COOLING REQUIREMENTS
The M68360QUADS-040 is specified, designed, and tested to operate reliably with an ambient air
temperature range from 0
C to 30
C. This, due to the overheating problems of the XC68EC040 as the
68EC040
must
have a heat-sink attached to it for proper operation at room

temperature. Therefore, the
should never exceed 30
O
C
.
a. The 12V supply is not used on the board, it is connected only to the Ethernet AUI connectors P3 & P5 to be supplied
to the network. Therefore, the power consumption of that supply is independent of the M68360QUADS-040.
b. 33 MHz components are used to get better s.u. timing between the QUICC & the EC040.
c. Since A28 to A31 of the slave QUICC are used as Write-Enable signals, the on-board addressing space is reduced
to 256 MBytes.
1. If no heat sink is attached to the 68EC040, maximum ambient temperature allowed @ 25 Mhz is -4
