For a typical control loop sampling an ADC at 1 MHz and running a PID filter with floating-point coefficients, the 72 MHz leaves enough margin to also handle a USB or CAN protocol stack without starving the control task. 256 KB of Flash is a practical size for a field-upgradable firmware image with a bootloader and one or two application slots. The 40K x 8 SRAM supports moderate data buffers — for example, a 1 KB USB endpoint buffer, a 2 KB CAN message queue, and a 16 KB DSP workspace still leave room for the stack and heap. ## Peripheral set and connectivity — what is on-chip The STM32F302CCT6TR integrates a DMA controller, I²S audio interface, power-on-reset (POR), PWM timers, and a watchdog timer — the usual STM32F3 complement for motor-control and audio applications. This set lets a single MCU handle a CANopen fieldbus, a USB virtual COM port for configuration, and a SPI link to an external FRAM or display — all without glue logic.","metaTitle":"ST STM32F302CCT6TR ARM Cortex-M4 MCU, 72 MHz, 256 KB Flash","metaDescription":"STMicroelectronics STM32F302CCT6TR 32-bit ARM Cortex-M4 MCU, 72 MHz core, 256 KB Flash, 40K x 8 RAM, 48-LQFP, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"72MHz","Series":"STM32F3","Package":"Tape & Reel (TR); Cut Tape (CT)","RAM Size":"40K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"DMA, I²S, POR, PWM, WDT","Connectivity":"CANbus, I²C, IrDA, LINbus, SPI, UART/USART, USB","Mounting Type":"Surface Mount","Number of I/O":"37","Core Processor":"ARM® Cortex®-M4","Package / Case":"48-LQFP","Product Status":"Active","Data Converters":"A/D 9x12b; D/A 1x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32F302","Program Memory Size":"256KB (256K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"48-LQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"2V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.4500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/abc7277dd36d539fcf2d3c46eff57822.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F302CCT6TR/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between STM32F302CCT6 and STM32F302CCT6TR?","answer":"The two share the same die, package (48-LQFP), and electrical specifications.
