The 37 I/O lines and connectivity set (CAN, I²C, SPI, UART, LIN) give it enough interface headroom for a sensor hub or fieldbus node without a port expander. The base product number STM32F334 spans several Flash and package options, so if a future design needs more memory or a different footprint, the migration stays within the same family. ## 48-LQFP — hand-solderable, rework-friendly The exposed pad isn't present on this package variant, so thermal dissipation relies on the leadframe — keep the ambient airflow or add a small heatsink if the core runs sustained loads near 72 MHz with all peripherals active.","metaTitle":"STM32F334C6T6TR ARM Cortex-M4 MCU, 72 MHz, 32 KB Flash","metaDescription":"STMicroelectronics STM32F334C6T6TR 32-bit ARM Cortex-M4 MCU at 72 MHz with 32 KB Flash, 12 KB SRAM, 37 I/O, CAN, industrial temp range.","metaKeywords":null},"attributes":{"series":"STM32F3","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":"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":"37","Core Processor":"ARM® Cortex®-M4","Package / Case":"48-LQFP","Product Status":"Active","Data Converters":"A/D 15x12b; 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":"48-LQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"2V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.7400","priceTiers":[{"qty":1,"price":"$6.74000","currency":"USD"},{"qty":10,"price":"$6.08900","currency":"USD"},{"qty":25,"price":"$5.80600","currency":"USD"},{"qty":100,"price":"$5.04150","currency":"USD"},{"qty":250,"price":"$4.81488","currency":"USD"},{"qty":500,"price":"$4.39004","currency":"USD"},{"qty":1000,"price":"$3.86220","currency":"USD"},{"qty":2400,"price":"$3.86220","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/8a888bd6c4c82b6773e27135551f6f4a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F334C6T6TR/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between STM32F334C6T6TR and STM32F334C6T6?","answer":"The two parts are electrically and functionally identical.
