Re: MAXII to MAX5 CPLD foot print compatability
Dear Frank Thank you for your valuable reply. 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 you3.1KViews0likes0CommentsRe: 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?

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.

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 M3.4KViews0likes0CommentsMAXII 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?
