**CS82310 PEAK/DM 386 AT (82C351/82C355/82C356) c91
***Info:
The CS82310 PEAK/DM CHIPSet is a three chip VLSI implementation of the
systems logic required to implement a cache-based 386DX system. This
CHIPSet is designed to offer a 100% PC/AT compatible Integrated
solution. The flexible architecture of the PEAK/DM allows it to be
used in any iAPX386-based system design such as CAD/CAE workstations,
office systems, industrial and financial transaction systems. The
CS82310 PEAK/DM CHIPSet provides a complete cache based 386/AT system
using only 19 components plus memory devices. The CS82310 PEAK/DM
CHIPSet consists of one 82C351 CPU/cache/DRAM controller, one 82C355
data buffer, and one 82C356 peripheral controller. The CHIPSet
supports a local CPU bus, a 32-bit memory bus, and AT buses.
82C351 CPU/Cache/D RAM/Controller
By integrating both the cache and DRAM control functions in one chip,
the 82C351 supports simultaneous activation of cache and DRAM
accesses; minimizing the cache miss penalty. It has hardware support
to allow the user to designate up to four blocks (of variable size
from 4KB to 4MB) of main memory as non-cacheable address space. The
82C351 cache controller supports a direct mapped cache architecture
and cache sizes of 32KB, 64KB, 128KB, or 256KB. Memory write updates
are implemented using a buffered write-through scheme. The 82C351 is
available in a 160-pin PFP package.
82C355 Data Buffer
The 82C355 bus controller contains the data buffers used to interface
the local and system memory buses and a path for the AT data bus. In
addition to having high current bus drive, it also performs
conversions between the different sized data paths and provides parity
generation and checking. The 82C355 is available in a 120-pin PFP
package.
82C356 Peripheral Controller
The 82C356 peripheral controller contains the address buffers used to
interface between the processor address bus (A<23:2>) and the system
address bus (SA<19:0>). It also contains an equivalent 82C206
integrated peripheral controller that incorporates: two 8237 DMA
controllers, two 8259 interrupt controllers, one 8254 timer/counter,
one MC146818 real time clock, and several TTL/SSI interface logic
chips.

**CS8283 LeAPset-sx (82C841/82C242/82C636) c:Mar90
***Info:
The LeAPset CS8283 CHIPSet comprises highly integrated applications
specific integrated circuits that emulate the control logic of IBM PC
AT-compatible computers. Additionally, this CHIPSet provides
functions designed specifically for the laptop computer environment.
The CS8283 CHIPset, which supports the 386sx microprocessor, comprises
the following devices:
- the 82C841. This device includes a CPU/bus, page/interleave, and EMS
memory controller in addition to some laptop control features
- the 82C242. This chip includes data/address buffers and bus
conversion logic.
- the 82C636. This is the Power Control unit. It controls system power
and provides slow refresh DRAM support in standby mode.
- the 82C206. This device is an integrated peripheral controller.
- the 82C601. This is a multifunction controller that provides one
parallel and two serial port interfaces.
- the 82C455. This is a VGA-compatible flat panel control that
supports CRT, LCD, plasma and electro-luminescent displays.
- the 82C765. This is a floppy disk controller that is compatible
with the pud765A controller. It also contains a precision analog
data separator.
The CS8283 CHIPSet, which is compatible with the NEAT CHIPSet, is
designed specifically for use in laptop computers. However, it can be
used as the basis for a small footprint desktop computer in which
integration is the critical factor. Figure 1.1 [see datasheet] is a
block diagram of a typical implementation of the CS8283 in a laptop
environment.
