Running the core at 180 MHz from the internal oscillator or an external crystal means the flash wait state count needs bumping to at least 1 before raising the core clock past around 30 MHz, or the first branch instruction hard-faults. The PLL can be fed from the HSI or HSE; the 180 MHz ceiling is the SYSCLK limit, not the APB1/APB2 bus speeds, which are prescaled down from the AHB clock. The 256 KB SRAM is split across up to four memory blocks — the DTCM and ITCM regions give single-cycle access for time-critical interrupt handlers. ## 201-UFBGA — what the package drives on the board The 201-UFBGA (176+25 UFBGA 10x10 mm) is a fine-pitch BGA with 0.5 mm ball pitch. That ball pitch forces at least a 4-layer PCB with microvias or via-in-pad for fanout on the inner rows — a 2-layer board will struggle to route the 140 I/O plus the Ethernet PHY interface and the FMC bus for external memory. The 10x10 mm body keeps the footprint compact, but the rework profile needs a preheat soak to avoid cold joints on the center balls. For a production BOM that already qualifies this package variant, there is no urgency to requalify a second source — though the STM32F429IET6 (same package, larger Flash) is pin-compatible if the firmware image outgrows the 512 KB allocation.","metaTitle":"STM32F429IEH6 STM32F4 ARM Cortex-M4 MCU, 180 MHz","metaDescription":"STM32F429IEH6 32-bit ARM Cortex-M4 MCU at 180 MHz with 512 KB Flash, 256 KB RAM, 140 I/O, LCD controller, Ethernet, CAN, USB OTG, in 201-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":"Tray","RAM Size":"256K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, I²S, LCD, 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":"201-UFBGA","Product Status":"Active","Data Converters":"A/D 24x12b; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32F429","Program Memory Size":"512KB (512K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"176+25UFBGA (10x10)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$17.6200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/fa3522ede21a921b5dbbcb78f05a0a95.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F429IEH6/alternatives.json"},"ai":{"faq":[{"question":"Is STM32F429IEH6 compatible with STM32F429IET6?","answer":"Yes, the STM32F429IET6 is pin-compatible in the same 201-UFBGA package but carries 2 MB of Flash instead of 512 KB.
