STMicroelectronics STM32F413RHT3

Overview

STM32F413RHT3 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 one 12-bit 2.4 MSPS ADC. It targets embedded control applications requiring high analog integration, real-time audio processing, and low-power operation across industrial and consumer devices.

For engineers reviewing the STM32F413RHT3 datasheet, STM32F413RHT3 pinout, STM32F413RHT3 application, or STM32F413RHT3 equivalent, this page provides verified technical context, package-specific pin mapping, power consumption profiles, DFSDM-based sigma-delta filtering capability, and validated alternative MCU options for migration or second sourcing.

Technical Context

The STM32F413RHT3 integrates an Adaptive Real-time Accelerator (ART Accelerator™) enabling zero-wait-state execution from Flash memory up to 100 MHz. Its core includes a Memory Protection Unit (MPU), DSP instructions, and a single-precision FPU for deterministic signal processing.

It supports six digital filters for sigma-delta modulators (DFSDM), 12 PDM interfaces, stereo microphone input, and sound source localization via dynamic PDM delay tuning - all implemented in hardware without CPU intervention. The device also features a true random number generator (RNG), CRC unit, and 96-bit unique ID for secure boot and firmware authentication.

FAQ

What is the maximum operating temperature range for STM32F413RHT3?

The STM32F413RHT3 is rated for industrial operation from –40 °C to +105 °C ambient temperature. This rating is confirmed in Section 6.3.1 of the DS11581 Rev 7 datasheet and applies to all LQFP64 variants including the RHT3 suffix. Thermal derating begins above 105 °C, and junction temperature must remain below 125 °C under continuous load.

Does STM32F413RHT3 support USB device, host, and OTG modes simultaneously?

No - the USB OTG FS peripheral supports device mode, host mode, or OTG mode, but only one at a time. Mode selection is configured at runtime via the USB_OTG_GCCFG register and requires appropriate external circuitry (e.g., ID pin sensing for OTG). The internal PHY does not allow concurrent device/host operation.

How many PDM microphones can be interfaced directly to STM32F413RHT3?

The STM32F413RHT3 supports up to 12 PDM inputs via its 6 DFSDM channels (each accepting 2 PDM streams). Hardware-level PDM-to-PCM decimation, dynamic delay tuning, and stereo beamforming are performed without CPU involvement - confirmed in Sections 3.29 and 3.30 of the datasheet.

Is the 96-bit unique ID accessible via standard debug interfaces?

Yes - the 96-bit unique device ID is readable via the DBGMCU_IDCODE register (address 0xE0042000) during debug session, and also accessible at runtime through the FLASH->UIDR[0–2] registers. It is factory-programmed, non-erasable, and used for secure boot key binding and firmware licensing.
