The 12-bit ADC resolution (15 channels) and 12-bit DAC (3 channels) are a strong match for digital power conversion and motor-control feedback loops. ## 49-WLCSP package — rework and layout notes The 49-WLCSP package measures 2.89 x 3.74 mm.","metaTitle":"STM32F334C8Y7TR ARM Cortex-M4 MCU, 72 MHz, 64 KB Flash","metaDescription":"STMicroelectronics STM32F334C8Y7TR 32-bit MCU with ARM Cortex-M4 core at 72 MHz, 64 KB Flash, 12 KB RAM, 15-ch 12-bit ADC, 3-ch 12-bit DAC, -40 to 105°C","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":"49-UFBGA, WLCSP","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":"49-WLCSP (2.89x3.74)","Voltage - Supply (Vcc/Vdd)":"2V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.2713","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/8a888bd6c4c82b6773e27135551f6f4a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F334C8Y7TR/alternatives.json"},"ai":{"faq":[{"question":"Is STM32F334C8Y7TR equivalent to STM32F334C8Y6?","answer":"The STM32F334C8Y6 is a close sibling in the same STM32F334 family, sharing the same core, Flash and RAM sizes, and peripheral set. The difference is typically in the package variant or temperature range — the Y7TR uses the 49-WLCSP package in Tape & Reel. Check the specific package code and temperature grade on the Y6 variant to confirm pin-to-pin compatibility for your board."},{"question":"Does STM32F334C8Y7TR have a built-in bootloader?","answer":"Yes. Like all STM32 devices, it includes a factory-programmed bootloader in system memory that supports USART, I²C, SPI, and CAN interfaces for programming over the serial wire. The bootloader is activated by pulling the BOOT0 pin high on reset."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32F334C8Y7TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32F334C8Y7TR when reusing this data.
