MPN: STM32L4R5QGI6 ✓ সক্রিয়STM32L4R5QGI6 সারাংশ
An ultra-low-power microcontroller is an embedded semiconductor designed to execute firmware while minimizing energy consumption during active operation, standby, shutdown, and battery-backed operation. The STM32L4R5 belongs to the STM32L4 family hierarchy of Arm Cortex-M4 MCUs, combining real-time processing efficiency, embedded Flash, SRAM, analog and digital peripherals, and multiple low-power modes for compact sensing and control systems.
Key characteristics include a 120 MHz Arm Cortex-M4 core with floating-point unit, 1 MB of embedded Flash, a 1.71 V to 3.6 V operating supply range, and USB OTG connectivity. FlexPowerControl supports low-power operation, while the verified family data specifies 33 nA shutdown current and 305 nA VBAT mode consumption for RTC and 32 backup registers. DFSD support expands the design options available for secure digital storage and firmware data workloads.
The STM32L4R5 architecture is tailored for high-throughput, low-power embedded control. Its 32-bit Cortex-M4 processor includes hardware floating-point support for efficient control-loop, signal-processing, and math-heavy calculations. A large pin count provides extensive peripheral connectivity, while the 7 x 7 mm UFBGA package supports compact PCB layouts when adequate assembly capability and careful escape-routing are available.
Typical applications include industrial sensor nodes, compact data loggers, USB-connected embedded controllers, low-power industrial equipment, DFSD-based portable systems, and battery-operated sensing platforms. The combination of 1 MB Flash and USB OTG also makes the MCU suitable for firmware-intensive peripheral control where local code storage and direct USB connectivity are valuable.
Designers should confirm the complete pin assignment, exposed-pad requirements, supported peripherals, decoupling network, and operating-temperature grade against the manufacturer datasheet before layout release. High-density UFBGA construction also requires assembly-capable interconnect, solder-mask-defined geometry, and adequate thermal design for the selected power budget.

সাধারণ ব্যবহার
STM32L4R5QGI6 এর জন্য উপযুক্ত 6 অ্যাপ্লিকেশনs: USB-Connected Industrial Sensor Node, Low-Power Environmental Monitor, Portable DFSD Data Logger, Compact Real-Time Control Module, Battery-Powered Portable Instrument, Compact Networked Edge Controller.
USB-Connected Industrial Sensor Node
The STM32L4R5QGI6 fits a compact USB-connected sensor node because its 120 MHz Arm Cortex-M4 core provides control and signal-processing performance, while 1 MB of Flash supports local firmware and configuration data. USB OTG allows the controller to connect directly to a host for configuration, logging, or firmware updates without adding a separate USB interface IC. Place the MCU beside the sensor interface and route USB D+ and D- as a controlled differential pair. The 132-UFBGA package reduces board area, but its 132 balls require careful escape routing, via-in-pad or via adjacent to each signal, and assembly support. Verify the final USB routing and power requirements against the manufacturer implementation guidance.

Low-Power Environmental Monitor
The STM32L4R5QGI6 is well suited to environmental monitoring because the verified family data identifies FlexPowerControl, 33 nA shutdown current, and 305 nA VBAT mode current. Its 120 MHz Cortex-M4 performance allows the same controller to filter sensor readings, evaluate thresholds, and manage local events rather than acting only as a low-power data logger. Use shutdown or the appropriate low-power mode between measurement cycles when the application permits wake-up through an external event. The 1 MB Flash can hold calibration tables and staged firmware. Battery-life calculations must include sensor current, regulator leakage, wake timing, and communication duty cycle because the MCU's shutdown figure does not represent complete system consumption.

Portable DFSD Data Logger
The STM32L4R5QGI6 supports a portable DFSD data logger by combining its documented DFSD capability with 1 MB of internal Flash and a 120 MHz Cortex-M4 processor. The MCU can coordinate file-system access, buffer records, maintain timestamps, and supervise card insertion or removal while keeping the control logic compact. Its low-power operating options are valuable in field equipment that spends substantial time idle between logging sessions. The 132-UFBGA package leaves limited board area for external storage and supporting circuitry, so component placement should prioritize short DFSD signal routing, controlled impedance where required, and a stable supply for the storage device. Confirm the supported card characteristics and bus timing in the complete manufacturer documentation.

