CPU Thermal Sensor
Layout Note:
Route H_THERMDA and
H_THERMDC on same
layer.
10 mil trace on 10 mil
spacing.
Note: No Stuff for
Normal Operation
Address Select Straps
Current Address:
1001 110x
Thermal Diode Conn
Note:
If using Thermal Diode
Conn, NO STUFF
C2A1 and U2A1.
Run separate H_TCK
trace to processor for
FBO and TCK pins on
ITP.
Place TCK
pulldown resistor
within 1" of ITP.
Place TMS
pullup resistor
within 1" of
ITP.
Place TDI pullup
resistor within
2" of ITP.
Place TDO
pullup resistor
within 2" of
ITP.
DBA# may be left
unconnected.
Place RESET# serial
resistor within 0.1"
and RESET pullup
resistor within 0.3".
The ITP should be at
the end of the
H_CPURST#
transmission line but
less than 6.0" from
the processor.
H_BPM[5:0]* signals
should be matched
to within 0.25" of
each other and not
longer than 6.0".
Place 0.1uF cap within
0.1" of VTT pins on ITP.
Place BPM pullups
near processor.
