The 114 GPIOs, LCD controller, Ethernet MAC, and dual 12-bit DACs put this part squarely in the human-machine-interface and connectivity tier: think touch-screen panels, industrial gateways, and embedded vision systems where you need a display and a network stack on a single chip. ## 180 MHz Cortex-M4 — bus margin and memory headroom The 2 MB Flash is large enough to hold a full embedded display framebuffer plus application code without external memory for many designs. The 256 KB SRAM handles the typical Ethernet and USB buffers, but if you are running a high-resolution TFT with double buffering, budget for external SDRAM over the flexible memory controller. The 12-bit ADC bank (24 channels) and dual 12-bit DACs cover analog front-end tasks without an external converter. ## Industrial temperature, active lifecycle The product status is Active, and it carries ROHS3 compliance. The 143-WLCSP is a direct-attach package with no leads and no exposed paddle — the solder balls are the only mechanical and electrical connection. That means the PCB land pattern must match the 4.52 x 5.55 mm ball array exactly, and rework requires a hot-air station with a fine nozzle and a preheat plate to avoid warping the thin substrate. Underfill is recommended for any product that sees vibration or thermal cycling.","metaTitle":"STM32F429ZIY6TR STM32F4 MCU, ARM Cortex-M4 180MHz, 2MB Flash","metaDescription":"STM32F429ZIY6TR 32-bit MCU with ARM Cortex-M4 core at 180MHz, 2MB Flash, 256KB RAM, LCD controller, Ethernet, industrial temp -40°C to 85°C, 143-WLCSP package.","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":"Tape & Reel (TR) Cut Tape (CT)","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":"114","Core Processor":"ARM® Cortex®-M4","Package / Case":"143-UFBGA, WLCSP","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":"2MB (2M x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"143-WLCSP (4.52x5.55)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$15.1000","priceTiers":[{"qty":1,"price":"$15.10000","currency":"USD"},{"qty":10,"price":"$13.87400","currency":"USD"},{"qty":25,"price":"$13.29920","currency":"USD"},{"qty":100,"price":"$11.71770","currency":"USD"},{"qty":250,"price":"$11.14260","currency":"USD"},{"qty":500,"price":"$10.42372","currency":"USD"},{"qty":1000,"price":"$9.56107","currency":"USD"},{"qty":5000,"price":"$8.91408","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/fa3522ede21a921b5dbbcb78f05a0a95.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F429ZIY6TR/alternatives.json"},"ai":{"faq":[{"question":"What is the closest functional second-source for STM32F429ZIY6TR?","answer":"For a true second source within the STM32F4 family, look at the STM32F429IIT6 in LQFP-176 if you need more I/O and can trade the WLCSP footprint for a larger package.
