Program memory is 64 KB of Flash, with 12 KB SRAM for data and stack. The 12 KB SRAM (organized as 12K x 8) is tight for heavy buffering, but sufficient for single-axis field-oriented control or a single-phase PFC algorithm. The 37 I/O lines in the 48-LQFP package leave room for sensor interfaces, gate-drive signals, and a display or keypad. On-chip analog peripherals include a 15-channel 12-bit ADC and a 3-channel 12-bit DAC, reducing the need for external converters in mixed-signal control loops. ROHS3 compliance is confirmed, covering EU and global regulatory requirements.","metaTitle":"STM32F334C8T7 STMicroelectronics ARM Cortex-M4 MCU, 72 MHz","metaDescription":"STMicroelectronics STM32F334C8T7 32-bit ARM Cortex-M4 MCU with FPU, 64 KB Flash, 12 KB SRAM, 72 MHz, 15-ch 12-bit ADC, 3-ch 12-bit DAC, -40°C to 105°C.","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":"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":"$6.8400","priceTiers":[{"qty":1,"price":"$6.84000","currency":"USD"},{"qty":10,"price":"$6.18300","currency":"USD"},{"qty":25,"price":"$5.89560","currency":"USD"},{"qty":80,"price":"$5.11925","currency":"USD"},{"qty":250,"price":"$4.88916","currency":"USD"},{"qty":500,"price":"$4.45776","currency":"USD"},{"qty":1000,"price":"$3.88257","currency":"USD"},{"qty":2500,"price":"$3.73877","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/8a888bd6c4c82b6773e27135551f6f4a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F334C8T7/alternatives.json"},"ai":{"faq":[{"question":"Is STM32F334C8T7 compatible with STM32F334C8T6?","answer":"Yes, the STM32F334C8T7 is pin-compatible and functionally identical to the STM32F334C8T6.
