**UM82C480     386/486 PC Chip Set                                 c91
***Info:
The UMC82C480  is a highly  integrated, IBM PC/AT compatible  chip set
for  high performance  80386/80486  based  personal computer  systems.
Built with  exquisite [yes  it really says  that] cache  controller in
advanced   1.0um   CMOS   technology,  UM82C481   (Integrated   Memory
Controller, IMC),  UM82C482 (Integrated System Controller,  ISC), with
UM82C206 (Integrated  Peripheral Controller, IPC), and  limited counts
of  commercial parts  constitute  a low  cost,  highly reliable,  full
advanced feature personal computer system.

The UM82C482,  Integrated System  Controller (ISC),  is part  of UMC's
high  performance 80386/80486  PC/AT  chip set.   It  contains AT  bus
control  logic, data  bus  conversion logic,  CPU  reset logic,  clock
generation  for  CPU,  keyboard   and  timer,  DMA/refresh  logic  and
peripheral  interface logic.   Incorporated with  UM82C481, integrated
Memory   Controller  (IMC),   and   UM82C206,  Integrated   Peripheral
Controller (IPC),  ISC provides  system control functions  for overall
PC/AT computer system.

The UM82C481,  Integrated Memory  Controller (IMC),  is part  of UMC's
high performance 80386/80486 PC/AT chip set. It contains sophisticated
direct-mapped  cache controller  with write  back operation,  and fast
page  mode DRAM  controller.  Incorporated  with UM82C482,  Integrated
System   Controller  (ISC),   and   UM82C206,  Integrated   Peripheral
Controller (IPC), IMC provides main memory management function for the
PC/AT computer system.
