Decoupling Capacitors
Decoupling capacitors placed across the processor between V
supplying the extra current needed during switching. Place these capacitors close to the device
because connection line inductance negates their effect. Also, for this reason, the capacitors should
be low inductance. Chip capacitors (surface mount) exhibit lower inductance.

I/O Pin Characteristics
The i960 Jx processor interfaces to its system through its pins. This section describes the general
characteristics of the input and output pins.
