**CS8238 CHIPS/280 & 281 (386 MCA)(82C321/322/325/223/226) c:Aug89
***Info:
CHIPS/280 is a 7-device, enhanced CMOS implementation of most of the
system logic necessary to implement personal computers compatible to
IBM PS/2 Model 70/80. CHIPS/280 enables OEMs to offer compatible PS/2
models 70/80, that are more integrated and superior in performance
than IBM's Model 70/80.
CHIPS/280 includes the CS8238 System Logic CHIPSet, the 82C607
Multi-Function Controller with Analog Data Separator and 16550
compatible serial port, and the Enhanced Gate-Level Compatible
82C451/452 VGA chip as indicated in Figures 1a and lb [see data
sheet]. With these 7 VLSI devices, it requires only 59 additional
components plus memory to implement compatible PS/2 Models 70/80
superior to IBM's models.
CHIPS/280 is designed to maximize the performance of the 80386
microprocessor by coupling it to a high performance page/interleaved
memory sub-system. The maximum page size supported by the CHIPS/280
architecture is 16 KBytes when 1 Mbyte DRAMs are used (16 MB of
onboard Memory) and the four way interleaved mode of operation is
selected. When executing within a page, the DRAM memory sub-system can
execute at the same speed as the processor. To the 386, the mem- ory
sub-system appears as a 16 KByte direct mapped cache, using relatively
inexpensive DRAMs. When operating at 16, 20 or 25 MHZ, the average
waitstate incurred is less than 0.7. Additionally, by using Shadow RAM
techniques, the BIOS code can also be executed with near zero wait
states.
In addition to the high performance memory interface, CHIPS/280
supports a fast Matched Memory Cycle reducing the access time from 200
ns to 120 ns at 25 MHz. CHIPS proprietary Fast VGA cycle allows VGA
I/O accesses to be performed within 187.5 ns@ 16 MHz, 150 ns @ 20 MHz,
and 120 ns @ 25 MHz.
Regardless of the CPU speed, the DMA controller operates at 10
MHz. Once the DMA and the peripherals are tuned, for example, with a
1:1 interleaving on the Hard Disk, CHIPS/280 continues to deliver
dependable high performance.
