STMicroelectronics STM32F413ZHT6

Overview

STM32F413ZHT6 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 operates from 1.7–3.6 V across –40 °C to 105 °C and targets embedded control with real-time signal acquisition in industrial HMI and portable medical devices.

For engineers reviewing the STM32F413ZHT6 datasheet, STM32F413ZHT6 pinout, STM32F413ZHT6 application, or STM32F413ZHT6 equivalent, key selection factors include its 144-pin LQFP package, dual 12-bit DACs, 12-bit 2.4 MSPS ADC, 6-channel DFSDM for PDM microphone arrays, and ART Accelerator™ enabling zero-wait-state execution from Flash at 100 MHz.

Technical Context

The STM32F413ZHT6 integrates an Arm Cortex-M4 core with floating-point unit and DSP extensions, coupled with ST's Adaptive Real-time Accelerator (ART Accelerator™) that eliminates Flash wait states via instruction prefetch and branch cache. Its memory subsystem includes 1.5 MB of on-chip Flash, 320 KB SRAM, and support for external parallel memories via FSMC.

It features a comprehensive peripheral set optimized for mixed-signal edge applications: one 12-bit 2.4 MSPS ADC with up to 16 channels, two synchronized 12-bit DACs, six digital sigma-delta filters (DFSDM), stereo PDM microphone interfaces, and hardware-accelerated sound source localization logic - all operating under dynamic efficiency management across multiple low-power modes.

FAQ

What is the maximum operating temperature range for STM32F413ZHT6?

The STM32F413ZHT6 is qualified for industrial operation from –40 °C to +105 °C ambient temperature. This rating is confirmed in Section 6.3.1 of DS11581 Rev 7 and applies to all LQFP144 variants. The device supports extended temperature screening options up to +125 °C in select part numbers (e.g., STM32F413ZHT6V), but the standard ZHT6 grade is rated to +105 °C.

Does STM32F413ZHT6 support external SDRAM via FSMC?

No - the Flexible Static Memory Controller (FSMC) in STM32F413ZHT6 supports only SRAM, PSRAM, NOR Flash, and LCD interfaces with 8-/16-bit data buses. It does not implement the address/data multiplexing or refresh logic required for SDRAM. For SDRAM support, ST recommends STM32F42xxx or STM32F7xxx families with FMC peripheral.

Can the two DAC outputs be synchronized for differential signal generation?

Yes - DAC1 and DAC2 can be triggered simultaneously using software, timer, or external event synchronization. Both DACs share common calibration registers and support aligned 12-bit mode, enabling true differential output generation (e.g., for driving balanced audio lines or precision current sources) with matched settling time and gain error.

Is USB OTG FS functionality available without external PHY components?

Yes - the STM32F413ZHT6 integrates a full-speed USB 2.0 OTG PHY with internal transceivers on PA11 (D−) and PA12 (D+). Only external 1.5 kΩ pull-up resistor on D+ (for device mode) and basic ESD protection diodes are required; no external PHY chip is needed for standard USB device, host, or OTG operation.
