STMicroelectronics STM32F413CGU6

Overview

STM32F413CGU6 from STMicroelectronics is a 32-bit Arm® Cortex®-M4 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 in industrial HMI, portable medical devices, and smart sensor hubs requiring real-time signal acquisition and low-power operation.

For engineers reviewing the STM32F413CGU6 datasheet, STM32F413CGU6 pinout, STM32F413CGU6 application, or STM32F413CGU6 equivalent, key selection criteria include its 100 MHz Cortex-M4+FPU performance, 1.5 MB on-chip Flash with ART Accelerator™, dual 12-bit DACs, 12-bit 2.4 MSPS ADC, and support for PDM microphone arrays via 6-channel DFSDM - all in a compact UFQFPN48 package.

Technical Context

The STM32F413CGU6 integrates an Adaptive Real-time Accelerator (ART Accelerator™) enabling zero-wait-state execution from Flash at 100 MHz, and features eBAM (enhanced Batch Acquisition Mode) for deterministic analog data capture across multiple channels. Its dual-mode Quad-SPI interface supports memory-mapped XIP and direct transfers to DMA, while the DFSDM subsystem includes dynamic PDM delay tuning for stereo sound source localization.

It implements a multi-AHB bus matrix with dedicated buses for CPU, DMA, and peripherals, ensuring concurrent access without contention. The embedded 320 KB SRAM is partitioned into 192 KB general-purpose SRAM and 128 KB CCM (Core-Coupled Memory), accessible only by CPU for critical real-time code and data - isolating latency-sensitive operations from DMA traffic.

Key Specifications

FAQ

What is the maximum operating temperature range for STM32F413CGU6?

The STM32F413CGU6 is qualified for industrial operation from −40 °C to +85 °C ambient temperature. This rating is specified in the official datasheet (DS11581 Rev 7, Section 6.3.1) and validated across all electrical parameters including Flash endurance, ADC linearity, and USB OTG functionality.

Does STM32F413CGU6 support external SDRAM via FSMC?

No. The STM32F413CGU6 includes a Flexible Static Memory Controller (FSMC), but it supports only SRAM, PSRAM, and NOR Flash - not SDRAM. SDRAM support requires the STM32F42xxx or STM32F43xxx series, which feature an SDRAM controller instead of FSMC.

Can the DFSDM module interface directly with PDM microphones?

Yes. The DFSDM module accepts raw PDM bitstreams directly on dedicated GPIO pins (e.g., PA1–PA7). Each of its six filters includes a programmable clock generator, digital notch filter, and decimation stage - enabling standalone PDM-to-PCM conversion without external FPGA or ASIC.

Is the ART Accelerator™ enabled by default after reset?

Yes. The ART Accelerator™ is active by default upon power-on reset, as confirmed in the Reference Manual (RM0383, Section 3.3.2). It remains enabled unless explicitly disabled via the ART_CTRL register - ensuring zero-wait-state Flash execution from startup without software initialization.
