KM Series

KM01W

Overview

The KM01W processor is specially designed for Artificial Intelligence & Internet of Things (AIoT) cameras of Always-on Video (AOV) applications and AI glasses.

The optimized image signal processor (ISP) and video processors, and Neural-network Processing Unit (NPU), enable powerful image processing capabilities, low-bitrate video encoding and AI applications such as object detection and tracking, face detection and recognition—all while maintaining minimal power consumption. Notably, the KM01W processor is able to achieve even lower power consumption in shallow sleep mode, making it ideal for AOV applications. The built-in wireless module, supporting 2.4GHz and 5GHz Wi-Fi 6, as well as Bluetooth Basic Rate/Enhanced Data Rate (BR/EDR) and Bluetooth Low Energy (BLE) modes, provides reliable and high-speed wireless transmission. In terms of security, the secure boot function safeguards firmware integrity and ensures trusted system startup. Additionally, the processor offers a comprehensive set of peripheral interfaces, such as PDM, UART, SPI, I2S, MMC/SD/SDIO, Ethernet MAC and USB 2.0, providing high extensibility and flexibility.
