This asymmetric architecture lets you offload real-time control loops or communications stacks to the M4 while the M7 handles number-crunching or graphics — without a second MCU on the BOM. The 2 MB Flash and 1 MB SRAM give enough headroom for a combined application: a complex motor-control algorithm on the M7 and a fieldbus stack on the M4, for instance. ## Connectivity for industrial gateways and edge nodes With Ethernet, dual CANbus, USB OTG, QSPI, and SAI on the peripheral list, this MCU is sized for a gateway or industrial controller that needs to bridge fieldbus, sensor networks, and a cloud uplink. The 119 I/O in the 176-LQFP package leave room for parallel memory or an external display without a port expander. The data-converter set — 28x16-bit ADC and 2x12-bit DAC — covers multi-channel analog acquisition for motor feedback or sensor arrays. The 176-LQFP (24x24 mm) is a hand-solderable, inspectable package — no BGA rework station needed — but the 0.5 mm pitch still demands careful PCB routing and a clean solder-paste stencil. The supply range of 1.62 V to 3.6 V covers both 1.8 V and 3.3 V logic families, simplifying the power tree.","metaTitle":"STM32H757IIT6 STM32H7 Dual-Core MCU, 2MB Flash, 176-LQFP","metaDescription":"STMicroelectronics STM32H757IIT6 32-bit dual-core ARM Cortex-M4/M7 MCU. 480MHz/240MHz speed, 2MB Flash, 1MB SRAM, Ethernet, dual CAN, 176-LQFP.","metaKeywords":null},"attributes":{"series":"STM32H7","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"240MHz, 480MHz","Series":"STM32H7","Package":"Tray","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":"119","Core Processor":"ARM® Cortex®-M4/M7","Package / Case":"176-LQFP","Product Status":"Active","Data Converters":"A/D 28x16b; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32H757","Program Memory Size":"2MB (2M x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"176-LQFP (24x24)","Voltage - Supply (Vcc/Vdd)":"1.62V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$20.2900","priceTiers":[{"qty":1,"price":"$20.29000","currency":"USD"},{"qty":10,"price":"$18.64700","currency":"USD"},{"qty":25,"price":"$17.87400","currency":"USD"},{"qty":80,"price":"$15.74838","currency":"USD"},{"qty":400,"price":"$14.97543","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/48cd19923653d8f56b6eca00a74feea3.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32H757IIT6/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between STM32H757IIT6 and STM32H743IIT6?","answer":"The STM32H757IIT6 is a dual-core device with both a Cortex-M7 at 480 MHz and a Cortex-M4 at 240 MHz, while the STM32H743IIT6 is a single-core Cortex-M7 at 480 MHz. The dual-core variant adds the M4 core for offloading control or communications tasks, at the cost of slightly different power-management dynamics. Both share the same 176-LQFP footprint and much of the peripheral set, but the H757 requires firmware that manages two cores."},{"question":"Does STM32H757IIT6 support Ethernet and which PHY?","answer":"Yes, Ethernet is listed in the connectivity set. The MCU integrates the MAC layer; you need an external PHY chip (e.g., LAN8720A or DP83848) connected via the RMII or MII interface. The specific PHY selection depends on your speed and isolation requirements."},{"question":"How to program STM32H757IIT6 using ST-Link?","answer":"The STM32H757IIT6 has a standard SWD (Serial Wire Debug) interface. Connect ST-Link's SWDIO, SWCLK, and GND to the corresponding MCU pins, plus VDD from the target board. Use STM32CubeProgrammer or any ARM-compatible debugger to flash the 2 MB internal Flash. The boot from internal Flash is selected with BOOT0 strapped low."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32H757IIT6","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32H757IIT6 when reusing this data.
