That dual-core architecture lets one core handle real-time control loops or sensor fusion while the other manages the wireless stack or data logging — no context-switching overhead. For a design that needs deterministic response on one thread and throughput on another, this avoids the scheduler tax a single-core part would pay. Program memory is 1 MB of Flash, sized for complex firmware with over-the-air update capabilities; the 560 KB SRAM holds large audio buffers, image frames, or protocol stacks without external memory. The 50 general-purpose I/Os, combined with eMMC/SD/SDIO, USB, I²C, SPI, and UART/USART, cover peripheral-rich applications like wearable gateways, portable medical devices, and industrial IoT edge nodes. ## Industrial temperature and wide supply — deployment envelope Rated -40°C to 105°C ambient, this MCU fits outdoor telecom cabinets, engine-bay controllers, and factory-floor automation where the enclosure sees thermal cycling. The supply range spans 0.72 V to 3.6 V. ## Package and assembly constraints Housed in a 121-ball CTBGA (8x8 mm), this is a fine-pitch BGA. That means the PCB requires controlled via-in-pad or microvia fanout, and assembly needs X-ray inspection for solder-joint verification. ## Lifecycle and sourcing posture ROHS3 compliant. For volume BOM commitments, this part is specified into new designs with confidence; no forced migration horizon.","metaTitle":"MAX32666GXMBL+ ARM Cortex-M4F Dual-Core MCU, 96MHz","metaDescription":"Maxim MAX32666GXMBL+ DARWIN dual-core ARM Cortex-M4F MCU at 96MHz, 1MB Flash, 560KB SRAM, 121-CTBGA, -40 to 105°C.","metaKeywords":null},"attributes":{"series":"DARWIN","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Speed":"96MHz","Series":"DARWIN","Package":"Tray","RAM Size":"560K x 8","Core Size":"32-Bit","Peripherals":"Brown-out Detect/Reset, DMA, I²S, POR, PWM, WDT","Connectivity":"eMMC/SD/SDIO, I²C, SPI, UART/USART, USB","Mounting Type":"Surface Mount","Number of I/O":"50","Core Processor":"ARM® Cortex®-M4F","Package / Case":"121-LFBGA","Data Converters":"A/D 8x10b Sigma-Delta","Oscillator Type":"External, Internal","lifecycle_stage":"eol_hot","Program Memory Size":"1MB (1M x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 105°C (TA)","Supplier Device Package":"121-CTBGA (8x8)","Voltage - Supply (Vcc/Vdd)":"0.72V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$14.49","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$14.49000","currency":"USD"},{"qty":10,"price":"$13.31400","currency":"USD"},{"qty":25,"price":"$12.76200","currency":"USD"},{"qty":80,"price":"$11.24425","currency":"USD"},{"qty":348,"price":"$10.69236","currency":"USD"},{"qty":696,"price":"$10.00253","currency":"USD"},{"qty":1044,"price":"$9.17474","currency":"USD"}]},"links":{"datasheetUrl":"https://datasheets.maximintegrated.com/en/ds/MAX32665-MAX32668.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is MAX32666GXMBL+ compatible with 3.3V logic?","answer":"Yes.
