dumb question CPLD or FPGA

[Joseph Goldburg]

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.

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.
