 • ATJ227X is a highly integrated SOC for high density media solution with multiprocessor. The architecture of one 32-bit RISC up to 450 MHz, cooperated with a powerful Video Engine, a build in Graphics Processing Unit (GPU) and a Display Engine, high efficiency buses, high-speed DDR/DDRII/Mobile DDR memory controller. It can achieve high performance and low power dissipation.
 • ATJ227X is capable of dealing with all formats of video decoder, up to HD resolution, as well as all audio formats with a build in audio codec. And its video recorder can support up to 720p resolution. Audio/Video file can be played through High Definition Display Interface, CVBS, YPbPr, 5.1 channel, SPDIF, IIS. ATJ227X also has RGB and CPU LCD interfaces with touch panel build-in. The integrated USB V2.0 (HS) SIE with OTG function enables the platform to act as a host or slave mass storage device at the speed up to 480Mbps. Nand Flash Controller, with build in 8bit/12bit/24bit/40bit ECC, randomizer for TLC nand support. 2-bit SPI Nor (SNor) Flash Controller, SD/MMC/MS card Controller and versatile peripheral serial interfaces (IIC, SPI*2, UART*2, IR, SPDIF, I2S), is able to support various memories, and such functions as Wi-Fi, LAN, Bluetooth, IRC is supported. Moreover, the build in Power Management Unit provides necessary system power and manage internal and external power dissipation to realize lower system cost.
