That core speed, combined with the DSP instruction set, lets it handle real-time control loops and audio processing without a separate DSP chip. ## Peripheral set for system-level integration This part carries a connectivity set that reduces external IC count: CANbus for industrial or automotive networks, USB OTG for dual-role host/device, SAI for I²S audio, and SPDIF-Rx for digital audio input. Brown-out detect, POR, and a low-voltage detector are built in, so an external supervisor is optional. The internal oscillator means you can bring up UART bootloading without an external crystal, though the PLL accuracy for USB will want a 25 MHz or 8 MHz external resonator. STMicroelectronics lists the STM32F446VCT7 as Active. No last-time-buy or end-of-life notice applies to this order code as of the current product status. For new designs, the active lifecycle means no forced redesign from obsolescence in the near term.","metaTitle":"STM32F446VCT7 STM32F4 ARM Cortex-M4 MCU, 180 MHz","metaDescription":"STM32F446VCT7 32-bit ARM Cortex-M4 MCU from STMicroelectronics. 180 MHz core, 256 KB Flash, 128 KB SRAM, industrial temp -40°C to 105°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"180MHz","Series":"STM32F4","Package":"Tray","RAM Size":"128K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, I²S, LVD, POR, PWM, WDT","Connectivity":"CANbus, EBI/EMI, I²C, IrDA, LINbus, SAI, SD, SPDIF-Rx, SPI, UART/USART, USB, USB OTG","Mounting Type":"Surface Mount","Number of I/O":"81","Core Processor":"ARM® Cortex®-M4","Package / Case":"100-LQFP","Product Status":"Active","Data Converters":"A/D 16x12b; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32F446","Program Memory Size":"256KB (256K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~105°C(TA)","Supplier Device Package":"100-LQFP (14x14)","Voltage - Supply (Vcc/Vdd)":"1.7V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$12.3700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/cd1250ee9b471f9370d29b0641a72b62.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F446VCT7/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between STM32F446VCT7 and STM32F446VCT6?","answer":"The STM32F446VCT7 and STM32F446VCT6 share the same core, memory, and peripheral set. The suffix difference typically indicates a packaging or temperature grade variant — the VCT7 is the industrial-temperature (-40°C to 105°C) version in a 100-LQFP tray. The VCT6 is the commercial-temperature (0°C to 70°C) variant.
