Allwinner R6

Cost-effective intelligent dual-mic voice interaction solution

Overview

Allwinner R6 integrates ARM9 architecture that operates at speed up to 600MHz. A 32MB DDR is embedded in Allwinner R6. It realises complete voice function under limited cost, and supports mixed interaction between off-line local command word recognition and on-line cloud ASR recognition. Allwinner R6 includes rich interfaces such as ADC, DAC, I2S/PCM, USB OTG, SD/MMC, UART, SPI, and TWI. Besides, Allwinner R6 supports TINA OS. Allwinner R6 is qualified to industrial standard in white electricity industry.

Highlights

Dual-mic middle-near field intelligent voice interaction

Allwinner R6 integrates ADC, DAC, and I2S/TDM interface, which meets the basic computing rate requirements of dual-mic noise reduction, AEC, wake-up, local command word algorithm, cloud ASR, and IoT interaction. Allwinner R6 is an ideal choice of middle-near field voice interaction solution.

Low cost, low power consumption, easy to develop

Allwinner R6 is highly integrated, which not only keeps the BOM development cost low but also simplifies the overall development process, making it more efficient and less time-consuming for engineers and developers.
