The NXP i.MX6ULL is a low-power ARM Cortex-A7 processor designed for industrial control and IoT edge computing. With its cost-effectiveness and rich peripheral interfaces, it plays a significant role in embedded applications. Built on a 40nm process, this single-core processor operates at up to 900MHz, supports low-power modes (as low as 150mW), and is ideal for cost-sensitive applications requiring stable performance.
The ARMxy SBC Series BL310 ARM Embedded IOT Gateway use NXP i.MX6ULL SoC, with flexible ROM/RAM and I/O, use for IOT Edge Devices, IoT Gateways, and Industrial Automation, etc.
