Each 8bit interface supports one channel of 4M(2560*1440) time division multiplexing input through 148.5MHz double-edge sampling or 297MHz single-edge sampling. Total support for real-time video input. The 16bit interface supports 148.5MHzBT.1120 standard mode, real-time video input and video output interface supports one HDMI1.4b HD output interface, and the maximum output supports one VGA HD output interface.The maximum output supports two independent high-definition output channels (DHD0, DHD1), which can be output through any high-definition interface (HDMI, VGA). DHD0 supports 36-picture output, and the maximum output supports 16-picture output. One CVBS SD output interface supports three full-screen GUI graphics layers of ARGB1555 or ARGB8888, which are used for 2-way HD and 1-way logo respectively. The format is ARGB1888.The maximum resolution is 256×256 audio interface, 3 unidirectional I2S/PCM interfaces, 2 inputs, 16-channel compound input and 1 output, 2-channel output, 16bit voice input and output network interface, 1 Gigabit Ethernet interface, RGMII, RMII and MII interface modes, 10/100Mbit/s half-duplex or full-duplex and 1000Mbit/s full-duplex and TSO. Reduce CPU overhead. Two SATA3.0 peripheral interfaces support PM function, two USB2.0HOST interfaces support eSATA2, and three UART interfaces support Hub function, one of which supports 4-wire and one SPI interface. Two chip selections, one IR interface, one I2C interface, multiple GPIO interfaces, one memory interface, one 32bitDDR3SDRAM controller interface, the highest frequency of 933MHz, ODT function, the maximum capacity of 2GB, automatic power control, SPINOR/NANDFlash interface, 1, 2, 4-wire Spinor/NAND flash, two chip selections, Different types of Flash can be connected separately. For SPINORflash, the maximum capacity of each chip is 64MB. For SPINANDflash, the maximum capacity of each chip is 512MB. For SPINANDflash, the 2KB/4KB page size is supported.
