Hi!

i want to connect a samsung k4s561632h-uc75 dram to a stm32f429zgt6.

some pin in stm32 and ram have different names... i confused to connect which one from stm32 to which one of ram!!

please check attachments!!

...

or its better to use another ram chip?

thanks.

the things that i know:

FMC_A0~FMC_A13 ----------> A0~A12

FMC_D0~FMC_D15 ----------> DQ0~DQ15

FMC_SDNWE ----------> WE

FMC_SDNRAS ---------->RAS

FMC_SDNCAS ---------->CAS

FMC_BA0 & FMC_BA1----------> BA0 & BA1

FMC_SDCLK ---------->CLK

the rest pin of stm32:

FMC_BL0, FMC_BL1, FMC_SDNE0 and FMC_SDKE0.

i guess FMC_SDNE0 and FMC_SDKE0 Should be connected to CS and CKE?

at last LDQM And UDQM? to FMC_BL0 and FMC_BL1?

FMC_SDCKE0 would go to CKE

FMC_BL0 LDQM (Lower Byte)

FMC_BL1 UDQM (Upper Byte)

FMC_SDNE0 or FMC_SDNE1 to CS depending if you want STM32 Bank 1 or 2, ie 0xC0000000 or 0xD0000000 ranges

>>or its better to use another ram chip?

If you want an easy translation, pick a part used in the EVAL or DISCO reference designs.
