The 257-TFBGA (10x10 mm) package with surface-mount assembly suits compact PCBs in motor drives, outdoor telecom, and engine-control modules. Five USB 2.0 ports (two host, three OTG+PHY) cover multiple peripheral connections without external hub chips. The integrated Gigabit Ethernet MAC and 10/100 Mbps support industrial networking stacks. Additional interfaces include CAN, I²C, SPI, UART, MMC/SD/SDIO, SPDIF, and HDMI-CEC, which together address HMI panels, gateway appliances, and edge-compute nodes. ## Security and graphics ARM TrustZone (ARM TZ) provides a hardware-isolated secure environment for boot authentication, key storage, and secure firmware updates. The part includes graphics acceleration and an LCD display controller, making it suitable for embedded GUI applications without a separate GPU. It is ROHS3 compliant.","metaTitle":"STM32MP157AAD3T MPU, 650MHz Cortex-A7 + 209MHz Cortex-M4","metaDescription":"STMicroelectronics STM32MP157AAD3T dual-core MPU: 650MHz Cortex-A7 + 209MHz Cortex-M4, DDR3/LPDDR2/3, USB 2.0, GbE, -40 to 125°C.","metaKeywords":null},"attributes":{"series":"STM32MP1","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"USB":"USB 2.0 (2), USB 2.0 OTG+ PHY (3)","Speed":"209MHz, 650MHz","Series":"STM32MP1","Package":"Tape & Reel (TR); Cut Tape (CT)","Ethernet":"10/100Mbps, GbE","Mounting Type":"Surface Mount","Voltage - I/O":"2.5V, 3.3V","Core Processor":"ARM® Cortex®-A7","Package / Case":"257-TFBGA","RAM Controllers":"DDR3, DDR3L, LPDDR2, LPDDR3","lifecycle_stage":"eol_hot","Co-Processors/DSP":"ARM® Cortex®-M4","Security Features":"ARM TZ","Additional Interfaces":"CAN, Ethernet, I²C, MMC/SD/SDIO, SPDIF, SPI, UART, USB","Graphics Acceleration":"Yes","Operating Temperature":"-40°C ~ 125°C (TJ)","Supplier Device Package":"257-TFBGA (10x10)","Number of Cores/Bus Width":"2 Core, 32-Bit","Display & Interface Controllers":"HDMI-CEC, LCD"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$18.1","priceTiers":[{"qty":1,"price":"$18.10000","currency":"USD"},{"qty":10,"price":"$16.63600","currency":"USD"},{"qty":25,"price":"$15.94680","currency":"USD"},{"qty":100,"price":"$14.05050","currency":"USD"},{"qty":250,"price":"$13.36092","currency":"USD"},{"qty":500,"price":"$12.49892","currency":"USD"},{"qty":1800,"price":"$11.46453","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/b753a652d9a019bd92611ceb631ac803.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32MP157AAD3T/alternatives.json"},"ai":{"faq":[{"question":"Is STM32MP157AAD3T lead-free?","answer":"Yes, the STM32MP157AAD3T is ROHS3 compliant, meaning it meets the lead-free and restricted-substance requirements of the RoHS directive."},{"question":"Are there alternatives to STM32MP157AAD3T in the STM32MP1 family?","answer":"The STM32MP1 series includes multiple variants that differ in core frequency, graphics acceleration, and peripheral count.
