**GC101/102     12/16MHz PC/AT Compatible Chip Set             c:Feb88
***Info:
The GC101/GC102  is a fully  IBM PC/AT compatible chip  set supporting
the 80286  CPU at  clock Speeds  up to  16MHz. This  highly integrated
three chip solution features  high performance, low power consumption,
low board space requirements, high  reliability, and low cost. A fully
PC/AT compatible system maybe implemented with this chip set, the CPU,
Keyboard Controllers, RTC and 7  other devices plus memory.  This chip
set supports 256K and 1 Mbit DRAMs in configurations up to 4 megabytes
at zero or one wait state.  Zero wait state operations is supported up
to 12MHz and one wait at up to 16MHz.

The GC101 performs CPU and Peripheral support functions including that
of  DMA  Controllers, a  Memory  Mapper,  Timers, Counters,  Interrupt
Controllers, a  Bus Controller, and their  supporting circuitry.  This
device is packaged in a 160 pin flat pack.

The GC102 maybe configured as  either an Address Buffer or Data Buffer
by strapping one pin high or low.  This chip replaces address buffers,
data  transceivers, memory drivers,  parity generators  and supporting
circuitry. This device is packaged in an 84 pin PLCC

***Configurations:
GC101 CPU and Peripheral Controller
GC102 as Address Buffer
GC102 as Data Buffer

chips suffixed -12 are 12 MHz, -16 are 16 MHz.
