The parallel interface eliminates the need for a memory controller, simplifying the glue logic on a legacy 5 V backplane.
The 64K x 16 organization maps directly to a 16-bit data bus, saving the byte-lane muxing that an 8-bit-wide memory would require.
No last-time-buy window is available from the manufacturer.
Yes, Infineon lists the CY7C1021BNL-15ZXIT as obsolete. There is no official replacement part from Infineon, so for existing production you will need to source it through independent distribution or qualify a pin-compatible alternative in the same 44-TSOP II footprint.
