Product details
Overview
MSP430F5419IPZR from Texas Instruments is a 16-bit ultra-low-power mixed-signal microcontroller featuring 128 KB Flash, 16 KB RAM, a 12-bit ADC with 14 external + 2 internal channels, three 16-bit timers (Timer_A with 5+3 CC registers, Timer_B with 7 CC registers), four USCI modules (2 UART/IrDA/SPI + 2 I²C/SPI), and RTC functionality. It operates from 2.2 V to 3.6 V and targets battery-powered sensor systems and digital timers.
For engineers reviewing the MSP430F5419IPZR datasheet, MSP430F5419IPZR pinout, MSP430F5419IPZR application, or MSP430F5419IPZR equivalent, key selection criteria include its LQFP-100 package, 87 GPIOs, integrated LDO core regulation, wake-up time <5 µs from LPM3, and support for crystal oscillators up to 32 MHz - all critical for low-power embedded timing and measurement designs.
Technical Context
The MSP430F5419IPZR implements a CPUXV2 16-bit RISC core with constant generators and extended memory addressing, paired with a Unified Clock System (UCS) that includes FLL stabilization, REFO and VLO internal sources, and dual crystal support (XT1 for 32 kHz, XT2 up to 32 MHz). Its power architecture integrates an on-chip LDO, supply voltage supervisor (SVS), and brownout reset (BOR) for robust operation across voltage transients.
Peripherals are tightly synchronized via the UCS: ADC12_A uses programmable ADC12CLK derived from MCLK/SMCLK/ACLK; DMA transfers are triggered by timer, ADC, or USCI events; and RTC_A operates independently using ACLK from XT1 or VLO. All three timers support capture/compare, PWM, and interval timing with shadow register support in TB0.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | CPUXV2 16-bit RISC with 16-bit registers and constant generators - enables compact, efficient code for sensor firmware and real-time control loops. |
| Flash / RAM | 128 KB Flash / 16 KB RAM - sufficient for complex sensor fusion algorithms and bootloader + application partitioning. |
| ADC Resolution & Channels | 12-bit ADC with 14 external + 2 internal analog inputs - supports multi-sensor acquisition (e.g., temperature, voltage, current) without external mux. |
| Timers | TA0 (5 CC), TA1 (3 CC), TB0 (7 CC with shadow registers) - enables simultaneous PWM generation, input capture, and precise event timing across multiple peripherals. |
| USCI Interfaces | 4 USCI modules: USCI_A0–A3 (UART/IrDA/SPI), USCI_B0–B3 (I²C/SPI) - allows concurrent communication with UART-based host, I²C sensors, and SPI displays or flash memory. |
| Power Modes | LPM3 (2.6 µA @ 3.0 V, RTC active) and LPM4 (1.69 µA @ 3.0 V) - enables multi-year battery life in metering and thermostat applications. |
| Wake-up Time | <5 µs from LPM3 to active mode - ensures rapid response to external interrupts (e.g., button press, alarm trigger) without missing edge events. |
Pinout & Package
LQFP-100 package (14 mm × 14 mm), 87 usable I/O pins, with dedicated analog supply (AVCC/AVSS), digital supplies (DVCC/DVSS ×4), regulated core output (VCORE), and JTAG/SBW debug interface (PJ.0–PJ.3, TEST/SBWTCK, RST/NMI).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P1.0/TA0CLK/ACLK | Timer & clock I/O | Configurable as TA0 clock input or ACLK output - enables flexible clock tree routing for timer synchronization or system clock distribution. |
| P2.4/RTCCLK | Real-time clock output | Provides ACLK-divided RTC clock signal externally - useful for driving auxiliary logic or synchronizing external timers. |
| P2.7/ADC12CLK/DMAE0 | ADC clock & DMA trigger | Outputs ADC conversion clock and serves as DMA external trigger - allows deterministic timing of ADC-triggered data transfers without CPU intervention. |
| P4.7/TB0CLK/SMCLK | Timer & system clock I/O | Accepts external clock for TB0 or outputs SMCLK - supports high-precision frequency measurement or clock forwarding to external ICs. |
| P7.0/XIN & P7.1/XOUT | Low-frequency crystal interface | Connects 32.768 kHz crystal for RTC accuracy - requires no external load capacitors when used with internal oscillator circuitry. |
| P5.2/XT2IN & P5.3/XT2OUT | High-frequency crystal interface | Supports crystals up to 32 MHz for MCLK/SMCLK - enables full-speed USB-capable peripheral operation (via USCI) and fast ADC sampling. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated LDO core regulator | Programmable VCORE voltage reduces sensitivity to supply ripple and eliminates need for external core LDO in space-constrained designs. |
| Hardware multiplier (MPY32) | Supports 32-bit signed/unsigned multiply in single cycle - accelerates filtering, FFT, and PID calculations in sensor firmware. |
| 3-channel DMA controller | Enables zero-CPU-overhead data movement between ADC, USCI, and RAM - essential for continuous sensor logging or streaming UART-to-SPI bridging. |
| Autoscan ADC mode | Automatically sequences conversions across up to 16 channels - simplifies firmware for multi-input analog monitoring without manual channel switching. |
| RTC with alarm & calibration | Retains time/date across LPM4 and supports programmable alarms - enables scheduled wake-up for periodic measurements or calendar-based device control. |
Applications
| Remote Control Unit | Digital Thermostat |
|---|---|

IC Role / Device Role / Timing Role: Signal conditioner and preprocessor - digitizing, filtering, and buffering analog data prior to wireless upload. Use Value: Autoscan ADC + DMA offloads CPU during acquisition; LPM3 with RTC allows precise duty-cycled sampling every 10 seconds. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F5438IPZR | 256 KB Flash, 87 I/O, same LQFP-100 package, identical peripheral set - differs only in Flash size and part number suffix. | Preferred where firmware complexity demands >128 KB Flash (e.g., OTA updates, dual-bank bootloaders). | Select MSP430F5438IPZR if future firmware growth or field-upgrade capability is required; otherwise MSP430F5419IPZR offers optimal cost/performance balance. |
| MSP430F5418IPNR | Same 128 KB Flash and peripherals, but in 80-pin LQFP (PN) package with 67 I/O - lacks P8.x, P9.x, P10.x, P11.x pins and one USCI_A/USCI_B pair. | Suitable for space-constrained PCBs where fewer GPIOs and reduced communication interfaces are acceptable. | Choose MSP430F5418IPNR only when board area is critical and full 87-I/O count or four USCI modules are unnecessary. |
Compared with MSP430F5438IPZR and MSP430F5418IPNR, the MSP430F5419IPZR delivers the optimal trade-off: full peripheral complement and 87 I/O in LQFP-100 at lower cost than the 256 KB variant, while avoiding the I/O and interface limitations of the 80-pin version.
