STM32L4R5VGT6 - 120MHz Cortex-M4 MCU 1MB | STMicroelectronics
MPN: STM32L4R5VGT6 ✓ فعالSTM32L4R5VGT6 جائزہ
An ultra-low-power microcontroller is designed to balance processing performance, energy efficiency, and real-time control. The STM32L4 family belongs to the Arm Cortex-M4 microcontroller category and combines a processor core, embedded memory, communications peripherals, analog interfaces, and security-oriented peripherals within one device. Its Cortex-M4 architecture supports efficient digital signal processing and floating-point calculations while maintaining a broad embedded-control feature set.
Key characteristics include a 120 MHz maximum clock, 1 MB of flash, 640 KB of SRAM, and Arm Cortex-M4 instruction-set compatibility. USB OTG provides a standard peripheral interface for USB-connected control, data acquisition, or configuration applications. DFSD support expands the device's usefulness for external storage workflows, while the large SRAM capacity allows more data buffering and protocol processing to remain inside the microcontroller.
The STM32L4R5VGT6 combines a high-performance 32-bit core with low-power-oriented design. Its 1 MB flash supports larger embedded applications, and its 100-pin LQFP package provides a high pin count for external peripheral connections. Operating-voltage information identifies 1.8 V, 2.5 V, and 3.3 V supply options, allowing the device to fit industrial, communications, consumer, and embedded-control platforms whose interfaces and external components match those voltage levels.
Typical applications include USB-connected industrial control, low-power data loggers, sensor acquisition systems, digital audio processing, building automation equipment, and compact embedded gateways. The Cortex-M4 floating-point unit is particularly useful for control loops and signal-processing workloads that benefit from single-precision arithmetic without requiring a separate DSP.
PCB design should account for the 100 exposed leads, high-pin-count routing requirements, and the device's USB and storage interfaces. Confirm pin assignments, decoupling requirements, clock configuration, and peripheral multiplexing in the manufacturer datasheet and reference manual before releasing the PCB layout.
This page combines the STM32L4R5VGT6's core specifications, sourcing structure, family alternatives, and application guidance to support faster component selection and hardware planning for embedded-product teams.

عام استعمالات
STM32L4R5VGT6 کے لیے موزوں ہے 6 ایپلیکیشنs: USB Industrial Control, Low-Power Sensor Acquisition, Digital Audio Processing, External-Storage Data Logger, Building Automation Controller, Battery-Powered Embedded Gateway.
USB Industrial Control
The STM32L4R5VGT6 fits USB-connected industrial controllers because its Cortex-M4 core operates up to 120 MHz, 640 KB of SRAM can hold control state and buffers, and USB OTG provides a native communications path. A typical design would use the USB interface for configuration, status reporting, and control commands while dedicated timer and serial peripherals handle real-time tasks. The 100-pin LQFP package offers enough connections for sensors, actuator drivers, and status indicators. Validate USB suspend behavior, bus-routing impedance, ESD protection, and the device's power-management configuration in the manufacturer reference manual.

Low-Power Sensor Acquisition
The STM32L4R5VGT6 is suitable for compact sensor-acquisition equipment where processing capability, memory, and low-power operation must coexist. Its 120 MHz Arm Cortex-M4 core can execute filtering and calibration, while 640 KB of SRAM reduces pressure on external memory during sample buffering. The MCU can coordinate sensor inputs over its available serial or timer peripherals and place the system into a low-power state between acquisition events. The 100-pin LQFP package simplifies routing in industrial and laboratory equipment with numerous external connections. Confirm converter startup time, analog front-end settling, and wake-up timing during system-level power-budget validation.

Digital Audio Processing
The STM32L4R5VGT6 can serve as the control and signal-processing core in digital audio equipment because its Cortex-M4 architecture includes floating-point arithmetic and runs up to 120 MHz. The floating-point unit accelerates common filtering, mixing, and control calculations, while 1 MB of flash and 640 KB of SRAM provide room for code, lookup tables, and audio buffers. The device can coordinate audio interfaces, control amplifiers, and configuration storage while its low-power design supports portable equipment. Designers should evaluate real-time interrupt latency, DMA behavior, memory bandwidth, and clock-tree configuration to ensure deterministic audio performance.

External-Storage Data Logger
The STM32L4R5VGT6 fits a standalone data logger because DFSD support can connect the controller to compatible external storage while the 120 MHz Cortex-M4 core formats and compresses captured records. With 640 KB of SRAM, the MCU can maintain working queues and temporary processing buffers before data is written to storage. USB OTG adds a convenient path for configuration retrieval or log export, depending on the selected device role. The 100-pin LQFP package provides a practical number of external connections for storage, status indicators, and communication circuits. Check file-system compatibility, bus timing, brownout behavior, and data-integrity requirements during storage-device qualification.

Building Automation Controller
The STM32L4R5VGT6 is appropriate for a building-automation controller that must combine multiple external interfaces, event handling, and low-power operation. Its 100-pin LQFP package provides a broad connection count for sensors, relay drivers, communications transceivers, and local user interfaces. The Cortex-M4 core can supervise scheduled tasks, process sensor data, and manage protocol traffic, while the integrated USB OTG interface supports configuration and service access. DFSD support can support local configuration or logged event data where suitable storage hardware is used. Choose the package temperature grade according to the enclosure environment and verify communications timing, watchdog behavior, and brownout recovery during commissioning.

Battery-Powered Embedded Gateway
The STM32L4R5VGT6 supports battery-powered embedded gateways that need more processing capability than a small low-end controller while retaining access to low-power operating modes. The 120 MHz Cortex-M4 core handles protocol processing, local filtering, and data aggregation, and 640 KB of SRAM supports working buffers for short network transactions. USB OTG can be used for commissioning or maintenance connectivity, while DFSD support can provide local storage in suitable designs. The 100-pin LQFP package increases routing complexity but offers ample peripheral connectivity. Optimize the system around sleep-mode entry, wake-up latency, regulator efficiency, and the duty cycle of radio transmissions to meet the battery-life target.

ڈیزائن نوٹس
Route all 100 LQFP leads with the package's standard pad geometry and inspect the assembly drawing before fabrication. Place decoupling capacitors adjacent to the appropriate supply pins, keep sensitive analog and clock routes away from high-current switching nodes, and provide continuous ground-plane coverage beneath the device. USB traces require controlled impedance and short return paths.
Design the supply network for the STM32L4R5VGT6's 1.8 V, 2.5 V, or 3.3 V operating option and account for regulator tolerance, startup current, and peripheral load transients. Separate analog, digital, and potentially noisy supply domains according to the datasheet pin descriptions. Verify brownout behavior and ensure the MCU remains in a safe state during slow power ramps.
Do not treat every STM32L4-family ordering code as an interchangeable replacement. Match the exact R5VG configuration, flash size, SRAM size, package, temperature grade, and pin functions. After fitting STM32L4R5VGT7 or STM32L4R5VGT8, confirm clock limits, flash wait states, brownout settings, and peripheral mappings even though the PCB footprint remains unchanged.
Use the STMicroelectronics reference manual to assign alternate-function pins before finalizing the schematic. Leave required test points for reset, boot, debug, and clock signals, and maintain a clean analog supply path for sensor or signal-conditioning inputs. Check USB trace geometry and DFSD signal integrity against the configured clock and bus speed.
