STM32L496QGI3 - 80MHz 1MB Cortex-M4 MCU | STMicroelectronics
MPN: STM32L496QGI3 ✓ Hoạt độngSTM32L496QGI3 Tóm tắt
A microcontroller is a programmable system-on-chip that integrates a CPU core, memory, peripherals, and communication interfaces into one component. In the hierarchy, STM32L496QGI3 is an Arm Cortex-M4 MCU, an embedded microcontroller, and a semiconductor within the broader STM32L4 family. Its combination of processing performance, low-power modes, and extensive connectivity supports compact embedded systems.
Key features include an Arm Cortex-M4 processor with FPU, 100 DMIPS performance, 1 MB Flash, and 320 KB SRAM. The device also supports USB OTG FS, audio, HASH, and an external SMPS. Its operating supply range is 1.71 V to 3.6 V, while the documented temperature options span -40 °C to 85 °C, 105 °C, or 125 °C, depending on the ordering variant.
The STM32L496 architecture combines a high-performance 32-bit RISC core with low-power FlexPowerControl operating modes. Low-power behavior includes 320 nA in VBAT mode for the RTC and 32 x 32-bit backup registers, plus 25 nA shutdown consumption with five wakeup pins. These characteristics suit battery-operated and always-on products where standby current matters as much as active processing speed.
Typical uses include industrial control, USB-connected data acquisition, human-interface equipment, sensor hubs, portable instruments, and low-power embedded gateways. The USB OTG FS interface can simplify host or device connectivity, while the large memory footprint supports firmware, data buffering, and application logic. The external SMPS option is useful when system power architecture requires more flexibility than a fixed internal regulator arrangement.
For PCB design, use the manufacturer pin and package guidance for the 132-UFBGA land pattern, and verify ball assignments before routing. Decoupling, ground-plane continuity, and high-speed signal return paths are critical because a compact BGA package leaves limited routing space. Confirm the exact peripheral pin multiplexing, power sequencing, and exposed-pad connection from the manufacturer datasheet.
This product page combines verified distributor identification and manufacturer datasheet specifications with package, sourcing, and design context. It is intended to help engineers compare the STM32L496QGI3 with same-package alternatives and plan a compliant, thermally sound implementation without treating unrelated MCUs as drop-in replacements.

Ứng dụng tiêu biểu
STM32L496QGI3 phù hợp cho 6 Áp dụngs: USB-connected industrial data acquisition, Battery-powered sensor hubs, Portable medical and wellness interfaces, Human-interface and configuration panels, Low-power gateway and edge node, USB host peripheral and service tool.
USB-connected industrial data acquisition
The STM32L496QGI3 fits USB-connected data-acquisition and control systems that need an 80 MHz Cortex-M4 core, 1 MB Flash, 320 KB SRAM, and USB OTG FS in one MCU. It can buffer sensor data, execute local control logic, and expose measurements through a USB device or host interface. The 1.71 V to 3.6 V operating range supports integration with low-voltage industrial power trees, while 320 nA VBAT current and 25 nA shutdown current help preserve standby behavior when the enclosure is idle.
Được đề xuất
Battery-powered sensor hubs
STM32L496QGI3 is appropriate for battery-powered sensor hubs where low leakage can extend service between maintenance visits. Its documented 320 nA VBAT mode current supports RTC and backup-register retention, while 25 nA shutdown mode provides a deep-sleep option with five wakeup pins. The 80 MHz processor handles local filtering and event logic, and the 320 KB SRAM provides room for temporary measurement buffers. Power-budget calculations must still account for sensor leakage, radio activity, regulator efficiency, and wakeup-current peaks.
Được đề xuất
Portable medical and wellness interfaces
The STM32L496QGI3 can serve portable medical-adjacent, wellness, or diagnostic-interface products when low standby power and compact processing are priorities. Its Cortex-M4 FPU supports responsive control and signal handling, while USB OTG FS enables a compact connection to a host or service interface. The 132-UFBGA package reduces board area compared with larger leaded packages, but the compact footprint requires careful BGA layout, thermal management, and manufacturing inspection. Regulatory claims and medical certification must be established separately for the finished product.
Được đề xuất
Human-interface and configuration panels
STM32L496QGI3 is useful for human-interface equipment requiring responsive control, USB connectivity, and low idle consumption. The 80 MHz Cortex-M4 core can manage display updates, input scanning, communication tasks, and application state, while 1 MB Flash provides room for firmware and interface resources. A configurable low-power strategy can reduce energy use when the panel is idle, using the documented shutdown mode and five wakeup sources. Display drivers and touch controllers should be selected separately and validated against the exact package pin map.
Được đề xuất
Low-power gateway and edge node
STM32L496QGI3 can support low-power gateway and edge nodes that aggregate local sensor information before forwarding it through USB or another serial interface. Its 1 MB Flash and 320 KB SRAM provide a substantial embedded platform, while low-power modes are useful when traffic is intermittent. The external SMPS capability can support flexible system power architectures, provided the external components and sequencing are designed according to the manufacturer application information. Avoid assuming that the SMPS feature eliminates all analog or power-management design work.
Được đề xuất
USB host peripheral and service tool
STM32L496QGI3 is suitable for USB OTG FS host, service, and configuration tools that need more memory and processing capability than a basic eight-bit or low-density MCU. The Cortex-M4 core can run protocol handling, device enumeration, diagnostics, and local storage logic, while USB OTG FS provides the physical interface foundation. Board design must account for USB signal routing, connector protection, supply requirements, and firmware support for the intended host or device role. The verified data confirms USB OTG FS but does not provide host-negootiation timing values.

Ghi chú thiết kế
Design the 1.71 V to 3.6 V supply and all associated bypass paths around the manufacturer requirements. Estimated: if the MCU rail dissipation must be checked against a thermal design, calculate P = (VIN - VIO) x IOUT only after confirming the actual I/O voltage and load current. Because those operating values are not supplied, no numerical power estimate is asserted here. Keep the supply regulator's noise and transient response compatible with the USB, ADC, and other sensitive peripherals used in the design.
The 132-UFBGA 7 x 7 mm package requires a manufacturer-compatible land pattern and careful escape routing. Place decoupling capacitors close to their associated power balls, maintain short and symmetric routes where timing matters, and provide a solid ground reference. Do not infer ball assignments from the generic STM32L4 family diagram; verify the exact STM32L496QGI3 pin table and exposed-pad requirements in the official package documentation.
Separate sensitive analog and digital return paths where possible, even when the device is controlled digitally. Keep USB traces short, continuous, and referenced to an uninterrupted ground plane, and avoid routing high-current or switching-converter nodes beneath sensitive MCU balls. The exact placement and via strategy should follow the package drawing and the board stackup used by the fabricator. Validate signal integrity and power-integrity behavior with pre-compliance testing before production release.
Do not select a related STM32L496 ordering code solely because its family name and package appear similar. Check flash size, SRAM, USB implementation, temperature grade, clock limits, pin or ball mapping, peripheral multiplexing, and power requirements. The verified data does not establish complete equivalence for the listed alternatives, so any replacement should be approved through a formal firmware, hardware, and sourcing review.
