For a BOM freeze or a multi-year production run, this part does not introduce obsolescence risk at the component level. The base product number is STM32F446, which covers multiple density and package variants. If a future design requires more Flash or a different footprint, the family shares the same core and peripheral set, so migration stays within the same toolchain and software investment.","metaTitle":"ST STM32F446MCY6TR ARM Cortex-M4 MCU, 180 MHz, 256 KB Flash","metaDescription":"STMicroelectronics STM32F446MCY6TR 32-bit MCU: ARM Cortex-M4 at 180 MHz, 256 KB Flash, 128 KB RAM, 63 I/O, CAN, USB OTG, 1.7-3.6 V, -40 to 85 °C, 81-UFBGA WLCSP.

ST continues to manufacture the part."},{"question":"What is the closest pin-compatible alternative to STM32F446MCY6TR?","answer":"Within the STM32F446 family, the STM32F446RET6 uses the same core and peripherals but comes in an LQFP-64 package instead of the WLCSP. The pinout differs due to the package change, so a board redesign is required. For a drop-in WLCSP replacement, check the STM32F446MCT6 or STM32F446MEY6 variants — they share the same 81-ball footprint with different Flash densities."},{"question":"Where can I buy STM32F446MCY6TR in tape and reel?","answer":"The STM32F446MCY6TR is available in Tape & Reel packaging and is sourced to order against an RFQ. Contact our sales desk for a quote and current lead time."},{"question":"What is STM32F446MCY6TR's listed speed?","answer":"The core runs at 180 MHz, which is the maximum clock for the STM32F446 series. That clock rate supports single-cycle DSP instructions and hardware floating-point operations."},{"question":"Does STM32F446MCY6TR have the same pinout as STM32F446RET6?","answer":"No. The STM32F446MCY6TR uses an 81-ball WLCSP package, while the STM32F446RET6 comes in an LQFP-64. The ball/pin assignments and count differ, so a direct PCB replacement is not possible without a layout change."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32F446MCY6TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32F446MCY6TR when reusing this data.
