Product details

The STM32F427ZGT6 is a 32-bit ARM Cortex-M4 MCU from the STM32F4 series, clocked at 180 MHz with 1 MB of Flash program memory and 256 KB of RAM. This part is built for industrial control, motor drives, building automation, and IoT gateway applications where a single chip must handle real-time control loops, Ethernet connectivity, and local HMI interaction without an external communications processor.

Connectivity and peripheral set — one chip for the system bus

The Ethernet MAC with dedicated DMA and the dual CAN interfaces let this MCU serve as the central node on a factory-floor network, bridging a Modbus TCP segment to a CANopen drive chain.

Frequently asked questions

What is STM32F427ZGT6's listed speed?

The core runs at 180 MHz, which is the maximum clock for the STM32F4 series Cortex-M4. At this speed, single-cycle multiply-accumulate and hardware FPU handle real-time FFT or PID loops without external DSP.

What is the closest pin-compatible alternative to STM32F427ZGT6?

The STM32F429ZGT6 is pin-compatible and adds a TFT LCD controller; the STM32F407ZGT6 shares the same footprint but has 192 KB RAM and no Ethernet. All share the 144-LQFP layout, so a board respin for a different density is minimal.

What compliance documentation does ST provide for STM32F427ZGT6?

STMicroelectronics provides RoHS and REACH compliance declarations for the STM32F4 series. The 144-LQFP package is lead-free and halogen-free per the standard ST environmental compliance datasheet.
