MAX II reprogramming cycles?

Hello guys. 

 

I am wondering what the "erase and reprogram cycles" of 100, that is stated for the Altera MAX II CPLD, physically mean. 

 

Does this mean I can only program a source code into the device for 100 times?  

Or don't I use the UFM and CFM blocks every time when I program a basic source code? 

 

If this is really the programming of every kind of code, the number of 100 really is an issue. 

I bought a dev. kit for this CPLD to help me understand VHDL and just play around with it, so 100 chances aren't that great...

you're right, you can only erase the MAXII's internal flash up to 100 times to still be in the operating specs. in a non-production environment you can probably push it out past 100 erases, but you may want to think about getting a small FPGA dev kit which is SRAM based. an FPGA won't have the same issue with erases as CPLD flash memory.

Bummer, that's really a con! 

The kit cost me about 70 pounds... :( 

 

What set with a FPGA (not with too much additional stuff like LCD etc.) would you advise?

if you want to go very low cost there is an eBay seller that has a kit with a Cyclone II 5 kLE device and an EPCS configuration device. i am not the seller nor have i tried the board, but its one of the cheapest way to get an Altera FPGA dev kit. you'd have to add any peripherals (LED, 7-seg, LCD, switches, etc).
