Product details
Overview
STM32L496RGT6TR 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 current and real-time audio processing.
For engineers reviewing the STM32L496RGT6TR datasheet, STM32L496RGT6TR pinout, STM32L496RGT6TR application, or STM32L496RGT6TR equivalent, key selection criteria include its 2.57 µA Stop 2 mode, dual-bank flash for seamless firmware updates, Chrom-ART Accelerator for GUI rendering, and dual CAN 2.0B interfaces for industrial fieldbus integration.
Technical Context
The device implements an Adaptive Real-Time (ART) Accelerator enabling zero-wait-state execution from flash at 80 MHz, paired with a memory protection unit (MPU) and interconnect matrix for deterministic peripheral arbitration. Its power architecture integrates three voltage regulators - LDO, SMPS, and low-power LDO - supporting dynamic voltage scaling across seven low-power modes.
Peripherals are organized via a multi-AHB bus matrix with firewall-protected memory regions; analog subsystems (3× 12-bit ADCs, 2× DACs, 2× op-amps, 2× comparators) operate with independent supply domains down to 1.08 V, while the DCMI supports 32 MHz monochrome or 10 MHz color camera input.

FAQ
What is the maximum operating frequency and associated performance metric?
The STM32L496RGT6TR operates at up to 80 MHz with an Adaptive Real-Time Accelerator enabling zero-wait-state flash execution. Its performance is quantified at 100 DMIPS (Dhrystone 2.1) and 273.55 CoreMark®, achieving 3.42 CoreMark/MHz. This delivers deterministic real-time response for motor control loops and audio sample processing without external memory bottlenecks.
How does the FlexPowerControl architecture reduce power consumption in active mode?
FlexPowerControl allows dynamic selection between internal LDO and external SMPS regulation. In SMPS mode, active current drops to 37 µA/MHz at 3.3 V - a 59% reduction versus 91 µA/MHz in LDO mode. This is achieved by configuring the PWR_CR3 register to enable SMPS and setting appropriate voltage scaling (VOS1/VOS0 bits), directly lowering system-level power draw during sustained computation.
Which low-power modes support RTC operation and what are their current draws?
Standby mode with RTC consumes 426 nA, and Stop 2 mode with RTC draws 2.86 µA. Both retain RTC calendar, alarms, and 32 × 32-bit backup registers. Standby mode powers down all clocks except LSE-driven RTC, while Stop 2 maintains HSI16 or MSI for faster wakeup (≤5 µs). These modes are selected via PWR_CR1 register bits (LPMS[2:0]) and require proper clock configuration in RCC_CSR.
Does the device support external memory interfaces, and if so, which types?
Yes - the STM32L496RGT6TR integrates a Flexible Static Memory Controller (FSMC) supporting SRAM, PSRAM, NOR, and NAND memories, plus a dual-flash QUADSPI interface for XIP-capable serial flash. The FSMC uses dedicated address/data bus pins (e.g., PD0–PD15, PE7–PE15) and supports wait-state programmability for timing compliance with diverse memory vendors' specifications.
