Product details

Overview

STM32L496QGI6 from STMicroelectronics is an ultra-low-power Arm® Cortex®-M4 32-bit MCU with FPU, operating up to 80 MHz (100 DMIPS), featuring 1 MB flash, 320 KB SRAM, USB OTG FS, hardware SHA-256 accelerator, and integrated SMPS support. It targets battery-powered IoT edge nodes, portable medical sensors, and energy-harvesting gateways requiring sub-µA standby operation and real-time audio processing.

For engineers reviewing the STM32L496QGI6 datasheet, STM32L496QGI6 pinout, STM32L496QGI6 application, or STM32L496QGI6 equivalent, key selection criteria include its 2.86 µA Stop 2 mode with RTC, dual-bank read-while-write flash, Chrom-ART Accelerator for GUI rendering, and dual CAN 2.0B interfaces for industrial fieldbus integration.

Technical Context

The device integrates an Adaptive Real-Time (ART) Accelerator enabling zero-wait-state execution from flash at 80 MHz, coupled with a memory protection unit (MPU) and interconnect matrix for deterministic peripheral arbitration. Its power architecture supports both internal LDO and external SMPS (achieving 37 µA/MHz run efficiency), with five low-power modes including Shutdown (25 nA) and Standby with RTC (426 nA).

Peripherals include two SAI interfaces for I²S/TDM audio streaming, four I²C FM+ ports (1 Mbit/s), six USART/LPUARTs with LIN/IrDA/ISO 7816 support, and a 14-channel DMA controller with dedicated channels for ADC, DAC, and DFSDM. The analog subsystem features three 12-bit ADCs (5 Msps), two 12-bit DACs, two op-amps with PGA, and two ultra-low-power comparators - all with independent supply domains.

Pinout & Package

STM32L496QGI6 uses a UFBGA132 (7 × 7 mm, 0.4 mm pitch) package with 112 user I/Os - 100 of which are 5 V-tolerant, and up to 14 support independent V_DDIO2 down to 1.08 V for interfacing with low-voltage peripherals.

Pin/Terminal	Circuit Role	Design Meaning
VDD, VSS	Main power supply and ground	Supports 1.71–3.6 V operation; decoupling required per STM32L4 layout guidelines to maintain SMPS stability.
VDDA, VSSA	Analog domain supply and ground	Must be filtered separately to ensure <1 LSB noise on 12-bit ADC/DAC conversions.
PA0–PA15, PB0–PB15, etc.	General-purpose I/Os	Configurable as GPIO, AF functions (e.g., USART1_TX on PA9), or event inputs; most tolerate 5 V even when VDD = 1.8 V.
PC13–PC15	RTC-related pins	PC13 = RTC_OUT, PC14/PC15 = LSE crystal oscillator - critical for calendar accuracy and tamper detection in security-critical logging.
PA11/PA12	USB OTG FS D+/D−	Dedicated full-speed USB transceiver with internal pull-ups - eliminates need for external USB PHY or termination resistors.
PD0/PD1	OSC_IN/OSC_OUT	4–48 MHz HSE crystal interface - used for high-precision timing in audio clock recovery or CAN bit-rate synchronization.

Key Features

Feature	Design Value
FlexPowerControl architecture	Enables 25 nA Shutdown mode with 5 wakeup pins - ideal for wake-on-event sensor hubs where microamp quiescent current is mandatory.

Dual-flash QUADSPI interface	Direct XIP support for external Octal/Quad SPI flash - expands code space beyond 1 MB while maintaining deterministic interrupt latency (<200 ns).
True Random Number Generator (RNG)	NIST SP800-90B compliant entropy source - satisfies cryptographic key generation requirements for TLS 1.2/1.3 and secure firmware signing.
External SMPS support	Integrated voltage supervisor and control logic for external DC-DC converter - achieves 37 µA/MHz run efficiency, critical for >5-year coin-cell operation.

Equivalent & Alternatives

The following parts are listed as comparable options for similar ultra-low-power MCU applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STM32L476RG	Same Cortex-M4 core, but 1 MB flash reduced to 1 MB (same), 320 KB SRAM reduced to 128 KB, no USB OTG FS, no SMPS support, no SAI.	Lacks audio interface and external SMPS control - unsuitable for battery-powered audio endpoints or high-efficiency power architectures.	Select only if USB/audio/SMPS are unnecessary and BOM cost reduction outweighs feature loss.
STM32U575ZIT6	Successor Cortex-M33 core, 2 MB flash, 786 KB SRAM, TrustZone, 1.4 µA Shutdown, but no SAI or DCMI; requires different toolchain and HAL.	Higher security and memory capacity, but lacks native audio peripherals - demands redesign for audio path and increases certification effort for medical use.	Choose for new designs prioritizing PSA Level 3 security and >10-year longevity, not for drop-in replacement.

Compared with STM32L476RG, STM32L496QGI6 delivers 2.5× more SRAM and integrated USB/SAI for audio-class applications; versus STM32U575ZIT6, it offers proven audio peripheral IP and simpler migration from legacy L4 designs, despite lower security certification level.

FAQ

What is the maximum operating temperature range for STM32L496QGI6?

The STM32L496QGI6 is qualified for industrial operation from –40 °C to +85 °C, with extended grade variants supporting –40 °C to +125 °C. This rating applies to all operating modes including Run, Stop, and Standby, and is validated per JEDEC JESD47 stress testing standards.

Does STM32L496QGI6 support external quad-SPI flash memory boot?

Yes - the device includes a dedicated QUADSPI interface that supports XIP (execute-in-place) from external Octal/Quad SPI flash. Boot mode selection is controlled via BOOT0/BOOT1 pins, and the ROM bootloader can load firmware images directly from QUADSPI memory into internal SRAM for execution.

How many independent power domains does STM32L496QGI6 provide for analog peripherals?

It provides three independent analog power domains: V_DDA/V_SSA for ADC/DAC/OPAMP/COMP, V_REF+/V_REF– for precise reference voltage, and V_DDIO2 for 14 I/Os configurable down to 1.08 V - enabling mixed-voltage sensor interfacing without external level shifters.

Can STM32L496QGI6 achieve USB device enumeration without external crystal?

Yes - the internal 48 MHz RC oscillator with clock recovery system (CRS) meets USB full-speed timing requirements (±0.25% accuracy). This eliminates the need for an external 48 MHz crystal, reducing BOM cost and PCB area while maintaining reliable USB enumeration in portable designs.
