R11

Competitive small-screen dual-mic voice interaction solution

Overview

R11 integrates a single-core ARM CortexTM-A7 CPU that operates at speed up to 1.2GHz. A 64MB DDR2 is embedded in R11. R11 includes full functions such as dual-mic voice interaction, 720p screen display, slide and touch interaction, and 720p video record. The integrated video engine supports H.264 1080p@30fps decoder and H.264 720p@60fps encoder. Audio subsystem includes integrated audio codec and I2S/PCM/TDM interface. R11 includes rich interfaces such as MIPI CSI, DVP camera interface and RGB/LVDS LCD output. Besides, R11 can support TINA OS and MINI GUI. R11 is qualified to industrial standard in white electricity industry.

Highlights

Dual-mic middle-near field intelligent voice interaction

R11 integrates ADC, DAC, and I2S/TDM interface, supporting FPU and NEON, which meets the requirements of dual-mic noise reduction, AEC, wake-up, local command word algorithm, cloud ASR, and IoT interaction. R11 is an ideal choice of middle-near field voice interaction solution.

720p display and touch interaction

R11 integrates 720p@60fps RGB/LVDS interface and H.264 1080p@30fps video decoder, and supports on-line media playback, TINA OS, and MINI GUI.

Powerful camera functions

R11 integrates MIPI CSI, DVP, 5M ISP, and H.264 720p@60fps encoder, which can implement on-line video calling and image identification function.
