STM32L496QEI6 Descripción general
An ultra-low-power microcontroller is a semiconductor device designed to complete control, sensing, communications, and data-processing tasks while minimizing energy consumption. The STM32L496 belongs to the STM32L4 family of low-power microcontrollers, combining a high-performance Arm Cortex-M4 core with peripherals for security, connectivity, analog measurement, timing, and human-machine-interface functions. This places it within the embedded-processing hierarchy: microcontroller, 32-bit RISC processor, semiconductor, and embedded-control platform.
Key verified features include an 80 MHz Arm Cortex-M4 core, 512 KB Flash, a 132-UFBGA package, and ultra-low-power positioning. Distributor listings also identify USB OTG and LCD support, while the STMicroelectronics product family page describes the STM32L496xx devices as ultra-low-power Cortex-M4 MCUs operating up to 80 MHz. These features make the device suitable when an engineer needs substantial processing performance without moving to a larger general-purpose MCU architecture.
The STM32L496QEI6 is manufactured in a 132-UFBGA 7 x 7 mm package, requiring careful PCB layout, fine-pitch routing, and assembly validation. Unlike a simple through-hole microcontroller, its dense package can reduce board area but increases sensitivity to solderability, via placement, thermal performance, and manufacturing capability. A complete design should follow the manufacturer pinout, recommended land pattern, decoupling strategy, and PCB guidelines in the STM32L496 documentation.
Typical applications include industrial control and automation, USB-connected data acquisition, low-power sensor nodes, LCD-equipped user interfaces, building and energy systems, and compact embedded products. For battery- or energy-harvesting designs, the STM32L496 family is attractive because its low-power architecture can reduce the energy required between task wake-ups. The exact low-power current figures and peripheral specifications should be confirmed in the manufacturer datasheet before final design sign-off.
A key design consideration is package and power-rail integrity. Place all required decoupling capacitors close to the device supply pins, route sensitive signals away from high-current switching paths, and preserve the manufacturer-defined exposed-pad and thermal layout. Verify pin multiplexing, alternate-function conflicts, clock configuration, USB requirements, and firmware support before releasing a PCB for production. This page combines verified distributor information with engineering guidance intended to make the STM32L496QEI6 selection process more transparent.

Aplicaciones típicas
STM32L496QEI6 es adecuado para 6 aplicacións: USB Connected Data Acquisition, Industrial Control Module, Low-Power Sensor Node, LCD User Interface, Building Energy Controller, Compact Motor Control.
USB Connected Data Acquisition
The STM32L496QEI6 fits compact USB data-acquisition and configuration products because verified distributor data identifies USB OTG alongside an 80 MHz Arm Cortex-M4 core. A designer can place sensing, control, and communication firmware in one low-power MCU while using the 132-UFBGA package to reduce board area. The USB interface still needs careful power sequencing, connector protection, controlled-impedance routing, and firmware support. Compared with a larger host processor, the STM32 approach can simplify the control path, but USB speed, current consumption, and transceiver requirements must be confirmed from the manufacturer data.
Recomendado
Industrial Control Module
The STM32L496QEI6 is suitable for compact industrial control modules that combine real-time timing, communications, and low-power operation. Its 80 MHz Cortex-M4 core provides processing headroom for control loops, while the STM32L4 family positioning supports energy-conscious designs. The 132-UFBGA package can reduce module size, although industrial products must also account for temperature, vibration, supply transients, isolation, and long-term component availability. Firmware partitioning and diagnostic functions should be validated against the actual actuator and sensor interfaces rather than inferred from the MCU core frequency.
Recomendado
Low-Power Sensor Node
The STM32L496QEI6 fits low-power sensor nodes that periodically measure, process, and transmit data. Its 80 MHz Cortex-M4 core can execute filtering and protocol handling while the STM32L4 family’s ultra-low-power positioning helps manage energy between wake events. The 512 KB Flash capacity provides room for application code, but the supplied data does not specify RAM, sleep current, or wake-up timing, so those values must be checked before sizing a battery. Board leakage, sensor self-heating, radio duty cycle, and the selected operating mode usually determine the final battery life as much as the MCU does.
Recomendado
LCD User Interface
The STM32L496QEI6 can be evaluated for compact LCD-equipped user interfaces because verified distributor data lists LCD support. A single MCU can manage display updates, front-panel controls, local status indicators, and communications in a small embedded product. The 132-UFBGA 7 x 7 mm package helps reduce board area, but the display interface voltage, timing, and panel requirements are not specified in the supplied data and must be confirmed in the manufacturer documentation. Designers should also plan contrast, backlight, touchscreen, ESD, and human-factor requirements at the product level rather than treating the LCD feature as a complete display solution.
Recomendado
Building Energy Controller
The STM32L496QEI6 is appropriate for building-energy controllers that coordinate sensors, relays, displays, and communications while operating between maintenance intervals. Its Cortex-M4 processing capability can support protocol handling and local control logic, and the STM32L4 family’s low-power focus can help reduce standby demand. The dense UFBGA package is appropriate for a compact controller board, although industrial environmental requirements and surge protection must be designed around the enclosure and wiring. Relay outputs, sensor inputs, and external power conversion may dominate system accuracy and energy use, so MCU selection should be validated at the full system level.
Recomendado
Compact Motor Control
The STM32L496QEI6 can serve as the control MCU in compact motor-control products where real-time processing, timer resources, and low-power operation are important. The 80 MHz Arm Cortex-M4 core can execute control algorithms and coordinate input capture, PWM, communications, and protection logic. The supplied data does not specify timer channels, PWM frequency, ADC characteristics, or motor-driver interfaces, so those requirements must be checked before committing to the device. Power-stage transients, thermal conditions, encoder resolution, and safe shutdown behavior are more important than the package name alone.

Notas de diseño
Treat the 132-UFBGA package as a fine-pitch assembly constraint. Follow the manufacturer’s land pattern, ball assignment, exposed-pad recommendation, solder-mask, paste, and reflow profiles rather than adapting a generic QFN layout. Escape all power, ground, clock, and high-speed signal balls in the first routing pass, and keep decoupling paths short. Because the supplied data does not include the complete pinout, verify every ball and power connection against the current STMicroelectronics package documentation before fabrication.
Design the supply network around the exact STM32L496QEI6 operating voltage, current, and sequencing requirements from the manufacturer documentation. Place local bulk and high-frequency decoupling capacitors close to the relevant power balls, use a low-impedance ground reference, and isolate noisy switching converters from sensitive analog or USB routing. The verified material identifies USB OTG but does not provide regulator current limits or USB bus-power requirements, so power budget calculations must use the official electrical characteristics.
Validate USB, clock, and other high-speed routes with the actual stack-up and assembly constraints. Keep USB differential routing continuous and away from switching nodes, provide the required connector and ESD protection, and maintain return-path continuity across the 132-UFBGA escape region. The supplied data does not specify USB speed or transceiver details, so board-level compliance should be established from the exact STMicroelectronics interface requirements rather than inferred from the phrase USB OTG.
Información de cumplimiento
The supplied verified data does not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. Confirm these attributes from the current STMicroelectronics product documentation and supplier declarations.
