YGV617B

The YGV617B is designed as the built-in PLL circuit which allow to superimpose the images outputted by the device over a external video signals easier. Since this device has a high speed drawing function and character draming function and is able to specify vertical and horizontal size of the screen optionally, it is applicable to controlling display units such as a wide screen TV and liquid crystal displays.

Features of the YGV617B are:(1)bit map plane is able to display images simultaneously using 16 colors, 256 colors or 32768 colors;(2)a sprite is able to use 32 x 32 dots;(3)the sprite plane can be used as a crosshair line cursor;(4)register and various I/O ports are mapped on the 16 byte I/O space;(5)one unit of 4 M or 16 M DRAM with 16 bit configuration can be connected;(6)the built-in FIFO for display data has reduced overhead at draw data access;(7)CMOS and 5 V single power supply;(8)144 pin plastic SQFP.

The absolute maximum ratings of the YGV617B can be summarized as:(1)supply voltage: -0.5 V to +7.0 V;(2)input terminal voltage: -0.5 V to VDD+0.5 V;(3)output terminal voltage: -0.5 V to VDD+0.5 V;(4)output terminal current: -20 to +20 mA;(5)storage temperature: -50 to +125 .
