I need to solve a high speed logic issue with a circuit I am designing. Currently I am solving it using a bunch of XOR and NAND gate IC's but they are taking up 30% of my board space and I am looking for a small package solution to replace them with so I can get some space back. I am thinking that an FPGA is a good solution but I am not finding small stuff just big chips with hundreds of IO pins that can run an entire cell phone.
Altera comes up a lot in my searching so I am hoping someone here may know what I am looking for. I just need something basic that will let me program my simple logic into an IC that I can solder on to my circuit board and I only need 32 IO but anything less then 100 would be good. I would like an SDK that costs less then $1000. I would like it more if it runs in Linux but that is not a deal breaker if the chip is small and the SDK is affordable.Link Copied

you should take a look at the MAXV CPLD family. they come in 64-pin QFP:

What is high-speed to you?
The older MAX II CPLDs work fine too. Altera jumped from MAX II to MAX V, so ignore the missing roman numerals in the part number sequence :) I've used the EPM570 for implementing power-control and FPGA configuration controller logic. They've got plenty of logic elements for what you want to do. The logic runs at 125MHz and the devices are close to full. A couple of comments though: Pros: The MAX CPLDs have on-board EEPROM, so they are sort-of instant turn-on devices. They have ~4MHz oscillators on them that you can use, though an external clock might be useful depending on your application. Cons: The MAX CPLDs do not have on-chip RAM, so you cannot use the Altera NIOS processor (though, this is not a con for your application). Either of the MAX CPLDs would work fine for you. Cheers, Dave![](/skins/images/0B743BCD37FD8EED134343C203D4D429/responsive_peak/images/icon_anonymous_message.png)
