Product details
Overview
STM32L496VGY6TR 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 acceleration, and integrated SMPS support. It targets battery-powered industrial sensors, portable medical devices, and energy-harvesting IoT endpoints requiring sub-µA standby operation and real-time audio processing.
For engineers reviewing the STM32L496VGY6TR datasheet, STM32L496VGY6TR pinout, STM32L496VGY6TR application, or STM32L496VGY6TR equivalent, key selection criteria include its 2.57 µA Stop 2 mode current, dual-bank read-while-write flash, Chrom-ART Accelerator for GUI rendering, and dual CAN 2.0B interfaces for robust fieldbus connectivity.
Technical Context
The device integrates an Adaptive Real-Time (ART) Accelerator enabling zero-wait-state execution from flash at 80 MHz, alongside a multi-layer AHB bus matrix for concurrent peripheral access. Its FlexPowerControl architecture supports seven low-power modes-including 25 nA Shutdown and 426 nA Standby with RTC-managed by a dedicated power control block with brownout reset in all active modes.
Peripherals are routed via an interconnect matrix supporting simultaneous DMA transfers across 14 channels, while clock management includes three PLLs (system, USB, audio), internal 48 MHz recovery, and auto-trimmed multispeed oscillator (±0.25%). Analog subsystems feature 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.

FAQ
What is the maximum operating frequency and associated DMIPS rating?
The STM32L496VGY6TR operates at up to 80 MHz with an ART Accelerator enabled, delivering 100 DMIPS (1.25 DMIPS/MHz). This performance level is validated per Dhrystone 2.1 benchmark and sustained across voltage ranges from 1.71 V to 3.6 V, with no wait states required for flash execution.
Does this MCU support external SMPS, and how does it affect power consumption?
Yes, the STM32L496VGY6TR supports external SMPS via the VDD12 pin, enabling core supply at 1.1 V. In this configuration, active-mode current drops to 37 µA/MHz-nearly 60% lower than the 91 µA/MHz achieved with internal LDO regulation-making it ideal for long-life battery applications.
Which low-power modes retain RTC functionality, and what is the typical current draw?
Standby mode with RTC enabled draws 426 nA, while Stop 2 mode with RTC consumes 2.86 µA. Both modes preserve the hardware calendar, alarms, and 32×32-bit backup registers. RTC operation remains fully functional with VBAT supply, allowing timekeeping during main power removal.
What peripheral interfaces are available for audio processing applications?
The MCU integrates two Serial Audio Interfaces (SAI) supporting I²S, PCM, and SPDIF protocols, plus a dedicated audio PLL for jitter-free clock generation. Combined with two 12-bit DACs and hardware-accelerated audio sample rate conversion, it supports stereo playback and microphone array preprocessing in portable audio endpoints.
