The M7 handles number-crunching or protocol stacks; the M4 takes deterministic I/O and low-latency interrupt service. Both share the 1 MB Flash and 1 M x 8 RAM, so the memory budget needs to cover both firmware partitions. ## Flash and RAM — sizing the firmware split With 1 MB of Flash and 1 M x 8 of RAM, this part sits in the mid-density tier of the STM32H7 family. The M7 typically runs the main application and can chew through Flash quickly; the M4 handles housekeeping and real-time loops. The 128 I/O count gives plenty of headroom for parallel buses, display interfaces, and sensor arrays — the 176+25 UFBGA (10x10 mm) packs it all into a compact BGA that needs fine-pitch assembly but saves board area. ## Temperature range and supply — industrial fit The supply range of 1.62 V to 3.6 V lets it run from a single 3.3 V rail or a 1.8 V core supply with separate I/O voltage — flexible for mixed-voltage designs. ## Connectivity and peripherals — what is on the bus The 36-channel 16-bit ADC and dual 12-bit DAC handle analog front-end tasks without an external converter. Internal oscillator means you can boot without a crystal, though an external clock improves accuracy for time-sensitive protocols like Ethernet or USB. ## Lifecycle — active, no LTB pressure ST lists the STM32H745IGK6 as Active. For new designs this is a green light; for production lines the supply channel is stable through independent distribution.","metaTitle":"STM32H745IGK6 STM32H7 Dual-Core MCU, 240/480 MHz, 1 MB Flash","metaDescription":"STMicroelectronics STM32H745IGK6 32-bit dual-core ARM Cortex-M4/M7 MCU. 240 MHz/480 MHz, 1 MB Flash, 1M x 8 RAM, 128 I/O, -40°C 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":"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":"128","Core Processor":"ARM® Cortex®-M4/M7","Package / Case":"201-UFBGA","Product Status":"Active","Data Converters":"A/D 36x16b; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32H745","Program Memory Size":"1MB (1M x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"176+25UFBGA (10x10)","Voltage - Supply (Vcc/Vdd)":"1.62V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$14.7061","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/d0386c46bc62691b70d4ef5acf2dfd75.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the core architecture of STM32H745IGK6?","answer":"It is a 32-bit dual-core device with an ARM Cortex-M4 running at 240 MHz and an ARM Cortex-M7 running at 480 MHz.
