**82230/82231 High Integration AT-Compatible Chip Set(ZyMOS) c:Aug88
***Notes:...
***Info:
The 82230 and 82231 are a two-chip implementation of LSI/MSI/SSI logic
controlling the IBM Personal Computer AT. The devices provide a low
power, highly integrated PC-AT design solution that may be applied to
any 80286-based system. With the 82230 and 82231, a PC-AT system can
be designed to operate at 12 MHz with zero wait state RAM accesses.
These standard cell products contain most of the logic peripherals to
the microprocessor and memory on the "standard" AT motherboard. The
LSI peripherals which support the AT design reside as supercells on
the 82230/82231 chips. these peripherals are compatible with the
products they replace and the user should refer to the standard
product data sheets for additional information on the operation of
these devices.
the PC-AT schematics in the IBM PC-AT Technical Reference Manual are
also a good source of information about the 82230/82231's internal
logic.
The 83320 performs the functions of the 82284 Clock Generator & Ready
Interface, 82288 Bus Controller for 80286 processors, 6818 Real Time
Clock/RAM, and the Master-Slave implementation of the dual 8259A
Programmable Interrupt Controllers as well as Command Delay, Shut
Down, Address/Data Bus Control and Ready Generation logic.
The 82231 includes the 8254 Programmable Interval Timer, 8284A Clock
Generator, LS612 Memory Mapper and the dual 8237 DMA Controller
functions as well as Refresh Generation and Refresh/DMA Arbitration
Logic.
