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)
