The SPDIF-Rx interface is less common on mid-range MCUs — it directly decodes digital audio from an optical or coaxial input without an external decoder chip. The internal oscillator trims out the external crystal for cost-sensitive builds, but the clock tree still supports an external source when timing accuracy matters. ## Package and mounting — 144-LQFP with 20x20 mm body The 144-LQFP (20x20 mm) is a hand-solderable, inspectable package — no BGA rework station needed.","metaTitle":"STM32F446ZCT6 ARM Cortex-M4 MCU, 180MHz, 256KB Flash","metaDescription":"STMicroelectronics STM32F446ZCT6 32-bit MCU with ARM Cortex-M4 FPU at 180MHz, 256KB Flash, 128KB RAM, 114 I/O, 24x12-bit ADC, 144-LQFP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Speed":"180MHz","title":"STM32F446ZCT6","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":"114","Core Processor":"ARM® Cortex®-M4","Package / Case":"144-LQFP","Data Converters":"A/D 24x12b; 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":"144-LQFP (20x20)","Voltage - Supply (Vcc/Vdd)":"1.7V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$12.9800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/cd1250ee9b471f9370d29b0641a72b62.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F446ZCT6/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to STM32F446ZCT6?","answer":"Within the STM32F4 family, the STM32F446ZET6 offers the same pinout and peripherals but with 512 KB Flash instead of 256 KB.
