STMicroelectronics STM32F413RGT6

Overview

STM32F413RGT6 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 in industrial HMI, portable medical devices, and smart sensor hubs requiring real-time signal acquisition and low-power operation.

For engineers reviewing the STM32F413RGT6 datasheet, STM32F413RGT6 pinout, STM32F413RGT6 application, or STM32F413RGT6 equivalent, key selection criteria include its 100 MHz ART-accelerated flash execution, dual 12-bit DACs with DMA support, 12-bit 2.4 MSPS ADC with 16 channels, DFSDM-based PDM microphone interface, and LQFP64 package compatibility with legacy STM32F4 designs.

Technical Context

This MCU implements the Arm Cortex-M4 core with hardware FPU and Adaptive Real-Time Accelerator (ART) enabling zero-wait-state execution from Flash at 100 MHz. Its memory subsystem includes 1.5 MB of on-chip Flash, 320 KB SRAM, and flexible external memory controller supporting NOR/PSRAM.

The peripheral set integrates two independent DFSDMs for sigma-delta modulator filtering, six digital filters per DFSDM, stereo PDM microphone input with sound source localization, and a dedicated low-power timer (LPTIM1) for sub-millisecond timing in Stop mode - all coordinated via 16-stream DMA and nested vectored interrupt controller (NVIC).

FAQ

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

The STM32F413RGT6 achieves 100 MHz CPU frequency using the Arm Cortex-M4 core with Adaptive Real-Time Accelerator (ART) enabled. ART eliminates Flash wait states by caching instructions and data, allowing deterministic zero-wait-state execution directly from 1.5 MB on-chip Flash memory under standard 1.7–3.6 V supply conditions.

Does this MCU support PDM microphone interfaces and what is required to use them?

Yes - the STM32F413RGT6 integrates two DFSDM peripherals, each supporting up to six digital filters for sigma-delta modulators. It natively accepts PDM microphone inputs on dedicated pins (e.g., PC1–PC3, PD10–PD12) and provides dynamic delay tuning for sound source localization. No external decimation filters or clock generators are needed.

What are the low-power modes and their typical current consumption?

It supports Run, Sleep, Stop (with Flash in Stop or Deep Power Down), and Standby modes. Typical current draw is 112 µA/MHz in Run mode (peripheral off), 42 µA in Stop mode (fast wakeup), 15 µA in Stop mode (deep power down), and 1.1 µA in Standby without RTC. VBAT supply draws 1 µA for RTC backup at 25 °C.

Is USB OTG FS fully integrated and does it require external components?

Yes - the USB OTG FS peripheral includes a full-speed transceiver with integrated PHY. Only a single 1.5 kΩ pull-up resistor on D+ is required for device mode; no external PHY, level shifters, or termination resistors are needed, simplifying PCB layout and reducing BOM cost.
