AK3918EV200

Product Description

The AK3918EV200 series processors are specifically designed for Internet of Things (IoT) cameras, a key component in cost-sensitive electronic surveillance systems. Equipped with an image signal processor (ISP), an H.264 encoder, and a hardware-accelerated AES/DES/3DES encryption engine, the AK3918Ev200 series processors deliver efficient image processing and high-efficiency, high-fidelity video encoding at ultra-low power consumption, all while ensuring data security. The AK3918EV200 series processors integrate a 512Mibit DDR2 SDRAM, Wi-Fi, and BLE, thus reducing the bill-of-materials (BOM) cost of end products. Additionally, the AK3918EV200 series processors provide a wide range of peripheral interfaces, including MMC/SD/SDIO, Ethernet MAC, USB2.0, UART, SPI, TWI and I2S, ensuring high extensibility and flexibility for diverse product designs.
