**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.

***Info:
The CHIPS 82C721 enhanced I/O peripheral controller is a single-chip
solution offering complete I/O capabilities for PC/AT and PC/XT
environments. The 82C721 supports motherboard applications with
configuration via software.
The 82C721 features a floppy disk controller, a digital data
separator, two 16450 compatible UARTs, a bi-directional parallel port,
an IDE interface control logic and a game port chip select.
The floppy disk controller is software compatible with NEC uPD72065B
floppy disk controller. The controller supports up to four drives
directly. The digital data separator is capable of data transfer rates
up to 500kb/sec and requires no external components.
The 82C721 has two UARTs which are compatible with NS16450 UARTs. The
IDE control logic provides a complete IDE interface for embedded hard
disk drives. The bidirectional parallel port maintains complete
compatibility with ISA and PS/2 parallel ports. It can be configured
for either output mode or for bidirectional mode.
The configuration RAM and circuitry support programmable base
addresses for all the registers. Selection of sources of interrupts,
enabling and configuring of on-chip subsystems and the control of the
configuration process itself are also handled by this RAM and its
associated circuitry. The game port chip select provides a predefined
I/O address decode for games and joy stick applications.
The 82C721, designed for motherboard applications, is provided with
several power management features, which are controllable through
hardware or software. In hardware, the device can be completely
powered down through a power-down pin. In this mode, all inputs are
disabled, all outputs are inactive, and the contents of all registers
are preserved (as long as the power supply is maintained). In
software, the device allows each port to be powered down
independently.
The 82C721 features 24mA drivers for output buffers, including the
host data bus and the parallel port data bus. The floppy output
drivers are capable of sinking 48mA. The host interface is PC
compatible and can be connected directly to the ISA bus.
