AK3918AV100E

Product Description

The AK3918AV100E series processors are specifically designed for Artificial Intelligence & Internet of Things (AIoT) cameras. The optimized image signal processor (ISP) and video processors, along with the Neural-network Processing Unit (NPU), enable powerful image processing capabilities, low-bit-rate video encoding and AI applications such as object detection and tracking, face detection and recognition—all while maintaining minimal power consumption. Besides, the secure boot function safeguards firmware integrity and ensures trusted system startup. Additionally, the processors offer a comprehensive set of peripheral interfaces, such as PDM, I2S, TWI, UART, SPI, MMC/SD/SDIO, Ethernet and USB 2.0, providing high extensibility and flexibility.
