The peripheral set includes CANbus, USB OTG, SAI, SPDIF-Rx, and an EBI/EMI memory controller — enough to bridge to external SRAM, FRAM, or a parallel LCD without a CPLD. That means no last-time-buy clock is running, and the part remains eligible for new-design-in. The base product number STM32F446 covers a density-and-package family; if the 144-UFBGA footprint is not mandatory, the LQFP-144 variant (STM32F446ZET6) shares the same core and peripheral set for a simpler rework process.","metaTitle":"STM32F446ZCH7 ARM Cortex-M4 MCU, 180 MHz, 256 KB Flash","metaDescription":"STMicroelectronics STM32F446ZCH7 32-bit MCU, 180 MHz ARM Cortex-M4, 256 KB Flash, 128 KB RAM, 114 I/O, -40 to 105°C, 144-UFBGA (7x7 mm).","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Speed":"180MHz","title":"STM32F446ZCH7","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-UFBGA","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 ~ 105°C (TA)","Supplier Device Package":"144-UFBGA (7x7)","Voltage - Supply (Vcc/Vdd)":"1.7V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.7118","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/cd1250ee9b471f9370d29b0641a72b62.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F446ZCH7/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between the STM32F446ZCH7 and the STM32F446ZET6?","answer":"The STM32F446ZCH7 is in a 144-UFBGA (7x7 mm) package, while the STM32F446ZET6 is in an LQFP-144.
