MSP432P401MIRGCR - 48MHz ARM Cortex-M4F MCU 128KB Flash | Texas Instruments
料号： MSP432P401MIRGCR ✓ 量产中MSP432P401MIRGCR 概述
A SimpleLink MSP432P401x microcontroller is an ultra-low-power ARM Cortex-M4F MCU designed for battery-powered and energy-harvesting applications. The platform combines Cortex-M4 DSP performance with MSP430-class power efficiency, featuring seven low-power modes (LPM0-LPM4.5) that draw sub-µA standby current. The MSP432 family occupies the tier between 16-bit MSP430 devices and higher-power Cortex-M4 parts, and is positioned within the SimpleLink ecosystem of compatible wireless host MCUs that share drivers, RTOS support (TI-RTOS, FreeRTOS), and the CCS development environment.
Key features include 128 KB single-cycle Flash with 4-bank partitioning for in-field updates, 32 KB SRAM with parity, four 16-bit timers, two 32-bit timers, a 14-bit 1 MSPS SAR ADC with 16 channels and internal 1.2 V or 1.45 V reference, plus two comparators. The RGC package integrates a 9 mm × 9 mm VQFN with exposed thermal pad. Hardware cryptography acceleration and AES are absent on the M-class part (these are reserved for MSP432P401R higher-tier SKUs).
The MSP432P401M uses a Cortex-M4F core with MPU and FPU, supported by an integrated 8-channel DMA engine, SysTick timer, and a flexible clock tree with 48 MHz DCO, 32.768 kHz LFXT, and an internal REFO. On-chip peripherals include RTC, watchdog, and supply-voltage supervisor. The 14-bit ADC achieves 1 MSPS throughput with 16 single-ended or differential channels. The architecture nests balanced supplies with deep-sleep LPM3.5 current under 1 µA typical.
Typical applications include industrial sensor transmitters, smart metering endpoints, IoT edge nodes, building automation controllers, HVAC sensor interfaces, battery-powered medical monitors, and consumer wearables. The integrated precision ADC removes the need for an external converter in many sensor-conditioning designs.
Designers should budget for the 9 mm × 9 mm VQFN PCB footprint with a thermal pad for ground stitching and a 32.768 kHz crystal if RTC accuracy is required. The CCS IDE with XDS110 or XDS200 debug probe is recommended for development.

MSP432P401MIRGCR 适用于 7 应用s: Industrial IoT Sensor Node, Smart Metering Endpoints, Building Automation Controllers, Battery-Powered Wearable Health Monitor, Consumer IoT Edge Node, Portable Medical Diagnostic Device, Automotive Body Electronics (Non-Safety).
Industrial IoT Sensor Node
The MSP432P401MIRGCR's 80 µA/MHz active power and sub-µA LPM4.5 standby make it a fit for battery-powered industrial sensor nodes transmitting on LoRa, Wi-Fi, or sub-GHz radios. The integrated 14-bit 1 MSPS SAR ADC reads thermocouples, strain gauges, and 4-20 mA loops without an external ADC, while the 48 MHz Cortex-M4F with FPU runs edge analytics and AES-128 TLS handshakes before wake-up. Designers place the part between a 3.6 V Li-SOCl2 cell and a SimpleLink wireless co-processor; unlike a discrete MSP430 + external ADC architecture this SoC integrates everything on a 9 mm × 9 mm footprint, freeing board area for the radio and antenna. TI-RTOS or FreeRTOS handles task scheduling, and the 128 KB Flash supports OTA image swaps with the four-bank partitioner.
推荐
Smart Metering Endpoints
The MSP432P401MIRGCR is suited for water, gas, and heat metering endpoints that wake periodically, take measurements, and transmit over wireless M-Bus or LoRaWAN. The integrated 14-bit ADC handles pulse counting and analog flow-meter outputs, while LPM4.5 standby below 1 µA extends coin-cell battery life to 10+ years. Compared with a discrete MSP430 + ADC architecture, the MSP432P401M's Cortex-M4F with FPU accelerates metering math (FFT, RMS calculation) and TLS handshake for AMI networks. The 64-VQFN (RGC) package fits inside meter housings with strict height budgets; the wide 1.62-3.7 V supply accommodates 3.6 V Li-SOCl2 cells. The AES-ready MSP432P401R variant is firmware-compatible if hardware crypto is later required.
推荐
Building Automation Controllers
For HVAC controllers, lighting nodes, and BACnet/Modbus bridge devices, the MSP432P401MIRGCR delivers 48 MHz Cortex-M4F performance with the GPIO and UART count needed for multi-protocol industrial gateways. The integrated 14-bit ADC reads temperature, humidity, and CO2 sensors without an external converter, and the 32 KB SRAM holds Modbus TCP buffers with margin. Designers place the MCU at the heart of a 24V-bus powered controller; the part's 1.62-3.7 V supply is fed from a TPS5430 buck regulator with a wide Vin. Compared with a discrete MCU + ADC architecture, the integrated precision ADC achieves 1 MSPS throughput for fast control loops, while LPM3 standby at 1 µA keeps idle-zone power under 50 mW.
推荐
Battery-Powered Wearable Health Monitor
The MSP432P401MIRGCR's sub-µA standby and 80 µA/MHz active power fit wearable health monitors that wake on interrupt, sample heart-rate and motion sensors, and transmit over BLE. The integrated 14-bit ADC reads PPG and ECG analog front-ends without an external converter, while the Cortex-M4F FPU runs heart-rate-variability DSP and BLE stack encryption. Designers place the MCU at the center of a 3.0 V coin-cell powered band; the part's 1.62 V minimum supply handles end-of-life battery voltage. Compared with discrete MSP430 + BLE architectures, this SoC consolidates processing and analog on a 9 mm × 9 mm footprint, allowing smaller wearable enclosures. The integrated DMA engine reduces CPU wake time, extending battery life on each measurement cycle.
推荐
Consumer IoT Edge Node

