I am searching for a replacement part for EPM7064STI44-7, which has been discontinued. I have attached the data sheet below, and the part description is EE PLD, 7.5ns, 64-Cell, CMOS, PQFP44, or "PROGRAMMABLE LOGIC DEVICE." I have attached the related datasheet. Please let me know if there are any alternatives.
What are the requirements for your replacement part?
Is this for an existing design or a new design?
Same package and/or pinout?
Same I/O compatibility (ie, 5V CMOS)?
Something in the MAX family: https://www.intel.com/content/www/us/en/products/programmable/max-series.html
is probably your best bet for a close approximation. Doubt very much you will find any exact replacement (pinout/package).
