***Features:
General Features:
o Supports 3.3V and 5V Intel, AMD & Cyrix SMI 486 CPUs and the "NEW"
Intel Low Power 486 CPUs
o True single chip notebook implementation (internal '206) based on
the proven 82C461/462 core.
o Single 208-pin PQFP package implemented in 0.8u CMOS technology
o 100% IBM AT compatible solution
o Supports operation up to 33Mhz at 5V and 25Mhz at 3.3V
o Fully supports local bus implementations, including VESA VL-bus
o Supports Sequencer microcode, System BIOS and Video BIOS combined
in a single 8-bit ROM
o Option for Write protected, cacheable video and system BIOS
o Emulation of fast CPU reset and gate A20, as well as port 92h
support
o Standard system requires only six TTL plus a Real Time Clock (RTC)
o Test mode support for in-circuit testing
o Two programmable chip selects and exter software utility timer
DRAM Controller Features:
o Page-mode DRAM controller supports 2-1-1-1, 3-1-1-1, 3-2-2-2 and
4-3-3-3 burst read memory cycles.
o DRAM controller supports zero wait state DRAM write cycles
o Supports for banks of 256K, 512K, 1M and 4M DRAMs for
configurations up to 64MB
o Support for two programmable non-cacheable regions
o Fully programmable shadow RAM in C0000h-FFFFFh
o Slow refresh, CAS before RAS refresh and self-refresh support.
Power Management Features:
o Supports SMI features for Intel, AMD & Cyrix SMI CPUs and the
"NEW" Intel Low Power 486 CPUs
o Sequencer power management, with enhanced features over the
82C461/462 Sequencer
o Full Microsoft APM support, with CPU stop-clock support
o Support for CPU clock stretch function
o Supports system-level zero-volt suspend
o Flexible power saving modes with support for individual peripheral
time-outs
o Operating system & application independent power management (no
device drivers needed)
o 16 PMI event sources to generate SMI or to activate Sequencer
o Supports I/O trap for peripheral device power control
o Eight peripheral power control pins plus four user definable
I/O pins
o RTC alarm or modem ring auto wake-up
o Suspend current leakage control
o Static AT-bus clock when AT-bus is idle.
