We are giving only I/O banks power and not providing core power. What is the state of I/Os in this case? Is It ok to keep MAX V CPLD in this state? We are suspecting some assembly issue of this device and want to keep this device out of picture. Thank you Re: MAXII to MAX5 CPLD foot print compatability Dear Frank We want to Keep MAX-V CPLD without giving Core power and one Bank I/O power(Bank 3 1V8) (As we are not using this). But due to our design limitation we are giving power to other 3 I/O banks. Is it ok? Some of the I/os(Not powered) are connected to the Processor . In this condition our power circuit is beahaving weirdly. Is it ok to keep CPLD in this condition or better to remove this IC from the board? With Regards Krishnam Raju M Re: MAXII to MAX5 CPLD foot print compatability Dear Frank Thank you Re: MAXII to MAX5 CPLD foot print compatability Dear Naim Please help us on below poits, 1. Before programming the CPLD MAX V, What are the default states of all I/Os. Initiall after power up all I/Os(Before programming the CPLD) are driving some logic to processor beacuse of which I am facing some issue. 2. I want to keep all un used pins as input with high impoedence after programming the CPLD. How to make this setting in Quartus tool. With Regards Krishnam Raju M Re: MAXII to MAX5 CPLD foot print compatability Dear Naim Thank you. 1. I had already mounted MAX-V in place of MAX-II. 2. I found only T6 as the difference which was used as GPIO in my design. This GPIO is not crucial for my design. Can I gohead with testing? Will it create any problem? With Regards Krishnam Raju M Re: MAXII to MAX5 CPLD foot print compatability Dear Naim I found a T6 pin which is ground in MAX V is I/O in MAX II. Can you please look at this and the reason for this difference. With Regards Krishnam Raju M MAXII to MAX5 CPLD foot print compatability Dear Team We are chaning MAX CPLD II EPM2210F256C5N with MAX V CPLD 5M2210ZF256I5N . 1. Are both CLPDs foot print compatiable? 2. In my old design for MAXII VCCINT 3.3V is there and Now I am changing it to 1.8V as MAXV requires. Same symbol and foot print of CPLD II is used. Is it ok?
