The ARM Cortex-M4 core with single-precision FPU runs at 72 MHz, giving this MCU the arithmetic throughput for real-time control loops — digital power supplies, motor field-oriented control, or sensor fusion. The FPU handles a multiply-accumulate in a single cycle, so you are not burning cycles in software emulation. Paired with the 12 KB SRAM and 32 KB Flash, the part fits applications where the firmware stays under 32 KB and the data buffer fits within 12 KB; anything larger moves you to the STM32F334K8T6 with 64 KB Flash. ## Analog front-end: 9 ADC channels, 3 DAC outputs Nine 12-bit ADC channels and three 12-bit DAC channels are integrated on-chip, enough to sample multiple analog signals (current, voltage, temperature) and output control references without external converters. The ADC samples at up to 5 Msps in interleaved mode, which matters for time-critical current sensing in motor drives. The DACs can generate analog setpoints or waveforms directly. ## Connectivity and peripherals for industrial control The PWM timer with complementary outputs and dead-time insertion is built for half-bridge and three-phase inverter control. DMA offloads data transfers from the core, keeping the CPU free for control math. Housed in a 32-LQFP (7x7 mm) with 25 I/O lines, this is a compact surface-mount package suited for space-constrained PCBs in industrial enclosures.","metaTitle":"STM32F334K6T6 ARM Cortex-M4 MCU, 72 MHz, 32 KB Flash","metaDescription":"STMicroelectronics STM32F334K6T6 32-bit MCU with ARM Cortex-M4 core at 72 MHz, 32 KB Flash, 12 KB RAM, 9x12-bit ADC, 3x12-bit DAC, CAN, I²C, SPI, UART.","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":"12K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"DMA, POR, PWM, WDT","Connectivity":"CANbus, I²C, IrDA, LINbus, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"25","Core Processor":"ARM® Cortex®-M4","Package / Case":"32-LQFP","Product Status":"Active","Data Converters":"A/D 9x12b; D/A 3x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32F334","Program Memory Size":"32KB (32K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"32-LQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"2V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.5400","priceTiers":[{"qty":1,"price":"$6.54000","currency":"USD"},{"qty":10,"price":"$5.87400","currency":"USD"},{"qty":25,"price":"$5.55280","currency":"USD"},{"qty":80,"price":"$4.81250","currency":"USD"},{"qty":250,"price":"$4.56568","currency":"USD"},{"qty":500,"price":"$4.09678","currency":"USD"},{"qty":1000,"price":"$3.45511","currency":"USD"},{"qty":2500,"price":"$3.28235","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/8a888bd6c4c82b6773e27135551f6f4a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F334K6T6/alternatives.json"},"ai":{"faq":[{"question":"Can STM32F334K6T6 replace STM32F334K8T6?","answer":"The STM32F334K6T6 and STM32F334K8T6 are pin-compatible in the same 32-LQFP package, but the K6 variant has 32 KB Flash versus 64 KB on the K8.
