Product details

180 MHz Cortex-M4 with FPU — DSP and control-loop headroom

The STM32F446ZEH7 is a 32-bit ARM Cortex-M4 single-core MCU from ST's STM32F4 series, clocked at 180 MHz. That core includes a single-precision FPU and a full DSP instruction set, so it handles FFTs, motor-current loops, or audio filtering without an external coprocessor. The 512 KB Flash and 132 KB RAM give enough room for a real-time OS plus a moderate application stack — think a multi-axis servo drive or a digital power supply controller. Connectivity includes CANbus, USB OTG, SPI, I²C, SAI, and SPDIF-Rx. The 114 I/O lines are in a 144-UFBGA (10x10 mm) package.

Lifecycle: end-of-life — plan the last-time-buy now

The STM32F446ZEH7 is marked end-of-life (EOL hot). Production is winding down; the window for last-time-buy orders is closing.

Frequently asked questions

Is STM32F446ZEH7 obsolete?

Yes, the STM32F446ZEH7 is end-of-life (EOL hot). Production is ending; plan a last-time-buy or evaluate the pin-compatible STM32F446ZEJ6 for continued availability.

What is the operating temperature range of STM32F446ZEH7?

The STM32F446ZEH7 is rated for -40°C to 105°C, making it suitable for industrial and automotive under-hood environments.

What is the pinout of STM32F446ZEH7?

The STM32F446ZEH7 uses a 144-ball UFBGA (10x10 mm) package with 114 I/O. Pin assignments follow the STM32F446ZE family mapping; refer to the STM32F446 reference manual for the full ball-map.

Where can I buy STM32F446ZEH7?

The STM32F446ZEH7 is sourced to order through independent distribution. Submit an RFQ for current pricing and availability; we confirm lots at quote time.
