Product details
Overview
STM32L496VGT6P 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 - deployed in battery-powered medical sensors, portable HMI terminals, and industrial data loggers requiring extended runtime and secure firmware updates.
For engineers reviewing the STM32L496VGT6P datasheet, STM32L496VGT6P pinout, STM32L496VGT6P application, or STM32L496VGT6P equivalent, key selection criteria include verified low-power mode current (25 nA shutdown, 426 nA standby with RTC), dual-bank flash for safe OTA updates, 136 I/Os with 5 V tolerance, and hardware crypto acceleration for secure boot and firmware signing.
Technical Context
The STM32L496VGT6P integrates an Adaptive Real-time Accelerator (ART) 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 dynamic voltage scaling and multiple low-power modes with sub-µA retention - including Stop 2 (2.57 µA) and Standby with RTC (426 nA).
It features three independent PLLs (system, USB, audio), dual-clock domain operation (HSE/LSE + internal RC oscillators), and hardware-peripheral isolation via firewall and memory protection unit (MPU). The device implements true random number generation (RNG), CRC calculation unit, and 96-bit unique ID for secure identity management.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating?
The STM32L496VGT6P operates at up to 80 MHz with an Adaptive Real-time Accelerator (ART) enabling zero-wait-state execution from flash. Its performance is rated at 100 DMIPS (Dhrystone 2.1), achieving 1.25 DMIPS/MHz. This is confirmed in Section 2.2 of DS11585 Rev 20 and validated by CoreMark® scores of 273.55 at 80 MHz (3.42 CoreMark/MHz).
Does this MCU support hardware cryptographic acceleration, and which algorithms are implemented?
Yes, the STM32L496VGT6P includes a dedicated HASH hardware accelerator supporting SHA-256 only. It does not implement AES or RSA in hardware. SHA-256 acceleration is used for secure boot signature verification, firmware image hashing, and TLS handshake integrity - documented in Section 3.27 and Table 2 of the datasheet.
What are the supported low-power modes and their typical current consumption values?
Validated low-power modes include: Shutdown (25 nA), Standby (108 nA), Standby with RTC (426 nA), Stop 2 (2.57 µA), and Stop 2 with RTC (2.86 µA). All values measured at 3.3 V, 25 °C, with ART enabled and flash execution - per Tables 4 and 26–34 in DS11585 Rev 20. VBAT mode draws 320 nA for RTC + backup registers.
Is external SMPS control supported, and how is it implemented?
Yes, the STM32L496VGT6P supports external SMPS control via the VDD12 pin and associated control logic (Section 3.10.3). It directly drives an external DC-DC converter to supply the 1.2 V core domain, reducing active-mode current to 37 µA/MHz (vs. 91 µA/MHz with internal LDO), as verified in Table 27 and Figure 42 of the datasheet.
