STM32L486QGI6 - 80MHz Cortex-M4 1MB MCU | STMicroelectronics
部品番号: STM32L486QGI6 ✓ 生産中STM32L486QGI6 概要
A microcontroller is a programmable semiconductor that combines a processor core, embedded Flash, RAM, peripherals, and communication interfaces into one device. The STM32L4 family belongs to the broader embedded-processing hierarchy: microcontroller -> 32-bit RISC microcontroller -> Arm Cortex-M microcontroller -> STM32L4 series. This integration allows an equipment designer to execute firmware, acquire data, control peripherals, and communicate with external systems without using separate memory and logic devices.
The STM32L486QGI6 combines an Arm Cortex-M4 processor with an FPU, according to the verified Mouser product listing. Its 1 MB Flash configuration provides substantially more program storage than smaller STM32L4 variants and is suitable for complex control firmware, protocol stacks, data acquisition routines, and embedded user interfaces. The manufacturer identifies the STM32L486xx family as an ultra-low-power MCU platform designed for applications where energy efficiency and processing capability are both important.
Verified distributor information identifies LCD support, USB OTG, and AES functionality for this device family. These capabilities make the MCU relevant to compact industrial controllers, USB-connected sensors, secure access terminals, and embedded human-machine-interface systems. The target order code is supplied in a 132-UFBGA tray package according to Arrow Electronics, while the exact memory, voltage, and temperature details not present in the verified source extracts remain designated for additional datasheet confirmation.
The principal design consideration is package-level planning. A 132-UFBGA device requires a dense multilayer PCB, fine-pitch ball placement, controlled escape routing, and assembly capability suited to BGA packages. Designers must follow STMicroelectronics land-pattern, routing, solder-mask, and thermal guidance rather than adapting a generic QFN layout. Although the 7 x 7 mm package is compact, its 132 balls create a substantially more demanding manufacturing process than a leaded package.
This product page consolidates verified manufacturer and distributor information into a technical sourcing reference. It combines the exact 80 MHz, 1 MB Flash, 132-UFBGA, voltage, packaging, and price attributes with drop-in-family alternatives, interface-focused applications, and package-aware engineering guidance that should be checked against the complete manufacturer datasheet before schematic release.

主な用途
STM32L486QGI6 の用途: 6 件s: USB-Conditioned Sensor Controller, Industrial Data-Acquisition Module, Secure Access-Control Terminal, USB-Powered Portable Instrument, Compact Human-Machine Interface, Edge IoT Gateway Controller.
USB-Conditioned Sensor Controller
The STM32L486QGI6 fits a compact USB-connected sensor controller because it combines an 80 MHz Arm Cortex-M4 core, 1 MB of Flash, USB OTG capability, and AES support in a 132-UFBGA package. The core can execute acquisition, filtering, and protocol software while the security peripheral supports protected data-transfer workloads. Its verified 1.8 V, 2.5 V, and 3.3 V operating options also align with mixed-signal sensor designs. The 7 x 7 mm package helps reduce board area, but the 132-ball layout requires fine-pitch routing and careful USB differential-pair layout. Firmware, transceiver requirements, power sequencing, and the exact USB electrical characteristics should be verified against the complete manufacturer datasheet before production release.
おすすめ
Industrial Data-Acquisition Module
The STM32L486QGI6 is suitable for an industrial data-acquisition module that must combine local control, data buffering, and communications. Its Arm Cortex-M4 processor operates at up to 80 MHz, providing enough performance for sampling control and communication tasks, while the verified 1 MB Flash capacity accommodates firmware, calibration tables, and protocol components. LCD support can present operating status or measurement data locally, and AES can support secure configuration or data-handling functions. The compact 132-UFBGA package saves board area compared with leaded packages. Design effort should focus on analog isolation, precision routing, thermal behavior of the complete module, and a multilayer PCB capable of supporting the 132-ball land pattern.
おすすめ
Secure Access-Control Terminal
The STM32L486QGI6 can serve in a secure access-control terminal where an 80 MHz Cortex-M4 core manages credential processing, local user-interface updates, and communications. The verified feature set includes AES, which is relevant to encrypted credential or communication workflows, while 1 MB of Flash provides room for a larger embedded application than many small-footprint MCUs. LCD support also enables a compact display for status and operator prompts. The device should be evaluated for a package with 132 UFBGA balls only after confirming assembly yield, inspection requirements, thermal performance, and the availability of secure programming and lifecycle-management processes in the relevant deployment environment.
