**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.
