NOTES:
(1) When in the 1-x input clock mode, CLKIN is an input to an internal phase-locked loop and must maintain a minimum
frequency of 8 MHz for proper processor operation. However, in the 1-x Mode, CLKIN may still be stopped when the
processor either is in a reset condition or is reset. If CLKIN is stopped, the specified RESET low time must be provided once
CLKIN restarts and has stabilized.
(2) Case temperatures are ‘‘Instant On’’.
4.3 Recommended Connections
Power and ground connections must be made to
multiple V
CC
and V
SS
(GND) pins. Every 80960CF-
based circuit board should include power (V
CC
) and
ground (V
SS
) planes for power distribution. Every
V
CC
pin must be connected to the power plane, and
every V
SS
pin must be connected to the ground
plane. Pins identified as ‘‘N.C.’’
must not
be con-
nected in the system.
Liberal decoupling capacitance should be placed
near the 80960CF. The processor can cause tran-
sient power surges when its numerous output buff-
ers transition, particularly when connected to large
capacitive loads.
Low inductance capacitors and interconnects are
recommended for best high frequency electrical per-
formance. Inductance can be reduced by shortening
board traces between the processor and decoupling
capacitors as much as possible. Capacitors specifi-
cally designed for PGA packages will offer the low-
est possible inductance.
For reliable operation, always connect unused in-
puts to an appropriate signal level. In particular, any
unused interrupt (XINT, NMI) or DMA (DREQ) input
should be connected to V
CC
through a pull-up resis-
tor, as should BTERM if not used. Pull-up resistors
should be in the range of 20 K
X
for each pin tied
high. If READY or HOLD are not used, the unused
input should be connected to ground.
N.C. pins
must always remain unconnected.
Refer to the
i960 CA Microprocessor Reference Manual for more
information.
