We want use NXP MPC5777C MCU to extend Sync. SRAM externally.
https://www.nxp.com/files-static/32bit/doc/data_sheet/MPC5777C.pdf
But the NXP MPC5777C some pins are ADMUX bus.
Cloud you guide us how to implement the connection?
Thanks,
Mitchell

Hi Mitchell,
The connections are not feasible without any glue logic. You will need to implement address latch it in the design. You can also check this in the timing diagrams of the Sync part in the datasheet that there are some times overlap in the address and data contents and that will need a proper logic for reliable operation.
Thanks,
Pradipta.

Update below NXP timing diagram for reference.
Does Cypress CY8C1381KVE33-133AXI can direct connection without glue logic?
Or is need implement address latch IC in this design?
Thanks,
Mitchell
