TVGA9200CXr

The TVGA9200CXr is a highly integrated and cost effective solution for high performance VGA(video graphics array) systems.The built-in data bus transceiver and feature connector support mean a minimum motherboard solution can be achieved with obly three support chipsLthe TDK8001 truecolor DAC/clock chip,and two pieces 256K x 4 DRAM.Programmable DRAM timing allows the designer to choose either slower speed DRAM for a cost saving solution or faster speed DRAM for high speed performance.Display support for super VGA,EGA,CGA and MDA monitor assures TVGA9200CXr solutions can be matched up with virtually any monitor on the market.The TVGA8900D also provides improved speed over the TVGA8900CL and TVGA8900C.This is achieved by zero-wait state direct memory write ISA bus performance,faster base DRAM clock(48 MHz),and IMB linear addressing.The linear addressing eliminates memory bank switching and increases the speed for software that accesses more than 256K of memory.

The TVGA9200CXr has some features:(1)single-chip solution for IBM PC/AT and compatible,PS/2 and compatible;(2)Built-in data bus transceiver and feature connector support;(3)only one 32Kb EPROM required to achieve 16-bit BIOS operation speed;(4)fully hardware compatible with VGA,EGA,CGA,MDA and hercules at the register level;(5)programmable DRAM timing;(6)requires only two 256K x 4 DRAM chips for VGA solution;(7)160 pin PFP package;(8)high-resolution drivers available;(9)supports 80/132-column text in 25,30,43,or 60 rows;(10)supports linear addressing.

The absolute maximum ratings of TVGA9200CXr can be summerized as:(1)power supply voltage:4.75 to 5.25 V;(2)input voltage:GND to Vdd V;(3)operating temperature:0 to 70°C and (4)storage temperature:-40 to 100°C.
