Product details
Overview
MSP430F5419AIPZR from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller with 128 KB flash, 16 KB RAM, 12-bit ADC (14 external + 2 internal channels), three 16-bit timers (TA0/TA1/TB0), four USCI modules (2 UART/IrDA/SPI + 2 I²C/SPI), RTC, hardware multiplier, and DMA. It operates from 1.8 V to 3.6 V and targets battery-powered sensor systems and portable instrumentation.
For engineers reviewing the MSP430F5419AIPZR datasheet, MSP430F5419AIPZR pinout, MSP430F5419AIPZR application, or MSP430F5419AIPZR equivalent, key selection criteria include LPM3 standby current (1.7 µA), 3.5-µs wakeup time, 100-pin LQFP package compatibility, and integrated low-power clock system with FLL, REFO, and VLO.
Technical Context
The MSP430F5419AIPZR implements a CPUXV2 core with constant generators for optimized code density and executes instructions at up to 25 MHz. Its unified clock system integrates FLL-based frequency stabilization, dual crystal support (32 kHz XT1 and up to 32 MHz XT2), and low-power internal sources (VLO, REFO).
Power management includes a fully integrated LDO with programmable core voltage, supply supervision (SVM/SVS), brownout detection, and five low-power modes (LPM0–LPM4.5). Peripheral integration features 87 GPIOs, 3-channel DMA, and RTC with alarm capability - all designed for deterministic real-time operation in energy-constrained environments.

FAQ
What is the maximum operating frequency of the MSP430F5419AIPZR?
The MSP430F5419AIPZR supports a maximum system clock frequency of 25 MHz, achieved using the integrated FLL with external high-frequency crystal (up to 32 MHz) or internal DCO calibration. This allows real-time execution of complex sensor processing tasks while maintaining ultra-low power consumption in active mode.
Does the MSP430F5419AIPZR include an integrated real-time clock (RTC)?
Yes, the MSP430F5419AIPZR includes a dedicated RTC_A module with calendar functionality and alarm capability. It operates in LPM3 with a 32-kHz crystal connected to P7.0/XIN and P7.1/XOUT, drawing only 1.7 µA at 3.0 V - enabling accurate timekeeping during extended low-power operation.
How many analog input channels does the 12-bit ADC support on the MSP430F5419AIPZR?
The MSP430F5419AIPZR's ADC12_A module supports 16 total input channels: 14 external analog inputs (A0–A15, mapped across ports P5–P7) and 2 internal channels (temperature sensor and VCC/2 reference). Autoscan mode allows automatic sequential conversion without CPU intervention.
What debug interface does the MSP430F5419AIPZR support?
The MSP430F5419AIPZR supports both JTAG and 2-wire Spy-Bi-Wire (SBW) interfaces via pins PJ.0–PJ.3 and RST/NMI/SBWTDIO. SBW enables full debugging and programming using only two pins, reducing test point count and simplifying board layout compared to standard 4-wire JTAG.
Is the MSP430F5419AIPZR pin-compatible with other devices in the MSP430F54xx family?
Yes, the MSP430F5419AIPZR in the 100-pin LQFP (PZ) package shares identical pinout and electrical characteristics with MSP430F5438AIPZ and MSP430F5436AIPZ - enabling drop-in replacement where flash size requirements align.
