**UM82C380     386 HEAT PC/AT Chip Set                             <91
***Info:
The UMC's HEAT (High End AT) Chip Set UM82C380 is a highly integrated,
flexible solution for high performance 80386 PC/AT compatible systems.
Fabricated using  advanced 1 .2u.   CMOS VLSI technology,  it provides
high  reliability,  low power,  low  chip  count  features for  system
implementation. A  commercial 25MHz/0 wait state.  12MByte main memory
system with cache memory  control and math-coprocessor features can be
easily built in a standard baby AT size mother board (12" x 8.6") with
all necessary components included.

The  UM82C380  series consists  of  five  chips,  the UM82C381  System
Controller,  UM82C382 Address Buffer,  UM82C383 Data  Buffer, UM82C384
Memory  Controller  and UM82C388/389  Cache  Interface. Combined  with
UMC's UM82C206 Integrated Peripheral  Controller, the chip set forms a
highly  integrated  solution  for   25MHz  80386  PC/AT  systems  with
Page/Cache Mode options.

The  UM82C380 series  supports a  local  32-bit CPU/MP  bus, a  32-bit
memory  data bus,  a  16-bit AT  channel  bus, an  8  bit I/O  channel
peripheral  data  bus  and  8MHz  system clock  to  provide  the  best
compatibility with industry standards.

The UM82C381 is a System  Controller. It provides all four bus control
signals, synchronized reset for  CPU and peripherals, refresh control,
math-coprocessor  (80287/80387)  interface,  address  decoding  logic,
CLK2, BCLK and timer clock generation.

The UM82C382  is an Address  Buffer. It provides address  interface to
processor  address, system  address,  DMA address  XA  and latched  XD
bus. A  10-bit refresh counter is  included for both 256K  and 1M DRAM
refresh.

The UM82C383 is a Data Buffer. It provides bus interface for CPU local
data bus, system data bus  and peripheral data bus. Word-swap logic is
also  built in  to  facilitate the  80386  read or  write 32-bit  data
through PC/AT 16-bit data bus.

The UM82C384  is a Memory  Controller. It provides control  for 32-bit
memory data bus,  memory paging control for 256K and  1M DRAM, RAS and
CAS control for system memory.

The  UM82C388  is  a  Cache  interface.  It  provides  a  simple  DRAM
controller to  interface INTEL 82385 Cache controller  with the system
memory.

The UM82C389  is another  Cache Interface. It  also provides  a simple
DRAM Controller to interface  UM82152 Cache Controller with the System
Memory, it has been highly integrated for easy application.

Basically, three  different 80386  PC/AT system configurations  can be
implemented using UM82C380 series HEAT  chip set. These are Page Mode,
UM82152 Cache  Control Mode, and  INTEL 82385 Cache Control  Mode. All
three  mode implementations will  require the  four common  core logic
devices  of   HEAT  chip  set;  UM82C381  ,   UM82C382,  UM82C383  and
UM82C206. The UM82C384  will be needed for Page  Mode , while UM82C389
and UM82C388 are needed for UM82152 and 82385 Cache Control Modes. The
block diagrams and the required  IC list for each system configuration
is illustrated in Figures 1 ,2, and 3 [see datasheet].

A software driver is required  to initiate the UM82152 when the system
is working in UM82152 Cache Control  Mode. A PAL equation is needed to
implement  the HEAT  chip set  working  in INTEL  82385 Cache  Control
Mode.  Either or  both  of these  tools  can be  requested from  UMC's
worldwide sales offices.
