**82C281/282 Cache Sx/AT (386SX) <08/22/91
***Notes:...
***Info:...
***Configurations:...
***Features:
o Flexible DRAM Banks Configuration
- The 82C281/2 supports 256K, 1M, and 4M memory devices, total
main memory size can be up to 16MB. A total of 12 different
memory configurations are supported.
o Page Mode Operation
- Based on the memory configuration shown above [see datasheet],
the memory control unit inside the 820281/2 performs page mode
of operation with a varying block size of 1k, 2k, or 4k bytes
for 256k, 1M, or 4M DRAMs respectively.
o System BIOS Shadow RAM
- The 820281/2 memory control unit provides shadow RAM feature for
several areas of memory system BIOS, video BIOS, and adapter
BIOS.
o Memory Remapping
- If shadow RAM feature is not utilized for the memory area
between 0D0000H - 0EFFFFH, then memory remapping is possible.
The local DRAM areas, 0A0000H - 0BFFFFH and 0D0000H - 0EFFFFH, a
total of 256 KByte, are remapped to the top of total system
memory. The areas for 0F0000H-0FFFFFH (system BIOS) and
0C000H-0CFFFFH (Video BIOS) are reserved for shadow RAM purpose.
o Flexible Multiplexed DRAM Address
o Cache Control Subsystem
- Direct-mapped posted write cache control function provides a low
cost alternative to enhance the system performance by up to 50%.
In order to simplify the design without increasing the system
cost or decreasing performance, the 82C281/2 has been designed
to support only non-pipeline mode for systems with cache memory.
The 82C281/2 offers the following cache control features:
- Flexible Cache Memory Size
- 4MB Cacheabie main memory by using 16KB low cost SRAM.
- 8MB Cacheable main memory by using 32KB low cost SRAM.
- Cache 16MB main memory by using 64KB low cost SRAM.
- Increase the cache size beyond 64KB up to 512KB
- Cache Line Size 4 Byte
- Burst mode memory prefetch is supported by the 82C281/2.
During cache read miss cycles, the memory control subsystem
will perform two consecutive read cycles to fetch 4 bytes
from main memory before terminating the cycle by sending
RDYO# signal to 3868X.
- Non-Cacheable Area
The non-cacheable areas are predefined as indicated below:
- I/O address space
- memory address between 0A0000H and 0FFFFFH.
- any memory address beyond the current configured memory
size.
- programmable non-cacheable memory area as defined by
82C281/2 internal registers.
- 82C281 Posted Write Cache
- The 820281 supports flexible direct-mapped cache with posted
write through update of main memory. By programming the
internal register, the post write control signals are
provided by the 820281 to support a one level write buffer.
With posted write, the CPU write cycles can be completed in
2 CPU T-States, thereby increasing system performance.
- 820282 Write Through Cache
- The 820282 supports a write-through cache system which
allows the designer to reduce system cost by eliminating two
F244's and two F373‘s with only a slight reduction in system
performance (5-10%).
- AT Bus Control
- The 820281/2 AT bus control unit handles all of the AT bus
operations and the DMA/Refresh arbitration. The AT bus
control unit supports the following features:
- Programmable AT Bus Clock - The AT bus clock, ATCLK. can
be programmed as CLK2/6, which is default, or CLK2/4.
- Turbo Switch - The 820281/2 provides a turbo switch
feature that allows users to change the system clock
speed. A programmable bit will enable or disable this
turbo function. When the turbo function is enabled by
setting reg[14H], bit[1] to 1, the 82C281/2 turbo pin
then determines the system clock speed. A low on the
turbo pin forces the CPU to run at the current AT bus
speed which IS CLK2/6 or CLK2/4.
