**WD8110 System controller for 80386DX/486 <11/30/93
***Notes:...
***Info:...
***Configurations:...
***Features:
o Interfaces with 80486SX, 80486SXLP, 80486DX, 80386SX and 80386DX
CPU's
o Operates at up to 33 MHz at 3.3 volts or 5 volts with the
80486SX/DX
o Operates at up to 33 MHz with the 80386SX/DX
o Supports single and double clock 80486SX/DX and Intel SL Enhanced
processors.
DRAM control:
o Page Mode word interleaved, DRAM controller with support for 80486
burst mode.
o Supports 3-2-2-2 clock sequence, 9 CLKs with 16-byte line fill for
a page hit DRAM read cycle at 33 MHz.
o Optional 3-1-1-1 clock sequence, 6 CLKs with 16-byte line fill for
static column mode DRAMs at CPU speeds of 16 MHz and 20 MHz
o Zero Wait State writes at 16 MHz and 20 MHz to DRAMS for
80486SX/DX
o One Wait State writes to DRAMs for 80386SX/DX
o One Wait State reads from DRAMs for Page Hit access for 80386SX/DX
o Supports memory in five DRAM banks for a maximum of 256 Mbytes,
using 256Kbit, 1 Mbit, 4 Mbit and 16 Mbit DRAMs and special DRAMs
such as 512K by 9, 1M by 18 and 2M by 9.
o Supports major DRAM standards, including Asymmetrical DRAMs Static
Column DRAMs and 88-pin DRAM cards.
o Self-adjusting output drivers minimize output rise/fall time
variations and reduce EMI and ground noise.
o DRAM address multiplexer capable of driving 450 pF with adjustable
strength drivers.
o Features CAS before RAS refresh and slow refresh for low power.
o Supports slow refresh and self refresh DRAMs at 120 us.
o I/O mapping for board testability
o 32-bit direct interface with internal parity generation and
checking with no DRAM data buffers required.
Power Management:
o Low power 0.9 micron CMOS technology
o Provides power control with suspend and resume mode operations.
o 3 volt suspend to hard disk and Hibernation.
o Sleep Mode provides:
- Stop clock for static CPU for power saving.
- Processor power down.
o Provides automatic processor clock switching for 80386.
o Automatic CPU speedup (AutoFast).
- Clock Scaling
- Clock Throttling
o Supports multiple CPU speeds.
o Supports System Management Interrupt (SMI) for efficient power
management.
o Provides peripheral and I/O power control with trapping on I/O
address ranges for SMI operations.
o Supports a fully programmable 16-bit decode.
o Provides System Activity Monitor (SAM) for power management.
o Stop DMA clock.
o 3.3V low voltage operation with on-chip translators for 5 volt AT
bus
(split rail operation).
o 3 volt and 5 volt mixed mode.
Chip Set Features:
o High speed DMA.
o Three fully programmable chip selects with PMC timers.
o Built in Immunizer for virus protection.
o Connects directly to the AT Data Bus SD(15:00).
o Supports a Video Local Bus Interface (VLBI) for a 32-bit Video
Graphic Array (VGA) interface.
o Bank switched BIOS ROM up to 512 KB.
