The Flash density supports over-the-air update staging with a backup image, while the SRAM covers packet buffers and control data. For designs that need more scratchpad, the EBI/EMI interface can connect external SRAM or NOR Flash without a glue-logic FPGA. ## Peripheral set — Ethernet, CAN, and analog Built-in Ethernet MAC and CANbus controllers eliminate the need for external PHY-management MCUs or CAN transceiver controllers, reducing BOM count and board area. ## Package and layout — 176-UFBGA (10x10) That compact footprint saves significant board area versus a 144-pin LQFP, but requires a multi-layer PCB with via-in-pad or microvias for fan-out. The BGA also demands a stencil and reflow oven — not hand-solderable. For dual-sourcing resilience, ST's STM32F4 family includes pin-compatible density variants — the STM32F429 adds a TFT LCD controller and the STM32F437 adds a cryptographic accelerator — but the STM32F427IIH7 itself is not cross-referenced to a second-source vendor.","metaTitle":"STM32F427IIH7 32-bit ARM Cortex-M4 MCU, 180MHz, 2MB Flash","metaDescription":"STM32F427IIH7 32-bit ARM Cortex-M4 MCU at 180MHz with 2MB Flash and 256KB SRAM. 140 I/O, Ethernet, CAN, 12-bit ADC/DAC. -40°C to 105°C.","metaKeywords":null},"attributes":{"series":"STM32F4","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"180MHz","Series":"STM32F4","Package":"Tray","RAM Size":"256K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, I²S, POR, PWM, WDT","Connectivity":"CANbus, EBI/EMI, Ethernet, I²C, IrDA, LINbus, SPI, UART/USART, USB OTG","Mounting Type":"Surface Mount","Number of I/O":"140","Core Processor":"ARM® Cortex®-M4","Package / Case":"176-UFBGA","Product Status":"Active","Data Converters":"A/D 24x12b; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32F427","Program Memory Size":"2MB (2M x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 105°C (TA)","Supplier Device Package":"176-UFBGA (10x10)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$20.8200","priceTiers":[{"qty":1,"price":"$20.82000","currency":"USD"},{"qty":10,"price":"$19.13700","currency":"USD"},{"qty":25,"price":"$18.34360","currency":"USD"},{"qty":168,"price":"$16.16220","currency":"USD"},{"qty":336,"price":"$15.36899","currency":"USD"},{"qty":504,"price":"$14.37744","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/fa3522ede21a921b5dbbcb78f05a0a95.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F427IIH7/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between STM32F427IIH7 and STM32F429IIH7?","answer":"Both are 180 MHz Cortex-M4 MCUs in the same 176-UFBGA package with identical Flash and SRAM.
