OVERVIEW
The Allwinner A33 is a remarkably power-efficient quad-core tablet processor based on ARM Cortex
TM
-A7 CPU
along with Mali400MP2 GPU architecture. It is also highly competitive in terms of system cost thanks to its high
system integration and is capable of delivering excellent user experience while maintaining ultra low power
consumption.
Main features of A33 include:
●
CPU architecture: A33 processor packs the most power efficient quad-core Cortex
TM
-A7 CPU architecture deliver
outstanding system performance and impressive battery life experience;
●
Graphic: A33 adopts the extensively implemented and technically mature Mali400MP2 GPU to provide end users
with superior experience in web browsing, video playback and games, etc.; OpenGL ES 2.0 and OpenVG 1.1
standards are supported;
●
Video Engine: A33 supports high-definition 1080P video processing and various mainstream video standards
such as H.264, VP8, MPEG 1/2/4, JPEG/MJPEG, etc.;
●
Display: A33 supports CPU/RGB/LVDS LCD interface up to 1280x800 resolution. Four-lane MIPI DSI (Display
Serial Interface) is integrated as well, supporting MIPI DSI V1.01 and MIPI D-PHY V1.00;
●
Image: A33 supports a parallel CMOS sensor interface up to 5M resolution
Thanks to its advanced system design and outstanding software optimization, the A33 is capable of providing top-
notch system performance with long-lasting battery life experience: in addition to its powerful yet energy-efficient
Cortex
TM
-A7 CPU architecture, advanced fabrication process, video acceleration hardware, DVFS technology
support and high system integration, A33 also features a unique Talking Standby Mode where the processor can
be inactive during voice calls to provide end users with ultra-long battery life experience. Additionally, Allwinner A33
features high system integration with a wide range of integrated I/Os like 4-lane MIPI DSI, LVDS, USB Dual Role
Device,USB Host,SD/MMC, I2S /PCM, SPI, thus significantly reducing system components required in design to
simplify product design and reduce total system costs.
