LPC2292/94 External Memory Interfacing

[contagiouseddie]

Hi Everyone,

It is possible to interface LPC2292/94 with SDRAM instead of SRAM?
In the user manual, it stated the external memory controller supports only SRAM.

Thanks.

hi

You can do it but SD RAM need spcial control signal who will consum lot of processing power from the LPC - so it is not recommanded

You can also use a CPLD as an interface between the LPC22xx and the SD ram but it cost

TRY the LPC24xx it support SDRAM


All the best

I thought using of LPC24xx too. But it's a bit hard to obtain here. So, I decided to go for some other ARM vendor as SRAM is seeing quite the end already.
Thanks.
