STMicroelectronics STM32F413VGT3

Overview

STM32F413VGT3 from STMicroelectronics is an Arm® Cortex®-M4 32-bit microcontroller with FPU, 100 MHz max CPU frequency, 1.5 MB Flash, 320 KB SRAM, and integrated USB OTG FS, dual DACs, and DFSDM for audio/sensor processing. It targets embedded control systems requiring real-time signal acquisition, low-power operation, and rich peripheral integration - such as industrial HMI, portable medical devices, and smart sensor hubs.

For engineers reviewing the STM32F413VGT3 datasheet, STM32F413VGT3 pinout, STM32F413VGT3 application, or STM32F413VGT3 equivalent, key selection criteria include its 100 MHz ART-accelerated execution from Flash, -40°C to 105°C extended temperature grade, LQFP100 package with 82 GPIOs, and dual-mode Quad-SPI interface for external memory expansion.

Technical Context

The STM32F413VGT3 implements an Adaptive Real-time Accelerator (ART Accelerator™) enabling zero-wait-state execution from Flash at 100 MHz, paired with a Memory Protection Unit (MPU) for secure task isolation in RTOS environments. Its enhanced Batch Acquisition Mode (eBAM) optimizes ADC/DAC/DFSDM data throughput for synchronized multi-channel sensing.

It integrates two independent 12-bit DACs with configurable output buffers, one 12-bit 2.4 MSPS ADC with up to 16 channels, and six digital filters for sigma-delta modulators (DFSDM), supporting stereo PDM microphone input and sound source localization - all operating under dynamic voltage scaling (1.7–3.6 V).

FAQ

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

The STM32F413VGT3 achieves 100 MHz CPU frequency using its Adaptive Real-time Accelerator (ART Accelerator™), which pre-fetches and caches instructions from Flash memory to eliminate wait states. This is validated across the full 1.7–3.6 V supply range and –40°C to +105°C temperature range, with no external clock multiplier required.

Does the STM32F413VGT3 support true hardware random number generation?

Yes - it integrates a certified True Random Number Generator (RNG) compliant with NIST SP800-90B and AIS-31 standards. The RNG uses analog entropy sources and includes built-in health tests, delivering cryptographically secure 32-bit words via dedicated register reads without software post-processing.

How many PDM microphone channels can be processed simultaneously?

The STM32F413VGT3 supports up to six concurrent PDM microphone inputs via its DFSDM peripheral, with dedicated data input pins (e.g., PD12–PD15, PE7–PE8). Each DFSDM channel performs real-time decimation and filtering, enabling stereo or multi-mic array processing without CPU intervention.

What are the mandatory external components for stable operation?

Mandatory components include two 2.2 µF X7R ceramic capacitors on VCAP_1 and VCAP_2 pins, 100 nF + 4.7 µF decoupling per VDD/VSS pair, a 4–26 MHz crystal for HSE (if used), and a 32.768 kHz crystal for RTC. NRST requires a 10 kΩ pull-up; BOOT0 needs a 10 kΩ pull-down for normal Flash boot.
