Product details
Overview
STM32L496VGT6 from STMicroelectronics is an ultra-low-power Arm® Cortex®-M4 32-bit MCU with FPU, delivering 100 DMIPS at 80 MHz, featuring 1 MB flash, 320 KB SRAM, USB OTG FS, hardware SHA-256 acceleration, and integrated SMPS support. It operates across -40 °C to 125 °C, achieves 37 µA/MHz in SMPS-run mode, and supports batch acquisition mode (BAM) for sensor hub applications in battery-powered medical wearables.
For engineers reviewing the STM32L496VGT6 datasheet, STM32L496VGT6 pinout, STM32L496VGT6 application, or STM32L496VGT6 equivalent, key selection criteria include its dual-bank flash with read-while-write capability, 2.57 µA Stop 2 mode current, Chrom-ART Accelerator™ for GUI rendering, 3× 12-bit ADCs (5 Msps), and 2× CAN 2.0B interfaces for industrial edge node connectivity.
Technical Context
The device integrates an Adaptive Real-time Accelerator (ART) enabling zero-wait-state execution from flash memory, and a multi-AHB interconnect matrix supporting concurrent peripheral access without bus contention. Its FlexPowerControl architecture implements seven low-power modes-including Shutdown (25 nA), Standby with RTC (426 nA), and Stop 2 (2.57 µA)-with 5 wakeup pins and 5 µs wake-up latency.
It features three independent PLLs (system, USB, audio), dual-flash QUADSPI interface, external memory controller for NOR/PSRAM/NAND, and dedicated peripherals including DCMI (32 MHz B&W), DFSDM (4 digital filters), and LCD controller (8×40 segment drive). The analog subsystem includes 2× OPAMPs with PGA, 2× ultra-low-power comparators, and hardware oversampling up to 16-bit resolution.

FAQ
What is the maximum operating temperature range for STM32L496VGT6?
The STM32L496VGT6 is qualified for industrial operation from -40 °C to +125 °C ambient temperature, validated per AEC-Q100 stress test conditions. This rating applies to all LQFP100 variants and is confirmed in Section 6.3.1 of DS11585 Rev 20, enabling deployment in under-hood automotive modules and motor-drive control units.
Does STM32L496VGT6 support external SMPS control, and how is it implemented?
Yes-it provides dedicated VDD12 and VDD12_IO pins to interface with external switching regulators like the STMP2152. The MCU monitors VDD12 voltage and controls SMPS enable/disable via PWR_CR3 register bits, allowing dynamic transition between LDO and SMPS modes to achieve 37 µA/MHz run efficiency, as measured in Table 27 of the datasheet.
Can STM32L496VGT6 execute code from external QUADSPI flash memory?
No-the QUADSPI interface supports only memory-mapped read access (XIP) for data; instruction fetch is not supported. Code execution must occur from internal flash or SRAM. External QUADSPI is used for firmware storage, asset loading, or data logging, with DMA-assisted transfers to internal buffers as documented in Section 3.41.
How many independent ADC instances does STM32L496VGT6 integrate, and what is their maximum aggregate sampling rate?
It integrates three independent 12-bit ADCs (ADC1, ADC2, ADC3), each capable of 5 Msps in interleaved mode. With hardware oversampling enabled, effective resolution reaches 16-bit at 125 kSPS per ADC. Aggregate throughput across all three is 15 Msps when synchronized via timer-triggered simultaneous sampling, as specified in Section 3.17 and Table 6.3.18.
