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.","metaTitle":"ST STM32F446ZEH7TR ARM Cortex-M4 MCU, 180 MHz, 512 KB Flash","metaDescription":"STMicroelectronics STM32F446ZEH7TR 32-bit MCU with 180 MHz Cortex-M4, 512 KB Flash, 132 KB RAM, 114 I/O, -40°C to 105°C, 144-UFBGA.
