This asymmetric architecture lets the M7 handle heavy number-crunching or real-time control loops while the M4 runs communications stacks, sensor fusion, or low-power background tasks — splitting the workload without a second chip. ## 156-WLCSP — what the fine-pitch package means for the board Housed in a 156-ball WLCSP measuring 4.96 x 4.64 mm, this package saves board area at the cost of tighter routing rules. The 0.4 mm or 0.5 mm ball pitch (typical for this class) demands via-in-pad or microvia fanout on the top layer; a four-layer PCB with filled vias is the usual starting point. The 168 I/O count means nearly every ball is used, so signal breakout planning matters early. ## Connectivity and peripheral set The peripheral list includes Ethernet MAC, dual CAN interfaces, USB OTG FS/HS, multiple SPI, I²C, UART/USART, and a QSPI memory interface — enough to serve as the main processor in a connected gateway or a multi-protocol industrial controller.","metaTitle":"STM32H747ZIY6TR STM32H7 Dual-Core MCU, 240/480 MHz","metaDescription":"STMicroelectronics STM32H747ZIY6TR 32-bit dual-core ARM Cortex-M4/M7 MCU. 240 MHz / 480 MHz, 2MB Flash, 1MB RAM, 168 I/O, 156-WLCSP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"240MHz, 480MHz","Series":"STM32H7","Package":"Tape & Reel (TR)","RAM Size":"1M x 8","Core Size":"32-Bit Dual-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, I²S, LCD, POR, PWM, WDT","Connectivity":"CANbus, EBI/EMI, Ethernet, I²C, IrDA, LINbus, MDIO, MMC/SD/SDIO, QSPI, SAI, SPDIF, SPI, SWPMI, UART/USART, USB OTG","Mounting Type":"Surface Mount","Number of I/O":"168","Core Processor":"ARM® Cortex®-M4/M7","Package / Case":"156-UFBGA, WLCSP","Product Status":"Active","Data Converters":"A/D 23x16b; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32H747","Program Memory Size":"2MB (2M x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"156-WLCSP (4.96x4.64)","Voltage - Supply (Vcc/Vdd)":"1.62V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$11.2231","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9e5180384e9546619b8201d29aca5a1d.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between STM32H747ZIY6TR and STM32H747XIY6?","answer":"The difference is in the Flash and RAM density.
