The 168 GPIOs and rich peripheral set — Ethernet MAC, CAN 2.0, USB OTG HS, multiple SPI/I²C/UART, plus a 24-channel 12-bit ADC and a 2-channel 12-bit DAC — mean this chip can sit at the center of a complex embedded system without needing external bridges or memory expansion for most designs. ## Industrial temperature range and BGA package — field-fit considerations The 216-ball TFBGA (13×13 mm) is a fine-pitch BGA — not a field-swap part. On-site replacement means hot air or a rework station, and the board needs X-ray inspection afterward. ## Supply range and power-up sequence At 1.7 V the 216 MHz PLL may not lock cleanly — the datasheet's operating conditions table is the authority for minimum VDD at full speed. The part includes brown-out detect and POR, so external reset supervision is optional for most designs. Internal oscillator is present, but for Ethernet or USB operation an external 25 MHz crystal is the usual choice for clock accuracy. For BOM planning, the base product number STM32F746 covers multiple Flash and package variants within the same family, so a pin-compatible drop-in with different memory density is possible if the application requirements shift.","metaTitle":"STM32F746NGH6TR STM32F7 ARM Cortex-M7 MCU, 216MHz","metaDescription":"STMicroelectronics STM32F746NGH6TR: 32-bit ARM Cortex-M7 at 216MHz, 1MB Flash, 320KB SRAM, 168 I/O, Ethernet/CAN/USB OTG, -40 to 85°C, 216-TFBGA.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Speed":"216MHz","title":"STM32F746NGH6TR","Series":"STM32F7","Package":"Tape & Reel (TR)","RAM Size":"320K x 8","Core Size":"32-Bit Single-Core","Peripherals":"Brown-out Detect/Reset, DMA, I²S, LCD, POR, PWM, WDT","Connectivity":"CANbus, EBI/EMI, Ethernet, I²C, IrDA, LINbus, SAI, SD, SPDIF-Rx, SPI, UART/USART, USB OTG","Mounting Type":"Surface Mount","Number of I/O":"168","Core Processor":"ARM® Cortex®-M7","Package / Case":"216-TFBGA","Data Converters":"A/D 24x12b; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32F746","Program Memory Size":"1MB (1M x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"216-TFBGA (13x13)","Voltage - Supply (Vcc/Vdd)":"1.7V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$13.3295","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/df8acc91a62dcb77b186f2aeee64486d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F746NGH6TR/alternatives.json"},"ai":{"faq":[{"question":"What is the exact difference between STM32F746NGH6TR and STM32F746NGH6?","answer":"The only difference is the shipping medium: STM32F746NGH6TR is the tape-and-reel variant for automated assembly lines, while STM32F746NGH6 ships in trays. The silicon, package, pinout, and all electrical specifications are identical between the two order codes."},{"question":"Is the STM32F746NGH6TR obsolete or still active?","answer":"It is still active — ST lists it as current production with no discontinuation notice."},{"question":"Can I use STM32F746NGH6TR as a direct replacement for STM32F745?","answer":"The STM32F746 is a higher-performance member of the same family with the same pinout in the 216-TFBGA package, so it is a drop-in replacement at the footprint level. The F746 adds a hardware JPEG codec and a few extra peripheral features, but the core Cortex-M7, memory map, and BGA ball-out are compatible. Firmware will need recompilation if you are using the extra peripherals, but basic GPIO and serial functions should migrate without board changes."},{"question":"Does STM32F746NGH6TR have any known compatibility issues with STM32F7 evaluation boards?","answer":"No known compatibility issues. The STM32F746G-DISCO and NUCLEO-F746ZG evaluation boards use the same STM32F746 MCU in a different package (LQFP176 or BGA216 on the discovery), so code developed on those boards runs directly on this part. The peripheral set and memory map are identical across the F746 line."},{"question":"What is STM32F746NGH6TR's listed speed?","answer":"The core runs at 216 MHz maximum, which is the top speed for the STM32F7 series. At that clock rate the part delivers over 1000 CoreMark points with the ART Accelerator enabled."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32F746NGH6TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32F746NGH6TR when reusing this data.
