP430F552x series (e.g., MSP430F5529IPN), the MSP430F551x family (including MSP430F5519IPNR) omits the ADC12_A module. This is confirmed in the device comparison table and functional block diagrams - making MSP430F5519IPNR ideal for digital-only USB applications where external ADCs or sensor ICs handle analog conversion.
What package type and pin count does the MSP430F5519IPNR use?
The MSP430F5519IPNR uses an 80-pin LQFP (PN) package with 12 mm × 12 mm body size and 0.5-mm pitch. It provides 63 general-purpose I/O pins, matching the pinout of MSP430F5529IPN and MSP430F5521IPN - enabling drop-in compatibility in designs where ADC is unused and USB/digital functionality is primary.
How does the USB subsystem of the MSP430F5519IPNR differ from non-USB MSP430 variants?
The MSP430F5519IPNR integrates a full-speed USB 2.0 PHY, dedicated USB 3.3-V and 1.8-V power system, and USB-PLL - eliminating all external USB transceivers, voltage regulators, and clock synthesis components required by non-integrated MSP430 families (e.g., MSP430G or F2xx). This reduces component count by ≥7 parts and simplifies USB compliance testing.
What low-power modes are available on the MSP430F5519IPNR, and what is the lowest current consumption?
The MSP430F5519IPNR supports five low-power modes (LPM0–LPM4.5). The lowest active-retention mode is LPM3 (RTC active, full RAM retention), drawing 1.9 µA at 3.0 V. The deepest state is LPM4.5 (shutdown), consuming 0.18 µA at 3.0 V - enabling years of operation on a CR2032 coin cell in always-on monitoring applications.
