Hi all,

Are there CPLD without internal Flash (like FPGA, which usually don't have internal Flash)?

Thank you
 

What's the purpose? Why not just use an fpga?
 

It's not that CPLDs "have" internal flash from which they load - it's the nature of their construction that makes them non-volatile. Just like an EEPROM.

CPLD is describing a range of complexity and not referring to a specific technology. Altera e.g. designates devices with flash based FPGA technlogy like MAX II, MAX V and MAX 10 as "CPLD".

10 years ago, a MAX 10 would have been considered a quite powerful FPGA.
 

Ehm.. Altera does call their MAX 10 devices FPGA's. :wink:

But there isn't a sharp line between CPLD's and FPGA's. If there ever was it's increasingly blurred these days. Like FvM said, the distinction mostly refers to a range of complexity. And to some degree, architecture.
 

They are FPGAs, but nevertheless advertised as CPLD...
