**CS4041/5 CHIPSet (84041/84045) 2/10/95
***Info:
The CS4041 is the first product in the GreenCHIPS CHIPSet product
portfolio of Chips and Technologies, Inc. It provides all of the
system logic for implementing a high performance, Energy Star
compliant 486 PC/AT design, while maintaining an extremely competitive
cost structure. The powerful feature set includes the CHIPS "standard"
system blocks and offers a new level of system integration while
addressing the ever evolving requirements that the market place
demands. It is 100% PC/AT compatible and directly supports the 486DX,
486DX2, 486DX4, 486SX and 486 derivatives that support the CPU write
back cache architecture.
The high performance CHIPSet consists of the F84041 Systems Controller
and F84045 GreenCHIPS IPC. The F84041 System Controller is packaged in
a 208-pin PQFP and integrates the major system logic
functions. Included in the F84041 is the CHIPS patented Page
Interleave DRAM controller, high performance cache controller, VL
local bus controller, ISA bus controller, power management module, a
local bus IDE controller and fully compatible 8042 keyboard controller
with PS/2 mouse support. The companion F84045 is packaged in a 100 pin
PQFP and contains the industry standard Integrated Peripheral
Controller (IPC) which includes the DMA controllers, timers, interrupt
controllers and real time clock.
The enhanced feature set of GreenCHIPS DRAM and cache controllers are
perfect for today's High Performance PC/AT designs. The page
interleave DRAM controller offers high performance as well as extreme
flexibility in supporting 486 memory subsystems. The DRAM controller
supports up to eight banks of memory that can be configured with 256K,
1M, 4M or 16M memory devices. Page interleaving, timing modes, memory
mix options, direct drive support and block by block parity support
can be tuned to meet the most optimum requirements for the system
design. In addition, the high performance secondary cache controller
provides options that can be optimized for performance, cost or
both. The direct mapped cache architecture employs internal
comparators with external TAG and data SRAM that can operate in a
write-through or write-back mode. Cache sizes from 64K to 1M are
supported with flexible single bank or dual bank support that allow
flexible timing mode selection based on CPU speed and SRAM speed.
The "Green" in GreenCHIPS comes from the Power management support
integrated in the CHIPSet. The CS4041 provides the perfect level of
power management support for Energy Star compliant desktops. Included
in the power management section is direct support for SMM operation
and clock switching for the popular 486 derivatives. Two event timers,
programmable I/O pins, I/O restart and programmable event detection
provide a wide range of options for power management selection and
customization.
The CS4041 provides new levels of integration in system logic CHIPSets
by providing a local bus IDE interface and keyboard controller. The
robust local bus IDE interface is decoupled from the AT state machine
and does not use a VL local bus load. The interface is versatile
enough to support up to eight IDE drives allowing each drive to have
unique command settings. The result is the best performance for each
drive type allowing significant performance gains over the standard
ISA interface. This is accomplished without any compromise to the
standard VL local bus.
