STMicroelectronics STM32F413VHT6

Overview

STM32F413VHT6 from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU, delivering 125 DMIPS at 100 MHz, featuring 1.5 MB Flash, 320 KB SRAM, USB OTG FS, dual 12-bit DACs, and two DFSDM modules for sigma-delta audio processing. It targets high-precision sensor hubs, industrial HMI displays, and USB-connected embedded audio devices.

For engineers reviewing the STM32F413VHT6 datasheet, STM32F413VHT6 pinout, STM32F413VHT6 application, or STM32F413VHT6 equivalent, key selection criteria include its 100 MHz CPU with ART Accelerator™ enabling zero-wait-state Flash execution, -40 °C to 105 °C extended temperature grade, LQFP100 package with 109 fast I/Os, and integrated DFSDM for PDM microphone arrays.

Technical Context

The STM32F413VHT6 integrates an Adaptive Real-time Accelerator (ART Accelerator™) that eliminates Flash wait states across the full 1.7–3.6 V supply range and supports dynamic voltage scaling. Its dual DFSDM modules provide 12 PDM channel inputs with hardware-accelerated filtering and stereo sound source localization timing control.

It implements a multi-AHB bus matrix supporting concurrent access to Flash, SRAM, and peripherals, and features a flexible static memory controller (FSMC) with 16-bit data bus support for NOR/PSRAM/SRAM, alongside Quad-SPI for external memory expansion - all coordinated under a single Cortex-M4 core with MPU and DSP instruction set.

FAQ

What is the maximum operating frequency and how is it sustained?

The STM32F413VHT6 operates at up to 100 MHz using its internal PLL. This frequency is sustainably achieved across the full 1.7–3.6 V supply range thanks to the ART Accelerator™, which eliminates Flash wait states and ensures deterministic execution timing even during intensive code fetches from internal memory.

Does this MCU support external memory interfaces beyond SPI flash?

Yes - the STM32F413VHT6 includes a Flexible Static Memory Controller (FSMC) supporting 16-bit parallel interfaces to external NOR Flash, PSRAM, and SRAM. It also features a Quad-SPI interface capable of executing code directly from external memory, enabling scalable memory architectures without external bus logic.

How does the DFSDM enhance audio system design?

The dual Digital Filters for Sigma-Delta Modulators (DFSDM) support up to 12 PDM microphone inputs with hardware-accelerated decimation, configurable oversampling ratios, and dynamic PDM delay tuning for sound source localization. This eliminates the need for external DSP or FPGA preprocessing in voice-controlled or acoustic monitoring systems.

Is the LQFP100 package RoHS-compliant and lead-free?

Yes - the STM32F413VHT6 in LQFP100 packaging meets RoHS Directive 2011/65/EU and is fully lead-free. It carries ST's ECOPACK®2 certification, confirming compliance with environmental standards including halogen-free materials and strict substance restrictions.
