**82340DX Chip Set (VLSI) (82346/82345/82355) 01/08/90
***Notes:...
***Info:...
***Configurations:...
***Features:
o Three Chip ISA (Industry Standard Architecture) Chip Set Capable
of Use in 386 DX-Based Systems Up to 33 MHz
- 82346 System Controller
- 82344 ISA Bus Controller
- 82345 Data Buffer
o Two 128-Pin and One 160-pin (82344) Quad Flatpacks 1.0- and 1.5-
Micron CMOS
o Memory Control of One to Four Banks of 32-Bit DRAM Using 256K,
1M, or 4M Components Allowing 64 Mbytes on System Board
o Page Mode DRAM Operation on Any Number of Banks
o Two/Four-way Interleaving or Direct Access on System Board
Memory
o Programmable Option for Block or Word Interleave
o Programmable DRAM Timing Parameters
o Remap Option Allows Logical Reordering of System Board DRAM
o System Board Refresh Optionally Decoupled from Slot Bus
Refresh
o Staggered Refresh Minimizes Power Supply Load Variations
o Built-in "Sleep" Mode Features Including Use of Slow Refresh
DRAMs in Power Critical Operations
o EMS Hardware Supports Full LIM EMS 4.0 Spec over Entire 64 Mbyte
o DMA Expanded to Allow Transfer over 64M range
o Support for 387DX Numerical Coprocessors
o Coprocessor Software Reset can be Disabled
o Internal Switching and Programmable CLK2 Support for Slow and
"Turbo" Modes
o Programmable Drive Reduces the Need for External Buffering on DRAM
and Slot Bus Interface Signals Allows
o ISA Bus Control of 386 DX-Based PC/AT-Compatibles. Capable of
Asynchronous or Synchronous Bus Operation to 16 MHz
o Compatible with Lotus 1-2-3 Version 3.0 in 1M Systems
o Bus "Quiet" Mode Assures that Slot Bus Signal Lines are Driven Only
During Slot Accesses
o Integrated Peripheral Functions:
- Two 82C37A DMA Controllers with Extended 74LS612 Page Register
- Two 82C59A Interrupt Controllers
- One 82C54 Timer
- One 148618 Real Time Clock
o Additional 64 Bytes of Battery Backed RAM in RTC Provides for Non-
Volatile Storage of 82340DX Chip Set Configuration Data and User
Specific Information
o Supports 8- or 16-Bit Wide BIOS ROMs
o Cache Support for Posted Writes
o System Memory on MD or D Bus in Non-Cached Systems
o Separate Parity Generators/Checkers for High Speed Operation
o Internal I/O Programmable for 10- or 16-Bit Decode
o Three-State Control Pins Added for Board Level Testability
