부품 번호: STM32L4R9ZGT6 ✓ 활성STM32L4R9ZGT6 개요
An ultra-low-power microcontroller is an embedded semiconductor designed to maintain useful processing, sensing, and communication functions while minimizing energy consumption. The STM32L4+ hierarchy progresses from the STM32L4R9 device family to an Arm Cortex-M4 microcontroller, an embedded processor, and ultimately a semiconductor used in battery-powered and energy-conscious electronic systems. FlexPowerControl supports operating modes suited to applications where standby and shutdown current can determine practical battery life.
The STM32L4R9ZGT6 operates from a 1.71 V to 3.6 V supply range and is available in temperature grades extending to 85 °C or 125 °C, depending on the exact orderable configuration. Its 120 MHz Arm Cortex-M4 core provides substantially more performance headroom than lower-frequency microcontrollers while retaining the compact package, 1 MB Flash, and low-power architecture of the STM32L4+ family. The integrated floating-point unit supports efficient control and signal-processing workloads.
The device includes 112 I/O in its 144-lead package, along with USB OTG and DFSD functionality. These interfaces enable removable storage, data acquisition, firmware update, and external storage applications without requiring discrete interface controllers. According to the STMicroelectronics STM32L4R9ZG product page, the STM32L4R5xx, STM32L4R7xx, and STM32L4R9xx devices share the ultra-low-power STM32L4+ platform and Arm Cortex-M4 architecture.
Low-power features include a 305 nA VBAT mode for the real-time clock and 32 × 32-bit backup registers, plus a 33 nA shutdown mode. These figures make the MCU applicable to environmental sensors, compact industrial recorders, portable measurement equipment, and other systems that spend substantial time between active processing intervals.
When designing around the STM32L4R9ZGT6, preserve the 1.71 V to 3.6 V supply limits, use suitable decoupling close to the supply pins, and verify every peripheral operating condition against the manufacturer datasheet. Temperature grade, firmware configuration, power sequencing, and low-mode entry conditions should be validated together rather than treated as independent parameters.
This product page consolidates verified manufacturer and distributor information, package details, low-power figures, replacement guidance, and application-oriented engineering context. It also distinguishes true same-package drop-in candidates from broader functional alternatives, helping designers compare procurement options without overlooking the differences that affect qualification.

일반적인 애플리케이션
STM32L4R9ZGT6 적합 용도: 6 애플리케이션s: Battery-Powered Environmental Sensors, Portable Data Acquisition, Industrial Sensor Nodes, USB-Conditioned Control Panels, Medical Monitoring Equipment, Remote Monitoring and Communications.
Battery-Powered Environmental Sensors
The STM32L4R9ZGT6 fits environmental sensing products because its STM32L4+ architecture combines a 120 MHz Arm Cortex-M4 core with a 305 nA VBAT mode and a 33 nA shutdown mode. The MCU can periodically acquire sensor data, process it locally, and then return to a low-current state between measurements. Its 1 MB Flash provides room for firmware, calibration data, and local logs, while the 1.71 V to 3.6 V supply range accommodates energy-harvesting and low-energy 3 V power systems. Designers should calculate the complete duty-cycle current because sensor, regulator, and communication loads can dominate total consumption.
Portable Data Acquisition
The STM32L4R9ZGT6 is well suited to portable measurement equipment that must combine flexible digital control with low standby consumption. Its 120 MHz Cortex-M4 core provides timing headroom for digital filtering and control, and the hardware floating-point unit assists with arithmetic-heavy signal processing. The 1 MB Flash can hold application firmware and embedded configuration, while USB OTG simplifies configuration transfer or data export. For a compact recorder, engineers can use shutdown mode between acquisition bursts and VBAT mode to maintain the RTC and 32 x 32-bit backup registers with low current.
Industrial Sensor Nodes
The STM32L4R9ZGT6 supports industrial sensor-node designs requiring a 120 MHz control processor, USB connectivity, and a temperature-qualified 144-LQFP package. The 112 I/O provide substantial interface capacity for sensors, discrete inputs, actuators, and status indicators, reducing the need for external I/O expanders. Low-power modes are valuable in fixed installations where sensors must operate for long periods between maintenance visits. The 125 °C-capable target grade should be selected only where the enclosure, regulator, and other components also tolerate the environment; otherwise an industrial-grade alternative may be preferable.
USB-Conditioned Control Panels
The STM32L4R9ZGT6 is appropriate for USB-connected control and configuration panels where local processing, storage access, and low-power behavior are needed. Its USB OTG interface supports direct USB communication, while DFSD provides a dedicated route to compatible file-system media. The 120 MHz Arm Cortex-M4 core can manage a user interface, communications, and control logic without requiring a separate processor. A practical implementation should reserve internal Flash for firmware and updates, route external storage through DFSD, and account for USB suspend behavior and regulator quiescent current when calculating standby performance.
Medical Monitoring Equipment
The STM32L4R9ZGT6 can serve as the central controller in compact medical monitoring equipment when the design requires real-time control, USB connectivity, and reduced energy use. The 120 MHz Cortex-M4 core and hardware FPU support efficient sampling control and filtering, while 1 MB Flash accommodates firmware and configuration. Low-power modes are useful in portable instruments that operate intermittently, and the 144-LQFP package exposes 112 I/O for sensors, displays, and communication links. Medical use requires complete application-specific risk review, electrical-safety analysis, validation of relevant external standards, and confirmation that every selected system component meets its intended requirements.
Remote Monitoring and Communications
The STM32L4R9ZGT6 is suitable for remote monitoring equipment that must periodically collect information, manage local control functions, and communicate efficiently. Its 120 MHz processing rate provides responsive protocol handling and application logic, while USB OTG supports local configuration or tethering during installation and maintenance. The 33 nA shutdown figure is useful for duty-cycled remote endpoints, and VBAT operation can retain RTC and backup-register state at 305 nA. A complete deployment must budget power for the communications module, sensors, regulator losses, and network retries, since the MCU's standby figures alone do not determine field battery life.

설계 노트
The STM32L4R9ZGT6 supports a 1.71 V to 3.6 V operating range, so the regulator must remain inside that window under transient, load, and temperature conditions. Low-current claims should be measured at the system level because the MCU's 33 nA shutdown and 305 nA VBAT figures exclude sensors, radios, regulators, and leakage. Use the manufacturer's mode-entry sequence and verify whether a backup domain remains powered before changing the operating-state policy.
Place input, output, and bypass capacitors close to the corresponding supply pins, following the reference layout and capacitor values in the STM32L4R9xx datasheet. The 144-LQFP footprint has fine-pitch leads, so routing must preserve clearance for assembly and inspection. USB and DFSD traces also require controlled geometry and return paths; keep switching or high-current signals away from sensitive analog and communication nets wherever the board area permits.
Although the MCU can operate in grades extending to 125 °C, the complete assembly must remain below its own thermal limits. Use the LQFP exposed thermal performance only as specified, provide adequate copper and via distribution, and include temperature sensors where thermal runaway matters. Estimated junction temperature must be calculated from measured or worst-case processor dissipation and the board-specific thermal resistance rather than from ambient temperature alone.
Do not treat a same-package STM32L4R9 variant as an automatic substitution. Confirm the exact orderable code, pin definitions, flash size, temperature ceiling, supply limits, peripheral set, and lifecycle status. Firmware may require device-ID handling, and changing temperature or package codes can affect qualification. For cross-vendor alternatives, rebuild the firmware and rerun timing, low-power, USB, DFSD, and environmental validation because pin placement alone does not establish software compatibility.
