The Cortex-M4's single-cycle MAC and FPU handle field-oriented control (FOC) loops without an external DSP or dedicated motor-control coprocessor. ## Peripherals and connectivity for system integration The 52 general-purpose I/O pins in the 64-LQFP package leave room for parallel sensor interfaces and local control signals.","metaTitle":"STM32F303RBT7 STM32F3 ARM Cortex-M4 MCU, 72 MHz","metaDescription":"STM32F303RBT7 32-bit MCU with ARM Cortex-M4 core, 72 MHz speed, 128 KB Flash, 32K x 8 RAM, 22x12-bit ADC, 2x12-bit DAC, -40°C to 105°C, 64-LQFP.","metaKeywords":null},"attributes":{"series":"STM32F3","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"72MHz","Series":"STM32F3","Package":"Tray","RAM Size":"32K 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":"52","Core Processor":"ARM® Cortex®-M4","Package / Case":"64-LQFP","Product Status":"Active","Data Converters":"A/D 22x12b; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32F303","Program Memory Size":"128KB (128K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 105°C (TA)","Supplier Device Package":"64-LQFP (10x10)","Voltage - Supply (Vcc/Vdd)":"2V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.6600","priceTiers":[{"qty":1,"price":"$7.66000","currency":"USD"},{"qty":10,"price":"$6.92300","currency":"USD"},{"qty":25,"price":"$6.60080","currency":"USD"},{"qty":160,"price":"$5.73138","currency":"USD"},{"qty":320,"price":"$5.47378","currency":"USD"},{"qty":480,"price":"$4.99081","currency":"USD"},{"qty":960,"price":"$4.34683","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/a474e904fc1228ff23e70edcbd9a36eb.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F303RBT7/alternatives.json"},"ai":{"faq":[{"question":"Can I use STM32F303RBT7 for motor control applications?","answer":"Yes. The Cortex-M4 FPU and DSP instructions, combined with 22 analog input channels and dual DAC outputs, make this part well-suited for field-oriented control of brushless DC and permanent-magnet synchronous motors. The 72 MHz core provides enough headroom for the control loop plus communication stack."},{"question":"How does STM32F303RBT7 compare to the STM32L151CBU6A?","answer":"The STM32L151CBU6A uses an older Cortex-M3 core clocked at 32 MHz, has 37 I/O, and is rated to 85°C. The STM32F303RBT7 offers a faster Cortex-M4 with FPU at 72 MHz, 52 I/O, and a 105°C temperature grade — a significant step up in processing capability and environmental margin for motor-control and industrial applications."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32F303RBT7","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32F303RBT7 when reusing this data.
