This peripheral set suits sensor acquisition, closed-loop analog output, and waveform generation without external ADC/DAC ICs. The on-chip DMA, POR, and PWM timers offload the core for deterministic timing. The 37 I/O lines in the 48-LQFP package provide ample GPIO for local control and status indication. For dual-sourcing resilience, the base product number STM32F334 covers density and package variants across the series — a pin-compatible sibling with larger Flash (e.g., STM32F334R8T7) is a drop-in replacement if firmware size grows. Supplied in a 48-LQFP package (7x7 mm body), surface-mount. The 48-LQFP footprint is common across the STM32F334 value-line density options, easing board layout reuse.","metaTitle":"ST STM32F334C8T7TR ARM Cortex-M4 MCU, 72 MHz, 64 KB Flash","metaDescription":"STMicroelectronics STM32F334C8T7TR 32-bit ARM Cortex-M4 MCU, 72 MHz core, 64 KB Flash, 12K x 8 SRAM, 15x12b ADC, 3x12b DAC, -40 to 105°C, 48-LQFP.","metaKeywords":null},"attributes":{"series":null,"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)","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":"64KB (64K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 105°C (TA)","Supplier Device Package":"48-LQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"2V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.9238","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/8a888bd6c4c82b6773e27135551f6f4a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F334C8T7TR/alternatives.json"},"ai":{"faq":[{"question":"What are the alternatives to STM32F334C8T7TR?","answer":"Within the STM32F334 series, a pin-compatible alternative with larger Flash is the STM32F334R8T7 (64 KB Flash, same 48-LQFP package).
