Product details
Overview
STM32F423ZHT3 from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU, 100 MHz max clock, 1.5 MB flash, 320 KB SRAM, and integrated USB OTG FS, dual DACs, and AES hardware encryption. It targets embedded control in resource-constrained industrial HMI, portable medical devices, and low-power sensor hubs requiring real-time signal processing and secure firmware updates.
For engineers reviewing the STM32F423ZHT3 datasheet, STM32F423ZHT3 pinout, STM32F423ZHT3 application, or STM32F423ZHT3 equivalent, key selection criteria include its 100 MHz Cortex-M4+FPU performance, 1.5 MB flash for complex firmware, dual 12-bit DACs for analog output generation, DFSDM support for PDM microphone arrays, and -40 °C to 105 °C extended temperature operation.
Technical Context
The STM32F423ZHT3 integrates an Adaptive Real-time Accelerator (ART Accelerator™) enabling zero-wait-state execution from flash at 100 MHz, and features Dynamic Efficiency Line architecture with eBAM for optimized power/performance trade-offs across operating modes. Its memory subsystem includes flexible external static memory controller (FSMC) supporting NOR/PSRAM and Dual-mode Quad-SPI for high-speed serial flash.
It implements three CAN 2.0B controllers, one SAI interface for audio streaming, and six digital filters for sigma-delta modulators (DFSDM) with stereo PDM microphone input and sound source localization capability - all coordinated via a 16-stream DMA controller and nested vectored interrupt controller (NVIC) with 240 interrupts.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F413ZHT6 | Same LQFP144 package, but 1 MB flash, 256 KB SRAM, no DFSDM, no USB OTG FS PHY (requires external transceiver) | Lacks integrated USB PHY and PDM audio support - unsuitable for USB device-class or voice-enabled designs | Select when USB host/device functionality is unnecessary and BOM cost reduction is critical. |
| STM32L4R5ZIT6 | Cortex-M4 @ 120 MHz, 2 MB flash, 640 KB SRAM, but no USB OTG FS, no DFSDM, lower temp grade (-40 °C to 85 °C) | Optimized for ultra-low-power sleep modes (200 nA standby), lacks industrial temp and USB PHY - better for long-life battery IoT, not real-time USB/audio | Prefer for energy-constrained applications where USB and audio are absent, and extended temperature is not required. |
Compared with STM32F423ZHT3, the STM32F413ZHT6 trades flash size and integrated USB PHY for lower cost, while the STM32L4R5ZIT6 prioritizes sub-µA standby over real-time USB/audio capability - making the ZHT3 uniquely suited for industrial USB-connected sensor hubs with audio feedback.

FAQ
What is the maximum operating temperature for the STM32F423ZHT3?
The STM32F423ZHT3 is rated for operation from -40 °C to +105 °C ambient temperature, validated per ST's industrial qualification standards. This extended range supports deployment in enclosures near motors, power supplies, or outdoor environments where thermal margins exceed standard commercial-grade MCUs.
Does the STM32F423ZHT3 include an integrated USB physical layer?
Yes, the STM32F423ZHT3 integrates a full-speed USB 2.0 OTG transceiver with internal PHY, supporting device, host, and OTG roles without external components. Pins PA11 (D-) and PA12 (D+) are dedicated USB lines with built-in termination and pull-up resistors controllable via software.
How many independent ADC channels does the STM32F423ZHT3 support?
The STM32F423ZHT3 includes one 12-bit ADC (ADC1) with up to 16 external input channels and 2.4 MSPS sampling rate. Channel selection is configurable via software, and conversions can be triggered by timers, EXTI lines, or software commands - enabling synchronized multi-sensor acquisition.
Is the STM32F423ZHT3 pin-compatible with other STM32F423 variants?
No - the STM32F423ZHT3 uses the LQFP144 package (20 × 20 mm), while other 'Z' variants like STM32F423CHT6 use LQFP64 and STM32F423VHT6 use LQFP100. Pinouts differ significantly across packages; migration requires PCB redesign and signal reassignment per the respective pin definition tables in DS11580 Rev 8.
