dumb question CPLD or FPGA

Started by Joseph Goldburg April 17, 2004
What's the difference  between say the Xilinx Coolrunner CPLD
and the Xilinx 4000 FPGA series.

I noticed the coolrunner dev kit for $50 USD

Please reply to this new group and wizard1@netspace.net.au

Thanks in advance

The Coolrunner is a current product and the 4000 series devices are obsolete. 8-) Leon
Joseph,

The Coolrunner is a CPLD, and the 4000 was a FPGA:  totally different 
architectures.  Both are programmable logic devices, however.  In 
general, the largest CPLD is still much smaller than the smallest FPGA 
in the capacity to do something (gates, flops, etc).  CPLDs like 
Coolrunner have extremely low quiescent current and get used in 
handheld, or portabke devices often (like cellphones), whereas the FPGA 
has a larger quiescent current and is not usually found in a battery 
operated device, but rather its large number of gates are used in places 
like cellular base-stations.
