The 72 MHz core, combined with the DMA and PWM peripherals, keeps the CPU free for higher-level tasks while the hardware handles time-critical I/O. ## Memory sizing: 32 KB Flash, 12 KB SRAM — what fits 32 KB of Flash and 12 KB of SRAM target compact firmware: a single motor-control FOC algorithm, a CANopen stack with a few PDOs, or a sensor-hub aggregator. The 12 KB SRAM is enough for a modest RTOS heap and a couple of ping-pong buffers for the ADC or DAC. If your application needs a full TCP/IP stack or a large data logger, you will outgrow this part — step up to the STM32F334K8 (64 KB Flash) or the STM32F334R8 (64 KB Flash, 48-pin). The 105°C ceiling means it can sit next to a power stage or in a sealed outdoor enclosure without needing a separate high-temp variant. If your design lives in a climate-controlled lab, the commercial-grade STM32F334K6T6 (0°C to 70°C) is a cost-down option — but for production BOMs that see a factory floor or a vehicle, the T7 grade is the safer call. ## Analog front-end: 9-channel 12-bit ADC and three 12-bit DACs Nine 12-bit ADC channels and three 12-bit DACs are integrated on-chip, reducing external analog components. The ADC can sample multiple current-sense resistors and a voltage feedback simultaneously; the DACs can generate reference voltages or analog setpoints for external comparators. For a three-phase motor drive, you get one ADC channel per phase plus a DC-link voltage sense, with DACs for current-limit thresholds or offset nulling — all without external op-amps or DACs. ## Connectivity: CAN, LIN, I²C, SPI, UART — what each bus is for CAN and LIN interfaces make this MCU a natural fit for automotive body-control modules, sensor nodes, or industrial fieldbus gateways. The I²C and SPI ports handle local peripherals — external EEPROM, temperature sensors, display controllers. UART/USART plus IrDA support legacy serial links and infrared communication. With 25 I/O pins in a 32-LQFP package, you have enough headroom for a few external interrupts and a parallel LCD data bus if needed. ## Package and footprint: 32-LQFP (7x7 mm) The 25 I/O pins are distributed around the four sides, leaving room for a ground plane under the package.","metaTitle":"STM32F334K6T7 STMicroelectronics MCU, ARM Cortex-M4 72 MHz","metaDescription":"STM32F334K6T7 32-bit ARM Cortex-M4 MCU, 72 MHz, 32 KB Flash, 12 KB SRAM, 9x12b ADC, 3x12b DAC, CAN, -40°C to 105°C, 32-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":"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 ~ 105°C (TA)","Supplier Device Package":"32-LQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"2V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.2800","priceTiers":[{"qty":1,"price":"$6.28000","currency":"USD"},{"qty":10,"price":"$5.67800","currency":"USD"},{"qty":25,"price":"$5.41360","currency":"USD"},{"qty":80,"price":"$4.70050","currency":"USD"},{"qty":230,"price":"$4.48926","currency":"USD"},{"qty":440,"price":"$4.09316","currency":"USD"},{"qty":1500,"price":"$3.56501","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/6d9a764cc3544541b3a556dbb8f66feb.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F334K6T7/alternatives.json"},"ai":{"faq":[{"question":"Is STM32F334K6T7 pin compatible with STM32F334K6T6?","answer":"Yes, the STM32F334K6T7 and STM32F334K6T6 share the same base product number STM32F334 and the same 32-LQFP package.
