I'm considering interfacing LY62L25616 256kx16 (please see the attachment ) external SRAM with 21479 in my custom board.
Does this part ok for 21479 ?
I think it might not be a problem to interface this SRAM (LY62L25616 256kx16) to ADSP-21479.
It is recommended to follow the circuit design used for interfacing ADSP-21479 and the SRAM part (IS61WV102416BLL) used in the ADSP-21479 EZ-Kit .The EZ-Kit schematics can be found in the link given below
Make suitable changes to the schematics to interface your SRAM part .The Wait states must be properly programmed depending on the Access time of the SRAM.
My question is the IS61WV102416BLL has A0-A19 address lines , the LY62L25616 only has A0-A17
is it ok to omit the A18 and A19 ?
Yes , you can omit the higher order address lines A18 and A19.
