**SL9020 Data Controller <Jan90
***Info:
The SL9020 Data Controller is a member of VIA's FlexSet family that
efficiently integrates the PC / AT system logic.
The SL9020 is part of the Core AT Logic chips that implement the
system logic which is common to all microprocessors such as 80286,
80386SX, 80386DX and 80486-based PC / AT designs and supports up to 25
MHz performance. In addition to the SL9020, the Core AT Logic chips
consists of the SL9011 System Controller, the SL9025 Address
Controller, the SL9030 Integrated Peripheral Controller and the SL9X5X
Memory Controller.
It is designed using advanced 1.5 micron, double layer metal CMOS
process and is offered in a 100 pin plastic flatpack package.
The SL9020 provides the data buffer latches and drivers for a 16-bit
data path for PC/ AT using 80286 and 80386SX type processor. Two
SL9020 can be used to construct a 32-bit data path for PC/ AT's using
an 80386DX microprocessor.
Control logic and drivers for the chip includes CPU Data Bus (D Bus),
Memory Data Bus (MD Bus), System Data Bus (SD Bus) and Peripheral Data
Bus (XD Bus). The SL9020 also performs parity generation/ checking,
low to high byte transfer on SD Bus and drivers for low and high byte
Column Address Strobes (CAS) for two independent memory banks. Latched
CPU Byte enable (BHE0 & BHE1) are also provided.
All Data bus outputs are capable of high drive (12-24mA) and have fast
rise & fall times of 5ns.
Latches are also provided on D to MD, MD to D, and SD to D paths.
