256MB x16 bit IFC nor flash interface with T2080

Hi,

I am using T2080 in my application in this I planned to connect S70GL02GS12FHIV20 nor flash to the IFC bus. I planned to use x16 bit external latch for address/date demux application. How to interface this devices, My flash is having 27bit addressing.

Regards,

Rajesh

Connections should be as shown in RM Figures 13-277, 13-326

ADM MODE 0, CSOR0[ADM_SHFT]=4

[IFC_AD[0:15],IFC_AVD] -> latch -> A[26:11]

IFC_A[20:30] -> A[10:0]

IFC_AD[0:15] <-> DQ[15:0]

IFC_CS0# -> CE#

IFC_OE# -> OE#

IFC_WE0# -> WE#

IFC_WP0# -> WP#

IFC_RB0# -> R/B#

1.8V -> VIO

3.3V -> VCC

PORESET# -> RESET#

Have a great day,
Pavel

Hi Pavel,

Should it be "IFC_A[16:26] -> A[10:0]" instead of "IFC_A[20:30] -> A[10:0]" ?

BR,

Denis

Hi,

Thanks for the recommendation, As per your recommendation I need to provide latch for 16bits(AD0 to AD15) instead I have connected like this whether this will work ?

IFC_A[16:30] -> A[14:0]

[IFC_AD[4:15] -> latch -> A[26:15]
