**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
