No ground pin in Max V 5M80ZE64I5N CPLD

We are planning to use Altera Max V 5M80ZE64I5N CPLD in oneof our designs. We need 54 user I/O’s in the design. As per the link https://www.altera.com/content/dam/altera-www/global/en_us/pdfs...

Hi Sinora,

Yea, you will need to connect the GND pad. Also you will have the 54 IOs... If it was mentioned in the pin out it should have. In the case you do not have 54 IOs... You might need to get back to Altera and check what is the reason for the inconsistency between the documentation and the actual product.

Some of the consideration to take in is the power, the IO standard, the inputs and outputs. Dedicated clk pins for the refclk input.
