That means a 32-bit FIR filter or a PID loop with floating-point coefficients runs without a software emulation tax. The 128 KB of RAM gives enough headroom for a real-time operating system heap, a few moderate-sized frame buffers, or a protocol stack — but if your application needs a large display buffer or extensive data logging, you will want to audit the RAM budget early. The 256 KB Flash is sized for mid-complexity firmware; the STM32F4 series has larger-density siblings if the code image outgrows it. ## Connectivity and peripherals — what is on the bus This MCU includes CANbus (2.0B active), USB OTG (full-speed and high-speed with on-chip PHY), SPDIF-Rx for digital audio input, SAI for I²S audio, and an external memory interface (EBI/EMI) that can gluelessly attach SRAM, NOR Flash, or an LCD controller. The 12-bit ADC has 16 channels, and there are two 12-bit DACs. For a design that needs to talk to a CAN network, log data to an external parallel SRAM, and stream audio over I²S, the STM32F446VCT6 covers all of that without an external bridge chip. ## Package and layout — 100-LQFP with exposed pad A via-stitched thermal land under the pad, connected to a ground plane, is the standard practice.","metaTitle":"STM32F446VCT6 STM32F4 ARM Cortex-M4 MCU, 180 MHz","metaDescription":"STMicroelectronics STM32F446VCT6 32-bit ARM Cortex-M4 MCU, 180 MHz, 256 KB Flash, 128 KB RAM, CAN/USB OTG/SPI/I²C, -40 to 85°C, 100-LQFP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Speed":"180MHz","title":"STM32F446VCT6","Series":"STM32F4","Package":"Tray","RAM Size":"128K x 8","Core Size":"32-Bit Single-Core","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","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~85°C(TA)","Supplier Device Package":"100-LQFP (14x14)","Voltage - Supply (Vcc/Vdd)":"1.7V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$11.5600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/cd1250ee9b471f9370d29b0641a72b62.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F446VCT6/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to STM32F446VCT6?","answer":"Within the STM32F446 series, the STM32F446RET6 and STM32F446VET6 are pin-compatible options with larger Flash (512 KB) while keeping the same 100-LQFP footprint, 180 MHz core, and peripheral set.

Flash and RAM differ (256 KB/128 KB on the F446 vs 1 MB/192 KB on the F407). Pin compatibility is not guaranteed without checking the specific pinout tables — the peripheral mix and some alternate-function mappings changed between the two series."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32F446VCT6","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32F446VCT6 when reusing this data.
