If your rail dips during a cold-crank or battery sag, the BOR holds the core in reset until the supply recovers cleanly. ## Package and thermal pad — layout notes for the 48-UFQFN Housed in a 48-UFQFN with exposed pad (7x7 mm body), the part is surface-mount only. Without that via stitch, junction temperature climbs faster than the 85°C ambient spec allows at high core load. For a design starting today, this part carries no imminent obsolescence risk. The base product number STM32G441 covers a range of Flash and package options, so a density or footprint migration stays within the same family if needed later.","metaTitle":"STM32G441CBU6 ARM Cortex-M4 MCU, 170 MHz, 128 KB Flash","metaDescription":"STM32G441CBU6 32-bit MCU with 170 MHz Cortex-M4, 128 KB Flash, 32 KB SRAM, 18x12-bit ADC, 4x12-bit DAC, -40 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":"170MHz","Series":"STM32G4","Package":"Tray","RAM Size":"32K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, I²S, POR, PWM, WDT","Connectivity":"CANbus, I²C, IrDA, LINbus, SAI, SPI, UART/USART, USB","Mounting Type":"Surface Mount","Number of I/O":"42","Core Processor":"ARM® Cortex®-M4","Package / Case":"48-UFQFN Exposed Pad","Product Status":"Active","Data Converters":"A/D 18x12b; D/A 4x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32G441","Program Memory Size":"128KB (128K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"48-UFQFPN (7x7)","Voltage - Supply (Vcc/Vdd)":"1.71V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.5223","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/617f970f95dd7e57a69315817089e6bf.pdf","sourceUrl":null},"ai":{"faq":[{"question":"How does STM32G441CBU6 compare to STM32G431CBU6?","answer":"Both are 170 MHz Cortex-M4 parts in the same 48-UFQFN package. The STM32G441CBU6 carries 128 KB Flash and 32 KB SRAM, while the STM32G431CBU6 offers 128 KB Flash and 32 KB SRAM as well — the difference is in the analog peripheral set: the G441 includes a 12-bit DAC with four channels versus the G431's two DAC channels. If your application needs four analog output channels, the G441 is the fit; otherwise the two are pin-compatible and interchangeable on the same board."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32G441CBU6","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32G441CBU6 when reusing this data.
