Figure 36. M80C286 System Configuration with Dual-Ported Memory
Figure 36 shows the addition of dual ported dynamic
memory between the MULTIBUS system bus and
the M80C286 local bus. The dual port interface is
provided by the 8207 Dual Port DRAM Controller.
The 8207 runs synchronously with the CPU to maxi-
mize throughput for local memory references. It also
arbitrates between requests from the local and sys-
tem buses and performs functions such as refresh,
initialization of RAM, and read/modify/write cycles.
The 8207 combined with the 8206 Error Checking
and Correction memory controller provide for single
bit error correction. The dual-ported memory can be
combined with a standard MULTIBUS system bus
interface to maximize performance and protection in
multiprocessor system configurations.
Mechanical Data
The M80C286 pinout for both the Ceramic Quad
Flatpack, CQFP, and Pin Grid Array, PGA, packages
are shown in Figure 37. V
CC
and GND connections
must be made to mutiple V
CC
and V
SS
(GND) pins.
Each V
CC
and V
SS
MUST be connected to the ap-
propriate voltage level. The circuit board should in-
clude V
CC
and GND planes for power distribution
and all V
CC
pins must be connected to the appropri-
ate plane.
Table 17 shows the pin assignments for both the
CQFP and PGA components.
NOTE:
Pins identified as ‘‘N.C.’’ should remain completely
unconnected.
