The 180 MHz core speed puts this part in the performance tier of the STM32F4 family. With a single-cycle multiply and hardware FPU, it handles FFTs, PID loops, and sensor fusion without a separate DSP. The flash wait states need attention at this clock — the datasheet recommends 5 wait states above 150 MHz, so budget for that in your timing closure if you're running tight loops from Flash. 256 KB of program Flash and 128 KB of SRAM give enough room for a real-time OS, a TCP/IP stack, and moderate application code. The 128 KB RAM handles double-buffered audio or two CAN message queues without overflow. If your firmware needs more than this, the STM32F446RE variant doubles the Flash to 512 KB while staying pin-compatible. The part includes CANbus, USB OTG (FS), SPDIF-Rx, SAI (serial audio interface), and up to 6 SPI/I²C ports. The 50 GPIOs are enough for a TFT display, keypad, and external memory via the EBI/EMI interface. Brown-out reset, POR, and a programmable voltage detector are on-chip, reducing external supervisor IC count.","metaTitle":"STM32F446RCT7 STM32F4 MCU, 180MHz, 256KB Flash, 64-LQFP","metaDescription":"STMicroelectronics STM32F446RCT7 ARM Cortex-M4 MCU, 180MHz core, 256KB Flash, 128KB RAM, -40°C to 105°C, 64-LQFP.","metaKeywords":null},"attributes":{"series":"STM32F4","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","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":"50","Core Processor":"ARM® Cortex®-M4","Package / Case":"64-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":"64-LQFP (10x10)","Voltage - Supply (Vcc/Vdd)":"1.7V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$9.7300","priceTiers":[{"qty":1,"price":"$9.73000","currency":"USD"},{"qty":10,"price":"$8.78900","currency":"USD"},{"qty":25,"price":"$8.38040","currency":"USD"},{"qty":80,"price":"$7.27675","currency":"USD"},{"qty":230,"price":"$6.94974","currency":"USD"},{"qty":440,"price":"$6.33652","currency":"USD"},{"qty":960,"price":"$5.51891","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/cd1250ee9b471f9370d29b0641a72b62.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F446RCT7/alternatives.json"},"ai":{"faq":[{"question":"What is the maximum frequency of STM32F446RCT7?","answer":"The core runs at 180 MHz."},{"question":"Is STM32F446RCT7 compatible with STM32F446RCT6?","answer":"Yes, the STM32F446RCT6 is a drop-in compatible variant with the same flash, RAM, and package — verify the temperature grade matches your requirement."},{"question":"What are the key differences between STM32F446RCT7 and STM32F446RE?","answer":"The STM32F446RE doubles the Flash to 512 KB while staying pin-compatible in the same 64-LQFP package.
