It carries 50 I/O lines, a 16-channel 12-bit ADC, a 2-channel 12-bit DAC, and connectivity spanning CANbus, USB OTG, SAI, and SPDIF-Rx. The -40°C to 105°C operating range and 1.7 V to 3.6 V supply make it a candidate for motor drives, outdoor telecom, and industrial sensor hubs where extended temperature and mixed-signal integration are required. ## 180 MHz — what it buys you on the bus The Cortex-M4 core runs at 180 MHz. The 256 KB Flash and 128 KB RAM support real-time control loops and DMA transfers. ## Lifecycle: EOL hot — plan the last-time buy now STMicroelectronics lists the STM32F446RCT7TR as EOL hot. The last-time-buy window is open. ## Peripheral set and package — board-level fit The 64-LQFP (10x10 mm) package with 50 I/O fits two-layer boards where trace routing is tight. The CANbus and USB OTG interfaces allow direct connection to industrial fieldbus and a host PC for firmware updates or data logging. SAI and SPDIF-Rx support digital audio input — useful for audio-over-IP gateways or smart speakers.","metaTitle":"STM32F446RCT7TR 32-bit ARM Cortex-M4 MCU, 180 MHz, 256 KB Flash","metaDescription":"STMicroelectronics STM32F446RCT7TR: 32-bit ARM Cortex-M4 single-core at 180 MHz, 256 KB Flash, 128 KB RAM, 50 I/O, CAN/USB OTG/SAI, -40°C to 105°C, 64-LQFP.
