AK3918A Series

AK3918AV130
Product Description

The AK3918AV130 series processors are specifically designed for Artificial Intelligence & Internet of Things (AIoT) Cameras. Built on a dual-core architecture, the processors integrate an Image Signal Processor (ISP), video encoders, and Neural Network Processing Unit (NPU), enabling 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 processors are able to achieve even lower power consumption in shallow sleep mode, further improving energy efficiency. In terms of security, the AK3918AV130 series processors feature a robust security engine that supports secure boot and data encryption, enhancing overall system protection. Additionally, a comprehensive set of peripheral interfaces, including UART, SPI, MMC/SD/SDIO, TWI, Ethernet MAC and USB2.0, endows the AK3918AV130 series processors with high extensibility and flexibility.
