STM32L4Q5AGI6 Présentation
A microcontroller is a programmable system-on-chip that integrates a CPU core, nonvolatile program memory, volatile data memory, peripherals, and interface controllers on one semiconductor device. The STM32L4 family belongs to the Arm Cortex-M microcontroller hierarchy and targets embedded control, communications, sensor processing, human-machine-interface, and low-power edge applications. Arm Cortex-M4 processors use the Thumb instruction set and support efficient interrupt-driven real-time control.
Verified headline features include an Arm Cortex-M4 core, 120 MHz maximum operating frequency, 150 DMIPS performance, 1 MB Flash, and 320 KB SRAM. The part also provides an FPU, LCD-TFT support, USB OTG, DFSD, hardware AES, and PKA. These resources combine high processing throughput with a broad peripheral set, reducing the need for external memory, cryptographic accelerators, storage controllers, and display-interface logic in compact embedded systems.
The STM32L4 architecture targets power-constrained products while retaining a broad set of communication and security interfaces. Flash capacity supports substantially larger firmware than smaller Cortex-M devices, while SRAM accommodates buffers, protocol stacks, graphics state, and real-time workloads. Hardware AES and PKA are particularly useful when a design must protect data or execute cryptographic operations with less software overhead. USB OTG expands connectivity options for peripherals, storage, charging, and host or device roles.
Typical applications include connected industrial sensors, USB data acquisition, secure access-control terminals, low-power data loggers, compact human-machine-interface controllers, and embedded gateways. The 169-UFBGA package minimizes board area but requires careful escape routing, inspection, and assembly planning. Because the complete exposed-pad pin map and detailed electrical limits are not contained in the supplied search records, engineers should confirm them against the official STMicroelectronics STM32L4Q5xx datasheet before layout or firmware deployment.
For robust implementation, preserve the datasheet-required decoupling near supply pins, route high-speed and sensitive signals with controlled return paths, and validate standby, wake-up, USB, and peripheral timing in the final board. Programming tooling, bootloader behavior, clock configuration, and low-power modes should also be verified from the official device documentation rather than inferred from distributor summaries.
This page combines verified manufacturer and distributor information, procurement links, application engineering guidance, and explicit data gaps for pin-level and pricing validation. It is intended to accelerate component discovery while preserving traceability to the official STM32L4Q5xx datasheet and current distributor records as of 2026-10-23.

Applications typiques
STM32L4Q5AGI6 convient pour 6 applications: USB Connected Data Acquisition, Industrial Sensor Gateway, Secure Access-Control Terminal, Low-Power Environmental Logger, Compact Human-Machine Interface, Portable Medical Monitoring Device.
USB Connected Data Acquisition
The STM32L4Q5AGI6 fits USB data-acquisition controllers because its verified 120 MHz Arm Cortex-M4 core, FPU, 320 KB SRAM, and USB OTG provide a capable combination for sampling control, buffering, and host or device communication. A practical design can use the MCU to coordinate sensors, process data, and transfer records to a computer or storage peripheral. The DFSD feature also supports external storage workflows. The principal tradeoff is routing and layout complexity: the 169-UFBGA requires dense escape routing, and USB signal integrity, power sequencing, and supported operating roles must follow the official datasheet.
Recommandé
Industrial Sensor Gateway
The STM32L4Q5AGI6 is suitable for compact industrial sensor gateways where an Arm Cortex-M4 device must combine real-time control, communications, local storage, and security. Its verified 120 MHz performance and 320 KB SRAM support protocol processing and buffering, while 1 MB Flash provides room for firmware, drivers, and update logic. DFSD can extend local storage, and AES and PKA accelerate cryptographic workloads. Deployments should confirm industrial temperature requirements, sustained communication duty cycle, watchdog behavior, and low-power wake-up performance against the manufacturer documentation before production release.
Recommandé
Secure Access-Control Terminal
The STM32L4Q5AGI6 aligns with secure access-control terminals that combine local credential processing, a compact display interface, and network or USB communications. Verified LCD-TFT support assists human-machine-interface designs, while AES and PKA provide hardware-assisted cryptographic processing. The 120 MHz Cortex-M4 core can coordinate display updates, input handling, communications, and event logging, and 1 MB Flash allows a comparatively substantial embedded application. Design validation must still cover credential-storage architecture, timing behavior, security implementation, package escape routing, and the exact peripheral pin assignments.
