PROMs XC18V00 - What kind of decouping capacitors should be used with this device?

Description

What kind of decoupling capacitors should I use with the 1800 device?

Solution

Use 0.01 to 0.1 microF capacitors close to the power/ground leads of the device. 

 

Use a larger capacitor close to where the power enters the board. 

 

FPGAs recommend a capacitor for each power/ground pair which is excessive for PROMs as PROMs do not have many I/Os, nor do they switch very quickly.
