KM01D/KM01N

Overview

The KM01D and KM01N processors are specifically designed for Artificial Intelligence & Internet of Things (AIoT) cameras and other smart terminal applications, supporting advanced applications such as object detection, object tracking, facial recognition and intelligent video surveillance. Equipped with the ARM926EJ-S core, the KM01D and KM01N processors integrate a Neural Network Processing Unit (NPU), an Image Signal Processor (ISP), and an H.265/H.264 video encoder, delivering 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, TWI and I2S, ensuring high extensibility and flexibility for diverse system designs.
