YGV628B






□ Digital Image Input/Output Function
● Corresponding to 18bit RGB, 16bit YCrCb422, and ITU656.
● By YS bit output, Mixing with an image signal are possible externally.
□ Analog Image Output Function
● Analog RGB output which has 8 bits DAC for each R,G,B
● By YS bit output, super-impose of image data is available from an outside.
□ Capture Function
● The depiction from the external image input of 18bit RGB, 16bit YCrCb422, and ITU656 to frame
memory is possible in real time.
● When the digital image input is ITU656, it is possible to select from two systems of asynchronous input.
● Pixel Skipping Functions of Horizontal direction and Vertical direction.
● Interlace Æ Progressive Conversion Function
□ External Memory
● Video Memory
 16Mbit, 64Mbit, 128Mbit, and 256Mbit(x16) of SDRAM are connectable. However, only a half
domain is possible to use at the time of 256Mbits of SDRAM is in use.
 WRITE/READ access by the memory transfer function
 The maximum operating frequency of SDRAM clock is 81MHz.
□ Others
● High flexibility CPU I/F with 16bit CPU bus width and endian control are adopted.
● Built-in register is directly mapped to the 256 Bytes of CPU memory space.
● 176 pin plastic LQFP Pin lead coating is Pb free. (YGV628B-VZ)
● Operating temperature: -40 degree to +85 degree.
● CMOS, 3.3V unity voltage(5V tolerant)
