Quad-Core
Industrial Control Processor
The A40i processor represents Allwinner’latest achievement in the intelligent industrial control
s
sector. The processor is ideal for applications that require 3D graphics, advanced video processing,
rich user interfaces, high quality, low power consumption and a high level of system integration.
The A40i is mainly applied to industrial control products based on visual interaction.
Content can be displayed on either 4-lane MIPI DSI displays, an RGB panel or a Dual-channel
LVDS panel. CVBS-out and HDMI V1.4 is also supported.
Supports dual CMOS sensor parallel interfaces and 4-channel CVBS-in , which is capable of
executing multi-channel video recording.
A40i meets the standard of industrial grade, and the operating temperature reaches the
standard of AEC-Q100 grade3.
Integrated audio codec with 24bit/192KHz DAC playback, and supports I2S/PCM interface for
connecting to an external audio codec.I2S/PCM interface includes eight channels of TDM
with sampling precision up to 32bit/192KHz.
To reduce the total system cost, the A40i has an extensive range of support for hardware
peripherals allowing for an array of configurations, such as 3*USB2.0, GMAC, EMAC, SATA,
2*TSC, PS2, RTP, 4*SDHC etc.
Supports Linux3.10, Android 7.1 and the above system.
