External memory interfacing with TS201

Started by prakash b April 24, 2007
hi
Iam trying to interface TS201 with 16 bit external memory peripheral.
in TS201 Ezkit they explained for SDRAM and EPROM interfacing.
for EPROM they connected from A0-A18 address lines and D0-D7 data bus directly.
and for SDRAM they configured A1 through A31 of TS201 and D0-D31 and D32-D63 data bus connected to SDRAM.

so for 16bit data bus(D0-D15) and 12bit address(A0-A11) can I configure A0-A11 and D0-D15 of TS201 directly? or from A1-A12 and D0-D15 of TS201? which should I select in above?
TS201 EPROM SDRAM 16bit memory interface
A0-A31 A0-A18 A1-A31 ?---?--?
D0-D63 D0-D7 D0-D31 ?--?--?
D32-D63

Iam greatful to your advices.