The 48 MHz core runs Matter application logic, the 128 KB Flash holds the Matter stack and user app, and the 14-bit ADC reads analog sensors like ambient light and temperature. Designers place the MCU as the host controller next to a CC2652 wireless MCU running the radio; the 64-VQFN (RGC) footprint keeps the assembly under 50 mm². Compared with bare Cortex-M0+ parts, this SoC adds FPU and DSP for audio preprocessing, while LPM4.5 standby below 1 µA keeps always-listening voice-trigger power under 30 µA average.
推荐
Portable Medical Diagnostic Device
The MSP432P401MIRGCR's 14-bit 1 MSPS precision ADC and Cortex-M4F DSP performance fit portable diagnostic devices such as pulse oximeters, glucometers, and point-of-care analyzers. The integrated ADC reads electrochemical sensor outputs and converts them with 1 LSB precision, while the FPU accelerates filter and FFT routines for signal conditioning. The 80 µA/MHz active power and sub-µA standby let a 2x AA alkaline design run for 1000+ measurements, and the 1.62 V minimum supply handles end-of-life battery voltage. Designers place the MCU on a small PCB alongside a BLE modem; the 64-VQFN (RGC) 9 mm × 9 mm footprint fits inside a handheld enclosure with strict size budgets.
推荐
Automotive Body Electronics (Non-Safety)
For non-safety body electronics such as HVAC control panels, seat controllers, and ambient lighting, the MSP432P401MIRGCR provides 48 MHz Cortex-M4F performance with industrial-grade temperature range (-40 °C to +85 °C). The integrated 14-bit ADC reads potentiometers and thermistors, the UART/SPI/I2C interfaces drive display drivers and motor pre-drivers, and the 32 KB SRAM handles LIN protocol stacks with margin. Designers place the part at the heart of a 12V-bus powered module behind a load-dump-protected supply; the part's 1.62-3.7 V supply is fed from a wide-Vin buck like the LM53635. The 64-VQFN (RGC) package is footprint-compatible with the AEC-Q100 qualified MSP432P401RIPZ for safety-related variants in mixed-safety systems.

关键差异点
- Integrated 14-bit 1 MSPS precision ADC eliminates external converter （对比 MSP430F6736AIPZ (16-bit MCU + external sigma-delta ADC))
- Cortex-M4F with FPU enables DSP and floating-point math （对比 MSP430F147IPM (16-bit MSP430 core, no FPU))

设计说明
Estimated: at 48 MHz active mode with all peripherals enabled and 3.3 V supply, the MSP432P401M draws approximately 3.84 mA (80 µA/MHz × 48 MHz). For battery-powered designs targeting 10-year coin-cell life, use LPM4.5 deep-sleep mode with GPIO wake, which holds current below 1 µA. Place a 100 nF decoupling capacitor within 5 mm of the DVCC pins and a 4.7 µF bulk capacitor on the VCORE pin to support DC-DC switching transients.
The 64-VQFN (RGC) package requires a 9 mm × 9 mm PCB land pattern with a 5 mm × 5 mm thermal pad (EP) underneath. Connect the EP to a clean ground plane with at least 16 thermal vias (0.3 mm drill, 0.6 mm pitch) for heat dissipation. Place the 32.768 kHz crystal within 5 mm of the XIN/XOUT pins and route it over a continuous ground pour to minimize noise coupling into the RTC.
Do not skip the VCORE pin bulk capacitor - the internal DC-DC requires 4.7 µF minimum to maintain core-rail stability during active-to-sleep transitions. Avoid sharing ADC analog pins with high-frequency switching signals; the 14-bit ADC achieves 1 MSPS only with proper ground isolation. Ensure the JTAG/SWD TCK pin is pulled low or floating per the datasheet to prevent accidental debug entry during reset.
