MPN: STM32L4R9VGT6 ✓ सक्रियSTM32L4R9VGT6 अवलोकन
An ultra-low-power microcontroller is a semiconductor that controls an embedded system while minimizing energy consumption during active operation, sleep, shutdown, and battery-backed states. The STM32L4+ family sits within the broader hierarchy of microcontroller, embedded processor, and semiconductor categories. Its FlexPowerControl architecture is intended to extend operating time in battery-powered equipment without requiring a high-performance processor to remain active during idle periods.
Verified device features include an Arm Cortex-M4 32-bit RISC core, a 120 MHz maximum clock, and 1 MB of flash memory organized as 1M x 8. The STM32L4R9VG family supports a 1.71 V to 3.6 V operating supply range and temperature options extending from -40 °C to 85 °C or -40 °C to 125 °C. The STM32L4R9VG family also includes USB OTG and DFSD functionality according to the manufacturer listing.
Low-power operation is supported by a shutdown mode consuming 33 nA and a VBAT mode consuming 305 nA, as stated in the available datasheet summary. These figures are especially relevant for sensors, portable instruments, and battery-operated equipment that spend most of their service life in a low-current state. The 1 MB flash capacity allows larger firmware, data logs, and embedded user-interface assets to remain resident without an external program-memory device.
Typical uses include industrial sensing and control, connected sensor nodes, USB-enabled embedded equipment, data acquisition systems, and low-power consumer or medical products. The 100-pin LQFP package provides a higher pin count than compact MCU packages, making it suitable for designs requiring multiple peripheral connections while remaining compatible with established surface-mount manufacturing processes.
Designers should preserve the complete STM32L4R9VG pin assignment and review the manufacturer reference manual before routing USB, high-speed interfaces, power supplies, debug signals, and analog inputs. Correct decoupling, grounded return paths, clock planning, and low-power state transitions are essential for dependable operation. The available verified data does not provide a complete pin-by-pin assignment, so no pin names are inferred here.
This product record consolidates manufacturer positioning, distributor availability, verified electrical highlights, and same-family drop-in candidates with engineering trade-offs. It also identifies where complete RAM, GPIO, peripheral, timing, and package-thermal values require confirmation from the manufacturer documentation before a production design is released.

सामान्य अनुप्रयोग
STM32L4R9VGT6 के लिए उपयुक्त है 6 अनुप्रयोगs: USB-Enabled Embedded Control, Industrial Sensor Node, Battery-Powered Data Logger, Industrial Ethernet Gateway, Low-Power Instrument Controller, Medical and Environmental Monitoring.
USB-Enabled Embedded Control
The STM32L4R9VGT6 is suitable for USB-enabled embedded controllers because the verified Mouser specification identifies USB OTG, while its 120 MHz Cortex-M4 core and 1 MB flash provide room for USB device or host firmware, configuration data, and application logic. A USB interface is valuable for configuration, logs, firmware updates, and data exchange without adding a separate interface controller. The implementation must follow the manufacturer USB electrical and layout guidance, including correct supply, ground, signal-integrity, and firmware requirements. Because the supplied data does not enumerate USB speed or endpoint details, those specifications must be confirmed in the complete datasheet and reference manual before connector or host compatibility is committed.
अनुशंसित
Industrial Sensor Node
The STM32L4R9VGT6 fits industrial sensor nodes that must sample, filter, and store information while keeping standby consumption low. Its 120 MHz Cortex-M4 core supports responsive control and signal-processing tasks, and 1 MB of flash allows local firmware, calibration data, and diagnostic logic to be stored on-chip. The verified low-power figures of 33 nA in shutdown mode and 305 nA in VBAT mode are especially useful when the node spends long intervals between measurements. Designers should still confirm analog channels, ADC characteristics, timers, and I/O availability in the manufacturer documentation. Temperature version selection is critical when the enclosure is exposed to conditions beyond the target’s 85 °C standard-temperature rating.
