您好，

我想使用SEMC连接FPGA，都需要哪些引脚呢，FPGA是需要模拟为SRAM么？

Please look at the following community post where my colleague shares some useful resources about the connection of the RT with and FPGA. I believe you will find them useful: https://community.nxp.com/t5/i-MX-RT/MIMXRT1051-SEMC-connect-FPGA/m-p/1385947

Do let me know if you have further inquiries about this topic.

BR,

您好，
不好意思，我还是不太清楚：
1、如果数据线和地址线都使用的话，是只有FPGA当做SDRAM这种方式吧，那这种方式，有很多其他的引脚，这个是需要的么
2、如果FPGA当做SRAM，那么其中的CE#与CRE信号是怎么使用呢

Hi @ma123456,

1. Yes, the FPGA would have to be an SRAM-like device.

2. In order to provide a better answer for you, could you please specify what is the part number that you are currently using?

BR,
Edwin.

1、大多数是将FPGA当做SRAM还是SDRAM呢，因为这两种使用的线数是不一样的，有哪些是必须的呢
2、芯片为RT1052

Hi @ma123456,

The connection to the FPGA would be according to the "SRAM (ADMUX 16bit)" of the Table 25-6. SEMC Pin Mux Overview from the Reference Manual. In the case of unused signals like CE# and CRE, they can remain unconnected.

BR,
Edwin.

有相关的参考例程么
