The part is intended for digital power control, motor drives, and industrial automation where the combination of a floating-point unit, high-resolution timers, and rich analog peripherals (21-channel 12-bit ADC, three 12-bit DACs) is needed. ## Memory and peripheral budget for BOM sizing The 51 GPIOs in the 64-pin LQFP package leave room for parallel sensor interfaces, keypad matrices, or external memory-mapped peripherals without a port expander. The CAN 2.0B interface supports J1939 or CANopen stacks for vehicle or factory-floor networking, while the three UART/USART modules handle RS-232, RS-485, or LIN bus links.","metaTitle":"STM32F334R8T7TR STM32F3 MCU, ARM Cortex-M4, 72 MHz","metaDescription":"STM32F334R8T7TR 32-bit MCU with ARM Cortex-M4 core at 72 MHz, 64 KB Flash, 12 KB RAM, 21x12b ADC, 3x12b DAC, CAN/I²C/SPI/UART.

The difference is the shipping medium: the T7TR suffix denotes Tape & Reel packaging, while the T6 suffix typically indicates a tray or tube format. Electrically and functionally they are identical. For high-volume assembly lines that feed from reels, the T7TR variant is the correct BOM line."},{"question":"Can STM32F334R8T7TR be replaced by STM32F334R8T6?","answer":"Yes, the two are functionally identical — same core, memory map, peripherals, and package. The only difference is the shipping medium. If your assembly line accepts tray or tube parts, the T6 variant is a drop-in substitute. For reel-fed lines, stick with the T7TR."},{"question":"Is STM32F334R8T7TR RoHS compliant?","answer":"The evidence does not explicitly list a RoHS compliance status. However, as a current-production STMicroelectronics part in a 64-LQFP package, it is standard industry practice for such devices to be RoHS-compliant and lead-free. Confirm with the manufacturer's latest datasheet or the product change notification (PCN) database for the specific date code."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32F334R8T7TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32F334R8T7TR when reusing this data.
