Description
The Plus1 (SP7021) is a revolutionary System-on-Chip (SoC) that delivers Linux-class processing power combined with the integration simplicity of a microcontroller. Jointly developed by Sunplus and Tibbo Technology, the Plus1 is designed from the ground up for the IoT and industrial control markets. It features a rich selection of built-in I/O interfaces and utilizes an easy-to-route package, significantly reducing PCB complexity and manufacturing costs.
Unlike chips used in devices like the Raspberry Pi—which are often repurposed from set-top boxes and not originally designed for IoT applications—the Plus1 genuinely addresses the practical needs of low-to-medium volume products, completely eliminating the manufacturing difficulties associated with BGA packaging. Furthermore, it retains native support for 5V/3.3V GPIOs, effectively resolving the control and interfacing challenges caused by the ultra-low voltages of advanced process nodes. The Plus1 seamlessly blends Linux-level performance with unmatched practicality, making it the ideal tailored solution for smart devices and the industrial control market.
The Plus1 (SP7021) serves as an exceptional platform for industrial automation. By combining low power consumption, high integration, and an abundance of I/Os, it enables a wide array of applications including industrial automation control, water quality monitoring, environmental sensing, and many others. As an ideal alternative to Raspberry Pi and high-end Linux SoCs, the Plus1 eliminates the need for complex BGA packaging, thereby streamlining design workflows and drastically lowering development and maintenance costs. It is the perfect choice for high-mix, low-to-medium volume industrial equipment designs.
