Features: OSD Function
The OSD images which is composed of plains in case of a digital image input is overlaid.
Simultaneous use of three plains is possible in AVDP7 at its maximum.
The natural picture display of 65536 colors by R5bit, G6bit, and B5bit. It is the palette color of 256 colors in 16777216 colors.
Supports 16bit YCrCb422
16 gray-levels of -blending in dot units
Conversion of display priority is possible
Display Resolution
Creation of the Display Timing of NTSC, PAL, QVGA, Wide QVGA, VGA, Wide VGA, and SVGA is possible.
Examples of Correspondence Resolution : 320*240, 400*240, 720*240, 640*480, 800*480, 800*600, etc..
Resolution Converting Function : Horizontal direction1/2 times to 8192 times display
Vertical direction1/4 times to 8192 times display.
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 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.

Note 1) Value based on Vss(GND) =0VDescriptionYGV628B (hereafter called AVDP7) is the latest version of YAMAHA AVDP series which has many past successful records in various visual equipments, vehicle equipment, etc.
Three bit-map planes are equipped, and YGV628B can be displayed in piles to an external image; furthermore, AVDP7 has many functions as OSD (On Screen Display), such as -blending, change of a display priority, etc. In addition, it has a digital image Input/Output function to allow an external image to be expanded or reduced.
Moreover, AVDP7 is supports to the resolution up to SVGA, and YGV628B is possible to apply to the various digital equipments only by connecting one SDRAM to an external memory as a frame memory.
