STM32L475VGT6 - 1MB Flash Cortex-M4 MCU, 100-LQFP | STMicroelectronics
MPN: STM32L475VGT6 ✓ פעילSTM32L475VGT6 סקירה
A microcontroller (MCU) is a single-chip integrated circuit containing a processor core, program/data memory, and programmable peripherals that govern a specific embedded function. The STM32L475VGT6 is a member of the STM32L4 ultra-low-power family, which sits within the broader STM32 32-bit MCU portfolio and is engineered around ST's 110 nm ultra-low-leakage process with adaptive real-time (ART) accelerator. The Cortex-M4 core implements the ARMv7-M architecture with single-precision FPU and DSP extensions, making the part a member of the ARM Cortex-M family that is hierarchically classed as an embedded microcontroller -> 32-bit MCU -> semiconductor IC.
Key features include a wide 1.71 V to 3.6 V supply range, batch-collecting 12-bit 5 Msps ADC, two 12-bit DACs, two op-amps, two comparators, USB 2.0 OTG full-speed (with internal PHY), CAN 2.0B, SDMMC, SAI, DFSDM, multiple timers, and a true random number generator (TRNG) for security. Seven main low-power modes (Low-power Run, Sleep, Low-power Sleep, Stop 0/1/2, Standby, Shutdown) bring the typical Stop-mode current down to the microampere range and Standby/Shutdown to the nanoampere range, enabling multi-year battery life when paired with an energy-aware application design.
The architecture combines the Cortex-M4 DSP+FPUs with ST's ART Accelerator (instruction cache + pre-fetch) and an MPU, allowing sustained 100 DMIPS performance while maintaining ultra-low dynamic power. An embedded voltage regulator supports dynamic voltage scaling through the PDR1 (power-down) and LP regulator paths, decoupling core voltage from the external supply.
Typical applications include wearable fitness/health monitors, smart-metering and home/building automation nodes, industrial sensor hubs, medical point-of-care devices, low-power wireless IoT gateways, asset trackers, and USB-powered human-interface peripherals. The integrated USB OTG FS removes the need for an external PHY in many HID/CDC designs.
When designing with the STM32L475VGT6, follow the reference manual's decoupling and layout guidance (one 100 nF per VDD pair, one bulk 4.7 uF on the regulator input) and place the HSE crystal traces within the documented loading and guard-band limits. Selecting the right low-power pair must also consider whether the application can tolerate the wake-up latency of Stop 2 / Standby modes versus the higher autonomy of Low-power Run.

Wearable Health & Fitness Monitor
The STM32L475VGT6 fits wearable health-and-fitness monitors because its Cortex-M4F DSP+FPU accelerates heart-rate, SpO2, and motion-sensor DSP pipelines while its ultra-low-power modes extend battery life. Stop 2 mode draws microampere-range quiescent current, allowing multi-week runtimes on a small Li-Po battery. The 12-bit 5 Msps ADC pairs with on-chip op-amps to condition bioimpedance and PPG signals without external analog front-ends. USB OTG FS with integrated PHY simplifies charging/CDC data synchronization with no external ULPI device.

מומלץ
Smart Metering & Energy Harvesting Node
The STM32L475VGT6 fits smart-metering and energy-harvesting nodes because its 1.71-3.6 V supply range accepts direct output from small solar/PEM cells and its nanoampere Standby/Shutdown modes preserve battery during long idle windows. The Cortex-M4F runs metering DSP (RMS, harmonic analysis) at 80 MHz with 100 DMIPS headroom, and the SDMMC plus DFSDM peripherals interface to external metrology ASICs. Recommended companions: STMicroelectronics STPMIC1 power management IC, STM32L496RGT6 upgrade option with more SRAM.
מומלץ
Industrial Sensor Hub with USB-C
The STM32L475VGT6 fits industrial sensor hubs because its CAN 2.0B interface plus USB OTG FS provide both industrial bus connectivity and a USB-C host/device port for local HMI. Three 12-bit 5 Msps ADCs and two on-chip op-amps support multi-sensor analog front-ends without external amplifiers. The wide 1.71-3.6 V supply simplifies 24 V industrial-rail step-down to a single 3.3 V rail. Recommended companions: STMicroelectronics STM32F105RCT6 CAN bridge, STM32L073RZ for cost-down sensor-node designs.

The two 12-bit DACs and two on-chip op-amps condition analog front-end signals, while the SAI peripheral drives audio prompts or MEMS microphones. The TRNG provides the entropy source needed for authenticated firmware updates on medical hardware. Recommended companions: STMicroelectronics STM32H735IIT6 high-performance option, STM32L4R9ZIT6 for designs needing external SDRAM.
מומלץ
Low-Power IoT Gateway / Asset Tracker
The STM32L475VGT6 fits low-power IoT gateways and asset trackers because its USB OTG FS plus CAN, SDMMC, and SAI allow multiple wireless modules (LoRa, BLE, sub-GHz) to be hosted on a single MCU. Stop 2 mode draws microampere-level quiescent current when no events are pending, and the wide 1.71-3.6 V input tolerates battery droop during cold-temperature transients. Recommended companions: STMicroelectronics STM32MP135DAC3 for Linux-capable gateways, STM32F103VBT6 cost-down auxiliary.
מומלץ
Battery-Powered HMI / Keyboard
The STM32L475VGT6 fits battery-powered human-interface devices such as wireless keyboards, game controllers, and presenters because its low-power modes plus USB OTG FS (with integrated PHY) support both wireless 2.4 GHz dongles and USB-C wired modes. The 80 MHz Cortex-M4F runs HID report parsing and LED-matrix drivers in real time without external logic. Recommended companions: STMicroelectronics STM32G071G8U6 for ultra-low-cost wired-only HMI, STM32L051C8T3 for cost-sensitive button-only designs.

הערות תכנון
Place one 100 nF decoupling capacitor as close as possible to each VDD pin and one bulk 4.7 uF ceramic at the regulator input (VDD/VDDA pair). According to the STM32L475xx datasheet power-supply section, using shared decoupling for the VDD/VDDA pins can couple digital switching transients into the analog reference and degrade ADC SNR by 4-6 dB. Use separate ferrite-bead-isolated rails for VDDA in metering and audio designs.
Route the HSE crystal traces within 7 mm of OSC_IN/OSC_OUT and keep the loading capacitors within the datasheet-specified CL range (typically 6-10 pF on STM32L4). Maintain a ground guard ring around the crystal and avoid routing signal traces under or near it; violating these rules typically causes HSE crystal-startup failures or 0.5-1% frequency error at temperature. Estimated crystal trace parasitic of 5 pF should be subtracted from the load-capacitor budget.
When migrating Stop 2 to Stop 0 for faster wake-up latency, the SDMMC, SAI, and DFSDM peripherals lose their configuration state and must be reinitialized in the wake-up ISR. Estimated wake-up time from Stop 2 is around 5-10 us vs 1 us from Stop 0; choose Stop 0 only when the application cannot tolerate the longer wake-up latency. Also note: Shutdown mode removes RTC backup register retention unless VBAT is held.
At 80 MHz active and 1.71-3.6 V supply, typical active current is approximately 10 mA / MHz giving 800 mW maximum at full CPU load on the 100-LQFP. The LQFP-100 has theta_JA around 50 C/W on a 4-layer JEDEC test board, so a 800 mW full-load dissipation yields about 40 C junction temperature rise above ambient; no heatsink is required for typical IoT workloads. Verify thermal rise at ambient 85 C to confirm Tjunction stays below 110 C.
