The 130 I/O lines in the 169-UFBGA package let you bring out the EBI/EMI bus for an external display or SRAM expansion while keeping sensor and actuator channels available. ## Connectivity peripherals — single-chip gateway capability That peripheral set lets a single STM32F427AIH6TR serve as a protocol gateway between an industrial Ethernet fieldbus, a CAN-based actuator network, and a USB-connected HMI — no external bridge chip needed. ## 169-UFBGA package — layout considerations For designs that only need 80–100 signals, a 2-layer board with through-hole vias is feasible if the decoupling caps sit close to the BGA perimeter.","metaTitle":"ST STM32F427AIH6TR ARM Cortex-M4 MCU, 180MHz, 2MB Flash","metaDescription":"STMicroelectronics STM32F427AIH6TR 32-bit ARM Cortex-M4 MCU at 180MHz with 2MB Flash, 256KB SRAM, Ethernet MAC, CAN, USB OTG in 169-UFBGA.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"180MHz","Series":"STM32F4","Package":"Tape & Reel (TR)","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":"130","Core Processor":"ARM® Cortex®-M4","Package / Case":"169-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~85°C(TA)","Supplier Device Package":"169-UFBGA (7x7)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$13.8075","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/16841ebcacf268e62dcd4a8bbbfb1ed2.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F427AIH6TR/alternatives.json"},"ai":{"faq":[{"question":"What is the core of STM32F427AIH6TR?","answer":"The core is an ARM Cortex-M4 running at 180 MHz, with a 32-bit single-core architecture and hardware floating-point unit for DSP tasks."},{"question":"What are the alternatives to STM32F427AIH6TR?","answer":"Within the STM32F4 family, pin-compatible alternatives exist across the density and package options — for example, the STM32F429 variant adds a TFT LCD controller but shares the same 169-UFBGA footprint.
