STM32L496VGY6TR Overview
An ARM Cortex-M4 microcontroller is a 32-bit RISC processor core designed for embedded applications, featuring low power consumption, deterministic interrupt response, and optional single-precision floating-point unit (FPU). The M4 sits within the broader Cortex-M family hierarchy: Cortex-M0/M3/M4 -> ARMv7-M architecture -> 32-bit MCU -> embedded processor -> semiconductor. The STM32L4 series specifically targets ultra-low-power applications, balancing processing performance with energy efficiency through multiple low-power modes including Shutdown at 25 nA.
Key differentiating features include 1 MB flash, 320 KB SRAM, integrated SMPS step-down converter for dynamic voltage scaling, USB OTG FS, MIPI-DSI or parallel LCD interface support, two 12-bit ADCs at 5 Msps, two 12-bit DACs, DFSDM for audio/sensor applications, AES-256 and Hash accelerators, and the standard STM32 ecosystem (HAL/LL libraries, STM32CubeMX, IDE support). The WLCSP-100 package enables compact wearable and IoT designs where PCB area is critical.
The Cortex-M4F core includes a single-precision FPU that accelerates DSP operations and floating-point math. The internal SMPS regulator improves efficiency over the traditional LDO regulator approach during active mode, enabling higher performance at lower power. The device supports multiple low-power modes (Stop, Standby, Shutdown) with the Shutdown mode consuming only 25 nA for battery-backed IoT endpoints.
Typical applications include wearable fitness trackers, portable medical sensors, industrial IoT sensor nodes, USB-C powered accessories, LCD-based HMI panels, smart home sensor hubs, and audio interfaces leveraging the digital microphone support. The combination of USB OTG, LCD, and ultra-low power makes it particularly suited for battery-powered consumer and medical devices.
When designing with this device, verify that the WLCSP-100 footprint matches your PCB capability (WLCSP requires advanced PCB process for routing and inspection). For prototypes or hand-assembly, consider the LQFP-64 or UFBGA-169 variants of the STM32L496 family instead. Provide a stable VDD and consider the SMPS inductor selection per ST application note AN4621.

Key Differentiators
- WLCSP-100 footprint enables smallest wearable PCB (vs STM32L496VGT6 (LQFP-100))
- Integrated SMPS regulator improves active power efficiency (vs STM32L451VCT6 (LDO-only regulator))
- 1 MB flash and 320 KB SRAM exceed most L4 competitors (vs STM32L451VCT6 (256 KB flash, 160 KB SRAM))
Design Notes
Estimated: The STM32L496VGY6TR in WLCSP-100 has a theta_JA of approximately 35-40 C/W. At maximum 80 MHz active mode with full peripheral activity, total power dissipation remains below 200 mW, yielding a junction temperature rise of 7-8 C above ambient - well within the 85 C operating limit. For designs in enclosed wearable enclosures with limited airflow, monitor junction temperature under realistic active-mode duty cycles.
WLCSP-100 requires advanced PCB fabrication with micro vias, fine-line/spacing (typically 3 mil/3 mil or smaller), and ENIG or OSP surface finish. Per IPC-7093 design guidelines, escape routing through the inner rows requires high-density interconnect (HDI) stackups. For hand-assembled prototypes or low-volume runs, consider the LQFP-100 variant STM32L496VGT6 to avoid assembly rework challenges.
The integrated SMPS step-down regulator requires a small external inductor (typically 4.7-10 uH, 0806 size). Per ST application note AN4621, place the inductor and bypass capacitors within 5 mm of the SMPS pins to minimize EMI. The SMPS efficiency is typically 85-90 percent at typical loads, vs 65-70 percent for the LDO-only mode, providing meaningful active-mode battery life improvement.
Do not exceed 3.6 V on any VDD pin. The BOOT0 pin must be properly biased for normal flash boot; floating BOOT0 can cause the MCU to enter system memory bootloader unintentionally. For USB OTG, the VBUS sense pin requires a 5V-tolerant configuration; consult reference manual RM0351 for the proper GPIO alternate-function mapping. The HSE crystal oscillator load capacitance must match the crystal specification, not just the IC's internal load cap.
Keep the analog supply VDDA and its decoupling capacitor (100 nF + 1 uF parallel) within 5 mm of the VDDA pin to minimize ADC noise. The reference voltage pin VREF+ requires its own 100 nF + 1 uF capacitor pair for ADC accuracy. Route high-speed USB D+/D- as a 90-ohm differential pair with ground reference on the same layer, per USB 2.0 specification. Place the RTC crystal (32.768K) close to the OSC32_IN/OSC32_OUT pins with grounded guard traces.
Compliance Information
