Low Power Consumption

Industry's Lowest Power 1.8V CPLD

The CoolRunner™-II architecture, with its all-digital core, requires far less power than the older CPLD technologies that use power-hungry analog sense amplifiers -- with our FZP process technology, there is almost no standby current. Plus, it can be furthered scaled down with DataGATE so you can achieve even lower power results! CoolRunner-II is clearly the right CPLD solution for today's system power budgets.

Ultra low power of 28.8 µW

Ultimate Low Power with DataGATE

DataGATE permits input signal blocking, stops input switching, and reduces power. DataGATE can even block any input pins you select. Low power design can be attained without using DataGATE, but even greater results are possible for your entire design using it. In all, DataGATE enables CoolRunner-II to be a small fraction of the system power consumption -- no other CPLD can do this!

Benefits at a Glance

Power management (duty cycle, clock input and input pin)
Block input pins during insertion with hot plugging
Block sections of logic and snapshot signals with latches through debugging
Improve security by blocking access for various on stored code inside the device

CoolRunner-II Reduces Overall Board Power

CoolRunner-II CPLDs continue to employ the features of FZP technology to further advanced CoolRunner-II CPLDs as the low power standard. Other CPLD manufacturers have attempted to reproduce the FZP technology of the CoolRunner CPLDs, but have not been able to meet the CoolRunner benchmark. For the first time in the CPLD industry, CoolRunner- II devices deliver both true high performance and low power at the same time, along with the lowest standby current in the industry without the use of power down modes.
