**82C496/7 DXBB PC/AT Chipset (Cached) <01/16/92
***Info:
The OPTi 82C497 is a Direct Mapped Write Back cache controller with
one level write buffer that is an optional part of the DXBB (Building
Block) Chip set. The DXBB also contains the 82C496 and the 82C206,
which form the heart of the system. The 82C497 is added to the DXBB
chip set for cache based systems.
The OPTi 82C496 offers an upgradable CPU module base-board solution
for the 80386 or the 80486 PC/AT system. By swapping the CPU module,
the vendor can configure the 82C496 driven base-board into various
32-bit AT systems - 386 or 486 CPU, with cache or without cache and
rated at 16MHz- 50MHz.
For the Non-Cache systems, the CPU interfaces directly with the 82C496
and the local devices, like the local VGA controller or the local hard
disk adaptor.
For cache based systems the 82C497 (the cache controller) sits between
the CPU and the 82C496 and the local devices. All the high frequency
signals are isolated by the 82C497. This allows the base-board to run
at a fixed speed (25 or 33MHz) - while the CPU and the Cache can run
synchronously at any determined rated speed. This provides a reliable
upgrade method for the CPU modules.
***Configurations:...
***Features:
o 386 and 486 CPU interface
o Isolates the CPU bus from Local bus, more reliable system
operation at high speed
o Asynchronous handshaking between CPU bus and Local bus; fixed
base-board speed with upgradeable CPU card speed
o Direct map write back cache with one level write buffer and
16-byte line size
o Programmable 2-1-1-1, 3-1-1-1, 2-2-2-2 or 3-2-2-2 burst read cycle
o Programmable cache write hit 0 or 0 wait state
o Optional Dirty bit
o Supports 32K - 256K cache size for 386 cache system
o Supports 64K - 512K cache size for 486 cache system
o Provides TAG and Dirty RAM test capability
o Built-in TAG auto-invalidation circuitry
o Two programmable non-cacheable regions
o Option for write-protected, cacheable Video BIOS
o Cacheable AT bus memory space
o 8042 emulation for fast CPU-reset and gate A20 generation
o 1X clock source support for systems from 16 MHZ to 50 MHZ
o 160-pin plastic quad flat package
