The 10-channel 12-bit ADC and three 12-bit DACs give enough analog front-end for current sensing and reference outputs in a single-chip control loop. ## Peripheral set and connectivity for industrial buses On-chip peripherals include DMA, POR, PWM, and WDT — the PWM timers are the key enabler for generating complementary dead-time-controlled gate drive signals. With 25 I/O pins in a 32-pin package, every pin earns its keep. The supply range of 2V to 3.6V lets it run from a 3.3V rail or a pair of alkaline cells, though the 72 MHz clock will pull more current at the higher voltage. ## Package and rework: 32-UFQFPN with exposed pad Orientation is marked by a pin 1 chamfer on the top side, visible under magnification.","metaTitle":"STM32F334K8U6 ARM Cortex-M4 MCU, 72 MHz, 64 KB Flash","metaDescription":"STMicroelectronics STM32F334K8U6 32-bit ARM Cortex-M4 MCU, 72 MHz, 64 KB Flash, 16 KB RAM, 10x12b ADC, 3x12b DAC, CAN, I2C, SPI, -40°C to 85°C, 32-UFQFPN.","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":"16K 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-UFQFN Exposed Pad","Product Status":"Active","Data Converters":"A/D 10x12b; D/A 3x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32F334","Program Memory Size":"64KB (64K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"32-UFQFPN (5x5)","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":230,"price":"$4.56570","currency":"USD"},{"qty":440,"price":"$4.09677","currency":"USD"},{"qty":945,"price":"$3.45511","currency":"USD"},{"qty":2940,"price":"$3.28235","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/f93488a1cb613d6452cafbf37be6a148.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F334K8U6/alternatives.json"},"ai":{"faq":[{"question":"Is STM32F334K8U6 obsolete or still active?","answer":"The STM32F334K8U6 is listed as Active by STMicroelectronics with ROHS3 compliance."},{"question":"What is the difference between STM32F334K8U6 and STM32F334K8T6?","answer":"The difference is the package: the K8U6 is in a 32-UFQFPN (5x5 mm) with exposed pad, while the K8T6 is in a 32-LQFP (7x7 mm).
