Can we use 5M40ZE64 instead of 5M80ZE64

I am making a design with 10M08DAF484C8GES FPGA, and in the schematic file I see there is a CPLD 5M80ZE64. But it is out of stock. So instead shall I use 5M40ZE64. My use cases are: (i) Loading th...

Looking at the board schematic the MAX V device is part of an embedded USB Blaster design on a development board designed by BeMicro.

So that begs the question, if you are going to use an external USB Blaster, why do you need the circuitry for the embedded USB Blaster design (ie, the miniUSB, the FT240XQ USB interface, and the MAX V as a protocol engine) at all?

Why would you not eliminate all that logic and just use the existing 10pin JTAG header J7 that is wired directly to the MAX10 FPGA?

I don't believe you need a MAX V device and the other mentioned circuitry at all based on your earlier statement.
