EPCS16 Substitute

[RDama1]

I am using Cyclone III devices with EPCS16, with quartus 9.1(!!)

I want to know:

1. can I replace the IC into EPCQ16A?
2. What is the quartus version that support the new devuce?
3. can I get some samples for evaluation?

Thanks

Hi Rami Damari,

If you look at AN822 (Table 4 on page 9), the Intel Quartus software support EPCQ-A device starting from version 17.1 and later.

However, EPCQ-A device can be programmed with old JIC files created for EPCS/EPCQ device. Unfortunately, there are some conditions you need to follow in order to program with old JIC file. These are the conditions:

• If the target serial flash was an EPCS/EPCQ device of density <= 64Mb. 
• If the EPCS/EPCQ device was only used for FPGA configuration and the design did not have any instances of ASMI Parallel IP / Serial Flash Loader (SFL) IP or any other serial flash controller IPs. 
• If the designs target pre 28nm Intel® FPGAs, i.e. devices prior to Arria® V, Cyclone® V, or Stratix®V.

For your case, you are using Quartus 9.1 version and Cyclone III, EPCQ-A device would not support your FPGA and Quartus.
