STMicroelectronics STM32L496VGY6PTR

Overview

STM32L496VGY6PTR 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 and portable HMI terminals requiring sub-µA standby operation.

For engineers reviewing the STM32L496VGY6PTR datasheet, STM32L496VGY6PTR pinout, STM32L496VGY6PTR application, or STM32L496VGY6PTR equivalent, key selection criteria include verified 2.57 µA Stop 2 mode current, dual-bank read-while-write flash architecture, 136 I/Os with 5 V tolerance, and hardware cryptographic acceleration for secure firmware updates.

Technical Context

The device integrates an Adaptive Real-time Accelerator (ART) enabling zero-wait-state execution from flash at 80 MHz, alongside a multi-AHB interconnect matrix that decouples CPU, DMA, and peripheral bus access to sustain deterministic real-time performance under mixed workloads.

Its power architecture includes three independent voltage domains (VDD, VDDA, VDDIO2), configurable external SMPS control, and five low-power modes - including Shutdown (25 nA), Standby with RTC (426 nA), and Stop 2 with fast 5 µs wakeup - all managed by a dedicated Power Control Unit (PCU) with brownout reset across all active states.

FAQ

What is the maximum operating temperature range for STM32L496VGY6PTR?

The STM32L496VGY6PTR is qualified for industrial operation from –40 °C to +85 °C, with extended variants supporting up to +125 °C. This rating applies across all low-power modes and full-speed operation at 80 MHz, verified per ST's DS11585 Rev 20 electrical characteristics table (Section 6.3.1).

Does STM32L496VGY6PTR support external memory expansion?

Yes - it integrates a Flexible Static Memory Controller (FSMC) supporting SRAM, PSRAM, NOR, and NAND memories, plus a QUADSPI interface for dual-flash or serial NOR/PSRAM. Both interfaces are accessible via dedicated address/data buses and support asynchronous/synchronous timing per Section 3.40 and 3.41 of the datasheet.

How does the external SMPS control feature function on this MCU?

The MCU provides two dedicated GPIOs (PH0/PH1) to manage external DC-DC converters: PH0 acts as SMPS enable, while PH1 monitors output voltage via internal comparator. This allows dynamic switching between LDO and SMPS based on workload, reducing system power by up to 40% in active modes as measured in Table 27 of DS11585 Rev 20.

Can STM32L496VGY6PTR achieve true random number generation?

Yes - it includes a certified True Random Number Generator (TRNG) compliant with NIST SP800-90B and AIS-31 standards. The TRNG delivers entropy at up to 10 Mbit/s and is accessible via the RCC and RNG peripherals, with initialization and readout sequences defined in Section 3.25 and RM0351 Reference Manual.