おすすめ
USB-Powered Portable Instrument
The STM32L486QGI6 is appropriate for a USB-powered portable instrument that needs local measurement, display control, and data transfer in a small enclosure. Its verified low-voltage options of 1.8 V, 2.5 V, and 3.3 V suit systems powered from regulated USB rails, while USB OTG enables a direct digital interface. The 1 MB Flash capacity supports instrument firmware, calibration data, and communication stacks, and the 80 MHz Cortex-M4 core provides responsive control. A practical design must include careful input-capacitance planning, low-noise power distribution, USB signal routing, and thermal analysis for the compact assembly. Battery-current behavior cannot be quantified from the supplied extracts and should be checked in the complete low-power documentation.
おすすめ
Compact Human-Machine Interface
The STM32L486QGI6 fits a compact LCD-based human-machine interface because the verified product information identifies LCD support and an FPU-equipped 80 MHz Arm Cortex-M4 core. It can drive display updates, process operator input, and execute application logic while the 1 MB Flash stores firmware and interface resources. The 132-UFBGA package allows a compact controller board, but its 7 x 7 mm body and 132 balls require laser-drilled vias, fine-pitch escape routing, and careful power-plane geometry. Display timing, available LCD peripheral instances, pin multiplexing, display voltage requirements, and EMI performance must be checked against the exact package pin map before schematic sign-off.
おすすめ
Edge IoT Gateway Controller
The STM32L486QGI6 can support an edge IoT controller that gathers sensor information, applies local rules, and forwards data through a wired or USB communication interface. Its 80 MHz Cortex-M4 core handles protocol processing and control tasks, and 1 MB of Flash provides sufficient storage for a substantial firmware image. USB OTG, AES, and LCD capabilities broaden the design options for local diagnostics and secure connectivity. Because the verified results do not specify Ethernet MAC or radio functionality, an external network or radio component may be required. The controller layout should preserve short return paths, isolate analog and digital sections, provide robust decoupling, and use the exact 132-UFBGA assembly land pattern for reliable production yield.

設計ノート
Treat the STM32L486QGI6 as a fine-pitch BGA layout rather than a generic QFN. Use the exact 132-UFBGA land pattern and ball map from the STMicroelectronics package documentation, and plan escape routing before placing the MCU. A multilayer PCB with adequate via density is generally needed to connect the compact 7 x 7 mm device to external components. Validate solder-paste volume, mask dams, component spacing, and assembly inspection requirements because the verified sources do not provide a complete assembly process specification.
Decouple each applicable supply rail directly at the corresponding package balls and provide the manufacturer-recommended bulk capacitance close to the device. The verified operating-voltage options are 1.8 V, 2.5 V, and 3.3 V, but the exact supply rails, sequencing rules, current limits, and capacitor values are absent from the extracts. Those values must be taken from the complete datasheet before schematic release; estimating them from the target MCU's general-purpose 3.3 V usage can produce unstable startup or analog-performance problems.
Preserve USB signal integrity by routing the verified USB OTG interface as a controlled-impedance differential pair over a continuous reference plane, with symmetric vias and minimal stubs. Keep switching supplies, high-current loads, and fast digital edges away from sensitive analog and communication routes. Although the verified material does not specify the complete USB electrical interface or all package ball functions, layout should still be reviewed against the final pin table, USB implementation guidance, and the actual external transceiver or connector.
A matching package name does not by itself prove that an STM32L4 replacement is a functional drop-in. The alternative list is restricted to the same-brand QGI6 family, but differences in Flash, RAM, USB OTG implementation, LCD resources, AES behavior, clocking, peripherals, and software support still require verification. Before substitution, compare the complete order-code tables, pin functions, electrical characteristics, firmware startup files, drivers, and security provisions. Do not approve a replacement based only on its 132-UFBGA footprint.
コンプライアンス情報
The supplied verified results do not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. These fields remain unknown rather than being inferred from the manufacturer or distributor listings.
