With the single-cycle multiply and hardware FPU of the Cortex-M4, it can handle FFTs and filter loops without an external DSP. The 128 KB SRAM provides enough working memory for double-buffered data streams or a modest RTOS heap. ## Memory and peripheral integration 256 KB of Flash is sized for mid-complexity firmware — enough for a USB stack, a CANopen node, or a motor-control algorithm with room for field-upgrade staging. The 24-channel 12-bit ADC covers multi-sensor acquisition without an external mux; the two 12-bit DAC channels can generate analog setpoints or audio waveforms. Connectivity includes CANbus for industrial networks, USB OTG for host/device flexibility, and SAI for I²S audio codec interfaces. The package is surface-mount only. The small ball pitch means the PCB layout should follow ST's recommended footprint and fanout via pattern. It is ROHS3 compliant.","metaTitle":"STM32F446ZCH6 STM32F4 MCU, 180 MHz, 256KB Flash, 144-UFBGA","metaDescription":"STMicroelectronics STM32F446ZCH6 ARM Cortex-M4 MCU, 180 MHz, 256KB Flash, 128KB SRAM, 114 I/O, 24-ch 12-bit ADC, -40 to 85°C.","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":"114","Core Processor":"ARM® Cortex®-M4","Package / Case":"144-UFBGA","Product Status":"Active","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)","Voltage - Supply (Vcc/Vdd)":"1.7V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$9.7700","priceTiers":[{"qty":1,"price":"$9.77000","currency":"USD"},{"qty":10,"price":"$8.82800","currency":"USD"},{"qty":25,"price":"$8.41760","currency":"USD"},{"qty":80,"price":"$7.30900","currency":"USD"},{"qty":416,"price":"$6.98046","currency":"USD"},{"qty":832,"price":"$6.36454","currency":"USD"},{"qty":1248,"price":"$5.54331","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/cd1250ee9b471f9370d29b0641a72b62.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F446ZCH6/alternatives.json"},"ai":{"faq":[{"question":"Does STM32F446ZCH6 have a built-in ADC?","answer":"Yes, it integrates a 24-channel 12-bit ADC and a 2-channel 12-bit DAC on-chip."},{"question":"What is the closest functional second-source for STM32F446ZCH6?","answer":"The STM32L151CBU6A is a lower-power ARM Cortex-M3 alternative from the STM32L1 series, but it runs at 32 MHz with 37 I/O and lacks the 180 MHz performance, 114 I/O, and USB OTG of the STM32F446ZCH6.
