Product details

180 MHz Cortex-M4 with 512 KB Flash — what it means for the BOM

The STMicroelectronics STM32F446ZEH7TR is a 32-bit ARM Cortex-M4 MCU from the STM32F4 series, clocked at 180 MHz with 512 KB Flash and 132 KB RAM. It carries 114 I/O lines, a full communications suite including USB OTG, CANbus, I²C, SPI, and UART, plus 24-channel 12-bit ADC and dual 12-bit DAC. Rated for -40°C to 105°C and 1.7 V to 3.6 V supply, it targets industrial control, motor drives, and outdoor telecom equipment where the extended temperature range and peripheral density matter.

Industrial temperature and BGA footprint — design constraints

The 144-UFBGA (10x10 mm) package saves board area but demands careful PCB layout. The -40°C to 105°C operating range covers most factory-floor and outdoor enclosures.

Active production — no LTB concern

This part carries an Active product status per the manufacturer. No last-time-buy or end-of-life notice is in effect, so it remains suitable for new designs and production BOMs. Sourced and quoted to order through independent distribution; availability and current pricing confirmed at quote time.

Frequently asked questions

What is STM32F446ZEH7TR's core speed?

The core runs at 180 MHz, which is the maximum clock for the ARM Cortex-M4 in this STM32F4 series variant.

What is the closest pin-compatible alternative to STM32F446ZEH7TR?

Within the STM32F446 family, the STM32F446ZET6 (LQFP-144) offers the same core and memory but in a QFP package — not pin-compatible due to different footprint. For a true BGA alternative, consider the STM32F446ZEH6 (same UFBGA-144, -40 to 85°C grade) if you can accept the narrower temperature range.
