If you are supporting a production line that already qualifies this BGA footprint, the immediate task is to secure enough devices for the remaining build horizon. ## 216-ball BGA — layout and assembly notes The 216-TFBGA package (13x13 mm) is a fine-pitch BGA — not a hand-solderable part. The board requires a multilayer stack-up with microvias or blind vias to route the 116 I/O and the supply rails. Operating temperature covers -40 to 85 °C, so the assembly must survive industrial reflow profiles. MSL is not stated in this record, but BGA packages typically ship at MSL 3; if the moisture-barrier bag has been open past the floor-life window, a bake before reflow is mandatory to avoid popcorning.","metaTitle":"STM32H7B3NIH6Q ARM Cortex-M7 MCU, 280 MHz, 2 MB Flash","metaDescription":"STMicroelectronics STM32H7B3NIH6Q 32-bit ARM Cortex-M7 MCU, 280 MHz, 2 MB Flash, 1.4 MB RAM, 216-TFBGA.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"280MHz","Series":"STM32H7","Package":"Tray","RAM Size":"1.4M x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, I²S, LCD, POR, PWM, WDT","Connectivity":"Camera, CANbus, EBI/EMI, HDMI-CEC, I²C, IrDA, LINbus, MDIO, MMC/SD/SDIO, PSSI, SAI, SPDIF, SPI, SWPMI, UART/USART, USB OTG","Mounting Type":"Surface Mount","Number of I/O":"116","Core Processor":"ARM® Cortex®-M7","Package / Case":"216-TFBGA","Product Status":"Obsolete","Data Converters":"A/D 20x16b; D/A 3x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32H7B3","Program Memory Size":"2MB (2M x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"216-TFBGA (13x13)","Voltage - Supply (Vcc/Vdd)":"1.62V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$55.9900","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6f23d22101b36693f41291ef10c9ab41.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32H7B3NIH6Q","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32H7B3NIH6Q when reusing this data.
