Product details

The STM32F439ZGT7 is a 32-bit ARM Cortex-M4 single-core MCU from STMicroelectronics' STM32F4 series, clocked at 180 MHz with 1 MB Flash and 256 KB SRAM. That clock rate puts it in the performance tier for real-time control loops, Ethernet packet handling, and DSP-style math without an external co-processor.

Connectivity and peripherals — Ethernet, USB OTG, CANbus

On-chip Ethernet MAC, USB OTG, and CANbus make this part a natural fit for an industrial controller or a gateway node that bridges a fieldbus to a local display or cloud uplink. The EBI/EMI interface can drive an external SRAM or NOR Flash for data logging. Peripherals include DMA, PWM timers, and an LCD controller — enough to drive a small TFT panel directly without a separate graphics accelerator. The 24-channel 12-bit ADC and dual 12-bit DAC cover analog sensing and closed-loop control on the same die.

Frequently asked questions

What is STM32F439ZGT7's listed speed?

The core runs at 180 MHz, which is the maximum clock for this ARM Cortex-M4 device. That speed supports real-time control loops and DSP operations without an external accelerator.

What is the closest pin-compatible alternative to STM32F439ZGT7?

Within the STM32F4 family, the STM32F429 series shares the same 144-LQFP footprint and peripheral set. Verify Flash and SRAM sizes match your firmware requirements before substituting.
