Hi,

I want to use the LPC4337 with EMC+32 bit asynchronous SRAM but I can't figure out what the maximum frequency of the SRAM has to be for full performance. The LPC runs with 204 MHz. Do I need a SRAM that with the same frequency or what is the optimum frequency/access time of the SRAM?

In special, ISSI produces many SRAMs with a speed of 8 ns. Since 1/(204MHz) = 4.9 ns this value of 8 ns seems to be too big - or is the SRAM frequency for the LPC somewhere below?

Thanks!
