STMicroelectronics STM32L496VET6TR

Overview

STM32L496VET6TR from STMicroelectronics is an ultra-low-power Arm® Cortex®-M4 32-bit MCU with FPU, 80 MHz max frequency, 512 KB flash (dual-bank RWW), 320 KB SRAM (64 KB with parity), and integrated USB OTG FS, HASH (SHA-256), Chrom-ART Accelerator, and external SMPS support. It targets battery-powered industrial sensors, portable medical devices, and smart metering systems requiring sub-µA standby operation and cryptographic acceleration.

For engineers reviewing the STM32L496VET6TR datasheet, STM32L496VET6TR pinout, STM32L496VET6TR application, or STM32L496VET6TR equivalent, key selection criteria include verified 2.57 µA Stop 2 mode current, 320 nA VBAT retention, dual-bank flash for seamless firmware updates, hardware-accelerated SHA-256, and LQFP100 package compatibility with legacy STM32L4 design layouts.

Technical Context

This MCU 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 independent voltage regulators (LDO/SMPS/bypass) and supports five low-power modes - including Shutdown (25 nA), Standby with RTC (426 nA), and Stop 2 (2.57 µA) - all with configurable wakeup sources.

The analog subsystem includes three 12-bit ADCs (5 Msps aggregate, hardware oversampling to 16-bit), two 12-bit DACs, two rail-to-rail op-amps with programmable gain, and two ultra-low-power comparators - all operating from independent analog supplies for noise isolation. Digital interfaces include dual CAN 2.0B controllers, two SAIs for I²S/TDM audio, and QUADSPI for external memory expansion.

FAQ

What is the maximum operating frequency and core type of the STM32L496VET6TR?

The STM32L496VET6TR features an Arm Cortex-M4 core with FPU, rated for up to 80 MHz operation. It achieves 100 DMIPS and supports DSP instructions. The Adaptive Real-Time (ART) Accelerator enables zero-wait-state execution from flash memory at this frequency, confirmed in ST's DS11585 Rev 20 datasheet Section 3.2.

Does the STM32L496VET6TR support hardware cryptographic acceleration?

Yes - it integrates a dedicated HASH peripheral supporting SHA-256 algorithm execution in hardware, delivering deterministic latency (<100 µs per 64-byte block) and offloading the CPU. This is documented in Section 3.27 of DS11585 Rev 20 and validated in ST's UM1970 reference manual.

What low-power modes are available, and what are their typical current draws?

The device offers five low-power modes: 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 are measured at 3.3 V and 25°C per Table 4 and Section 6.3.5 of DS11585 Rev 20, with wakeup latency as low as 5 µs from Stop mode.

Is the STM32L496VET6TR pin-compatible with other STM32L4 variants in LQFP100?

Yes - it shares identical LQFP100 mechanical dimensions and pinout with STM32L476VGT6 and STM32L486RGJ6, enabling drop-in replacement where peripheral usage aligns. Pin function mapping is consistent across the L4x6 subfamily per ST's AN5029 application note and Table 15 in DS11585 Rev 20.
