Product details
Overview
STM32L496RGT6 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 HASH (SHA-256), 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 STM32L496RGT6 datasheet, STM32L496RGT6 pinout, STM32L496RGT6 application, or STM32L496RGT6 equivalent, key selection criteria include its 2.57 µA Stop 2 mode, dual-bank flash for read-while-write, 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 Accelerator (ART) 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 in SMPS run mode), with five low-power modes including Shutdown (25 nA) and Standby with RTC (426 nA).
Peripherals include three 12-bit ADCs (5 Msps, hardware oversampling to 16-bit), two 12-bit DACs, two op-amps with PGA, two ultra-low-power comparators, and dedicated DFSDM filters - all with independent supply domains for mixed-signal integrity. The dual SAI interfaces support I²S/TDM audio streaming, while QUADSPI and FSMC enable external NOR/PSRAM/NAND expansion.

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 core and architecture but reduced memory: 1 MB flash → 1 MB, 320 KB SRAM → 128 KB; no QUADSPI or FSMC; lacks SAI and Chrom-ART. | Suitable for simpler UI-less sensor nodes or basic motor control where external memory or audio is unnecessary. | Select when BOM cost reduction is prioritized over future feature scalability and external memory expansion capability. |
| STM32U575ZIT6 | Successor series with Arm Cortex-M33, TrustZone, higher crypto acceleration (AES-GCM), lower active current (21 µA/MHz), but no SMPS support and different pinout. | Better suited for security-critical IoT endpoints requiring PSA Level 3 certification and secure element functionality. | Choose for new designs demanding certified secure boot and hardware-enforced isolation - not for drop-in replacement due to architectural and pinout differences. |
Compared with STM32L476RG, the STM32L496RGT6 delivers expanded memory, richer analog/peripheral set, and advanced graphics/audio capabilities - justifying its use in feature-rich edge devices. Versus STM32U575ZIT6, it trades modern security extensions for proven low-power stability, broader ecosystem support, and direct SMPS integration critical for long-life battery operation.

FAQ
What is the maximum operating frequency and corresponding power consumption in Run mode?
The STM32L496RGT6 operates at up to 80 MHz with 100 DMIPS performance. In Run mode with ART Accelerator enabled and internal LDO, typical current is 91 µA/MHz; with external SMPS supplying VDD12 = 1.10 V, it drops to 37 µA/MHz - verified per Table 27 of DS11585 Rev 20.
Does this MCU support hardware cryptographic acceleration beyond HASH?
No - the STM32L496RGT6 integrates only a dedicated SHA-256 hardware accelerator (HASH module) and true random number generator (RNG). It does not include AES, DES, or PKA engines; those features appear in later series like STM32L5 or STM32U5.
Can the LQFP64 package accommodate all peripherals listed in the datasheet?
Yes - the LQFP64 variant (part number suffix 'R') maps essential peripherals including USB OTG FS, 2× CAN, 2× SAI, QUADSPI, and up to 51 GPIOs. Full peripheral availability requires careful pin multiplexing per Table 15; some functions like FSMC or second SAI are not accessible in this package.
What development tools are officially supported for firmware debugging and programming?
STMicroelectronics officially supports STM32CubeIDE with ST-LINK/V2-1 debugger, STM32CubeProgrammer for flashing, and STM32CubeMX for initialization code generation. Serial Wire Debug (SWD) via PA13/PA14 is the primary interface; JTAG is also available but requires additional pins not present on LQFP64.