अनुशंसित
Battery-Powered Data Logger
The STM32L4R9VGT6 is well matched to battery-powered data loggers because its STM32L4+ architecture combines a 120 MHz processing core with shutdown and VBAT modes. The verified 33 nA shutdown current and 305 nA VBAT current can reduce standby demand in systems that wake periodically to capture measurements. Its 1 MB flash also provides local storage for buffered records, timestamps, and event metadata, reducing the amount of data transmitted over a radio link. Actual battery life depends on active current, wake interval, sensor load, and regulator efficiency, none of which were supplied as verified values. Designers should also verify brownout behavior, RTC retention, and write endurance before defining the logging interval.
अनुशंसित
Industrial Ethernet Gateway
The STM32L4R9VGT6 can serve as the application processor in an industrial Ethernet gateway when its confirmed interface set, memory, and timing meet the design requirements. The 120 MHz Cortex-M4 core can execute protocol processing, local control, diagnostics, and configuration tasks, while 1 MB of flash provides room for embedded firmware. A companion Ethernet PHY such as the LAN8742A-CZ can handle the physical-layer network connection, subject to pin-level and timing verification. The MCU is also suitable for low-power operation between network events, with the verified 33 nA shutdown and 305 nA VBAT figures supporting aggressive duty cycling. Ethernet timing, PHY interface signals, isolation, and electromagnetic-compatibility requirements must be reviewed before production release.
अनुशंसित
Low-Power Instrument Controller
The STM32L4R9VGT6 is appropriate for portable measurement instruments that combine responsive control with long battery life. Its 120 MHz Cortex-M4 core can handle acquisition sequencing, display updates, local data processing, and user-interface logic, while 1 MB flash reduces the need for external program storage. The 1.71 V to 3.6 V operating range supports integration with low-voltage power trees, and the verified low-power modes are useful during calibration gaps or inactive measurement periods. Analog accuracy and sensor excitation are not specified in the retrieved data, so they must be validated separately from the MCU selection. Engineers should also assess regulator efficiency, startup time, and the effect of peripherals left enabled between measurements.
अनुशंसित
Medical and Environmental Monitoring
The STM32L4R9VGT6 can support compact medical or environmental monitoring products that require local control, flexible connectivity, and low standby demand. The 1 MB flash capacity accommodates application firmware, self-tests, configuration, and recorded event information, while the 120 MHz Cortex-M4 core provides headroom for filtering and control. The verified shutdown and VBAT currents are advantageous in instruments that operate intermittently, although regulatory and clinical requirements may impose additional selection criteria not present in the supplied data. The standard-temperature suffix must be checked against the intended ambient range. Confirm electrical isolation, sensor accuracy, reset behavior, and applicable medical-device quality requirements before using this MCU in a regulated product.

डिज़ाइन नोट्स
Design the supply rail for the verified 1.71 V to 3.6 V STM32L4R9VG operating range, including startup, USB attachment, and low-power transitions. Place the required input and bulk decoupling capacitors directly beside the relevant supply and ground pins, and route return current through the shortest possible path. Do not infer capacitor values from the family summary because the complete pinout, decoupling recommendations, and USB current requirements were not included in the verified data.
Use a 14 x 14 mm 100-pin LQFP land pattern and verify pin 1 orientation against the manufacturer package drawing before release. Preserve short differential routing for USB and any high-speed interfaces, provide a continuous ground reference, and place supporting components away from exposed clock and signal paths. Because the complete STM32L4R9VGT6 pin table was unavailable in the supplied data, the PCB netlist must be checked against the current STMicroelectronics datasheet rather than this page alone.
Do not treat the same package outline as proof of an electrically identical substitution. STM32L4R5, STM32L4R7, and STM32L4R9 devices can differ in flash capacity, peripherals, clock-related limits, and software support. For each candidate, compare the complete pin table, power characteristics, startup behavior, firmware device identifier, peripheral availability, and package markings. A PCB may fit the replacement, but firmware and qualification checks remain necessary.
Although the verified sources identify a -40 °C to 85 °C standard-temperature option and a -40 °C to 125 °C option, they do not provide the package thermal-resistance values needed for a junction-temperature calculation. Use the manufacturer package data for theta_JA or theta_JC and the actual PCB copper area in production analysis. Validate the worst-case ambient, operating mode, clock rate, and regulator dissipation rather than relying on the nominal 120 MHz frequency alone.
अनुपालन जानकारी
The verified search results identify the STM32L4R9VG product family and its temperature options but do not provide explicit RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declarations. These fields therefore remain unknown rather than being inferred.
