R818 Datasheet | Allwinner

Overview 1. Overview R818 is a high performance quad-core application processor for audio application markets. The application processor incorporates a high efficient 64-bit quad-core Cortex TM-A53 processor, advanced Imagination Power VR GE8300 GPU, 13M camera ISP, and high-definition 4K@30fps video decoder. An extensive set of audio interfaces such as audio codec, I2S/PCM, DMIC, one wire audio (OWA) are included for microphone voice wake-up/recognition/record/playback applications on connected audio products. Rich memory interfaces (DDR4, DDR3, DDR3L, LPDDR3, LPDDR4, e MMC, Nand) provide high flexibility to support variant memory configurations. Lots of high-performance interfaces can get very flexible solution, such as MIPI CSI, MIPI DSI, EMAC, USB, UART, SPI, PWM, TWI, LEDC, etc. The Allwinner SDK features high stability and ease of use, supports rapid mass production.
