The trade-off: WLCSP requires tighter PCB land patterns, controlled solder-paste volume, and X-ray inspection after reflow. It is not hand-solderable — plan for an automated SMT line. The 83 I/O count is available in this package, so peripheral-rich designs do not lose GPIO density despite the tiny body. Brown-out detect, DMA, and a watchdog timer are on-chip, reducing external supervisor IC count.","metaTitle":"STM32L443CCF6TR ARM Cortex-M4 MCU, 80MHz, 256KB Flash, WLCSP","metaDescription":"STMicroelectronics STM32L443CCF6TR 32-bit MCU with ARM Cortex-M4 core at 80MHz, 256KB Flash, 64KB SRAM, 49-WLCSP package, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"80MHz","Series":"STM32L4","Package":"Tape & Reel (TR)","RAM Size":"64K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, LCD, PWM, WDT","Connectivity":"CANbus, I²C, IrDA, LINbus, MMC/SD, QSPI, SAI, SPI, SWPMI, UART/USART, USB","Mounting Type":"Surface Mount","Number of I/O":"83","Core Processor":"ARM® Cortex®-M4","Package / Case":"49-UFBGA, WLCSP","Product Status":"Active","Data Converters":"A/D 16x12b; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32L443","Program Memory Size":"256KB (256K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"49-WLCSP (3.14x3.13)","Voltage - Supply (Vcc/Vdd)":"1.71V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.2040","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a2b759f28e4523297545b32a262e3197.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32L443CCF6TR/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between STM32L443CCF6TR and STM32L443CCT6?","answer":"The primary difference is the package: the STM32L443CCF6TR uses a 49-ball WLCSP (3.14 x 3.13 mm), while the STM32L443CCT6 uses an LQFP-48 package with gull-wing leads.
