maintain the states held before the device went into the standby mode. There is no speed
penalty associated with coming out of standby mode.
When any input switches, the internal circuitry is fully enabled, and power consumption returns
to normal. This feature results in considerable power savings for operation at low to medium
frequencies. This saving is illustrated in the I
vs. frequency graph.
CC
Product-Term Disable
On a programmed PALCE16V8Z, any product terms that are not used are disabled. Power is cut
off from the product terms so that they do not draw current. As shown in the I
vs. frequency
CC
graph, product-term disabling results in considerable power savings. This saving is greater at the
higher frequencies.
Further hints on minimizing power consumption can be found in a separate document entitled,
Minimizing Power Consumption with Zero-Power PLDs.