Compact Real-Time Control Module
The STM32L4R5QGI6 provides the processing headroom for a compact real-time control module because the 120 MHz Arm Cortex-M4 core includes floating-point capability for control algorithms and signal calculations. The 1 MB Flash supports a meaningful embedded application rather than a minimal firmware image, while the 132-UFBGA package allows the controller to sit close to power stages and sensors. Place the MCU centrally to balance high-speed control paths, keep switching nodes away from sensitive inputs, and provide local bulk and bypass capacitance around the 1.71 V to 3.6 V supply domain. Check peripheral availability, timer channels, analog functions, and pin multiplexing against the exact 132-UFBGA device before schematic capture.

Battery-Powered Portable Instrument
The STM32L4R5QGI6 is appropriate for a battery-powered portable instrument because it combines a 120 MHz Cortex-M4 core, 1 MB Flash, and verified low-power capabilities in a 7 x 7 mm 132-UFBGA package. It can manage display controls, user inputs, data acquisition, and USB charging or configuration functions without requiring a separate high-performance communications controller. The device's 33 nA shutdown current and 305 nA VBAT mode current provide useful baseline figures for retention and standby planning, but they are not complete system current. Use the exact state-transition timing from the manufacturer documentation and include regulator, display, pull-up, and sensor leakage in the final battery budget.

Compact Networked Edge Controller
The STM32L4R5QGI6 can serve as the host controller in a compact networked edge device, with its 120 MHz Cortex-M4 core handling protocol processing, local control, and data preparation. The documented USB OTG function provides a direct connection path for configuration or upstream service, while the available GPIO and bus resources can support sensors and status indicators. A network companion such as the LAN8742A-CZ can add Ethernet connectivity, but its interface requirements and the MCU's enabled peripheral set must be confirmed from the exact device documentation. In the layout, isolate Ethernet and USB routing from sensitive analog inputs, provide local decoupling at the MCU, and review low-power behavior across active and network-idle states.

ডিজাইন নোট
The 132-UFBGA package requires deliberate escape routing because its 7 x 7 mm body has densely spaced balls. Place the MCU according to the manufacturer land pattern, provide the required via configuration, and route high-speed or sensitive signals first. Keep USB and communication paths away from switching nodes and analog inputs. Because a complete pinout was not present in the supplied sources, the schematic and PCB should not be released until every ball, power domain, ground connection, and package-specific assembly requirement has been checked against the current manufacturer drawing.
Design the supply network for the documented 1.71 V to 3.6 V operating range and verify the exact regulator, bypass, and decoupling requirements for the selected package. Place bulk and high-frequency decoupling close to the device power balls, use short return paths through the ground grid, and avoid routing sensitive inputs beneath or immediately beside noisy supply paths. The verified 33 nA shutdown and 305 nA VBAT figures are useful for power-budget estimates, but they do not describe active current or total board leakage.
Do not treat a shared STM32L4-family name as proof that every software feature and pin assignment is interchangeable. The target is specifically identified as a 120 MHz Cortex-M4 device with 1 MB Flash, USB OTG, and DFSD support. Before substituting a same-brand candidate, check the exact pin table, memory capacity, peripheral availability, bootloader behavior, clock tree, low-power modes, and package drawing. Also verify that the board footprint, exposed-pad treatment, and assembly process remain unchanged.
Use the manufacturer thermal model and exposed-pad connection guidance when estimating junction temperature. The supplied snippets do not provide power dissipation, thermal resistance, or maximum junction-temperature figures, so a reliable thermal calculation cannot be completed from the available data. Preserve the recommended ground-pad geometry, use adequate copper without creating assembly voiding, and evaluate the worst-case ambient temperature, I/O activity, and supply configuration. Any junction-temperature estimate must be labeled as an engineering calculation rather than a datasheet guarantee.
কমপ্লায়েন্স তথ্য
The supplied distributor snippets do not explicitly provide RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declarations for the exact MPN. These statuses must be confirmed from current STMicroelectronics product and material documentation.
