KM02D/KM02X

Product Description

The KM02D and KM02X processors are specifically designed for Artificial Intelligence & Internet of Things (AIoT) cameras, video door entry units and attendance machines, supporting advanced applications such as object detection, object tracking, facial recognition and intelligent video surveillance. With dual RISC-V cores, integrated Neural Network Processing Unit (NPU), Image Signal Processor (ISP), and hardware H.265/H.264 video encoder, the KM02D and KM02X processors offer efficient image processing and high-efficiency, high-fidelity video encoding at ultra-low power consumption. Besides, the secure boot function safeguards firmware integrity and ensures trusted system startup. Additionally, the processors feature a rich set of peripheral interfaces, including MMC/SD/SDIO, Ethernet MAC, USB 2.0, UART, SPI, PDM, TWI and I2S, ensuring high extensibility and flexibility for diverse system designs.