Recommandé
Low-Power Environmental Logger
The STM32L4Q5AGI6 can serve as the control core of a low-power environmental data logger because the STM32L4 family targets ultra-low-power embedded operation and the part includes 320 KB SRAM for working data. DFSD supports external storage-oriented designs, while USB OTG can simplify configuration and data transfer. Engineers should define a duty cycle that spends most of its time in an appropriate low-power mode and reserve processing time for sensor sampling, timestamp storage, and interface management. Battery life, wake-up latency, and peripheral shutdown behavior must be measured with the actual sensors and verified from the datasheet.
Recommandé
Compact Human-Machine Interface
The STM32L4Q5AGI6 is a logical controller for compact LCD-based human-machine interfaces because verified features include LCD-TFT support, a 120 MHz Cortex-M4 core, FPU, 320 KB SRAM, and 1 MB Flash. Those resources can support graphics updates, touch or key input, status feedback, communications, and application logic in a single controller. The 169-UFBGA 7 mm × 7 mm package enables compact layouts, but its 169-ball interface requires careful fanout and assembly planning. Developers should confirm panel voltage, timing, memory-bandwidth, pin-multiplexing, and low-power display requirements directly from the STM32L4Q5xx documentation.
Recommandé
Portable Medical Monitoring Device
The STM32L4Q5AGI6 can support portable medical-monitoring electronics when a design requires an efficient Cortex-M4 core, 1 MB Flash, 320 KB SRAM, USB connectivity, and hardware cryptography. These verified resources suit sensor acquisition, signal conditioning control, local filtering, secure data transfer, and event logging. AES and PKA may support security-sensitive data workflows, while the low-power family positioning helps manage battery consumption. Medical suitability is system-dependent: developers must validate electrical isolation requirements, accuracy, alarm timing, software risk controls, radiation limits, and regulatory evidence for the finished product.

Notes de conception
Do not begin PCB routing from distributor summaries. Download the official STM32L4Q5xx pin-definition tables and confirm every one of the 169-UFBGA connections, including power, ground, decoupling, exposed-pad, and alternate-function requirements. Start escape routing from the ball map and preserve the package’s thermal and assembly geometry. Because the verified records do not supply individual pin assignments, using a generated or assumed BGA map can cause power, boot, USB, or peripheral failures.
Implement the STM32L4Q5AGI6 supply network from the manufacturer’s recommended component and layout guidance. Place required bulk and local decoupling capacitors at the specified pins, maintain short return paths, and separate noisy digital return currents from sensitive analog routing. Validate startup, reset, brownout behavior, and simultaneous USB activity on the finished board. Do not infer voltage limits or capacitor values from distributor snippets.
USB OTG and DFSD interfaces demand controlled routing and complete reference planes. Follow the datasheet’s signal, impedance, length, and shielding guidance; avoid long stubs, splits across plane boundaries, and unnecessary loops. Confirm whether each interface is used in host or device mode and whether external components are mandatory. High-frequency edge rates can radiate even when the 120 MHz core clock is low relative to modern signal-processing speeds.
The 169-UFBGA package is optimized for compact boards, but power loss still creates junction heating. Calculate worst-case dissipation from the actual supply voltage, I/O loading, core activity, and selected clock configuration, then compare the resulting junction temperature with the manufacturer’s limits. Ensure the ball array has adequate ground and thermal connectivity and verify board copper effects in the actual assembly. This note is guidance, not a datasheet thermal rating.
Avoid choosing a substitute from the core name or DMIPS rating alone. A genuine drop-in decision requires the same 169-UFBGA geometry, compatible ball functions, equivalent supply and I/O constraints, required memory, and matching USB, DFSD, LCD, AES, and PKA resources. Also verify boot configuration, firmware migration needs, temperature grade, packing, and date-code policy. No verified external drop-in equivalent was supplied for this highly integrated MCU.
