The CY7C1049CV33-10VXAT: The part comes in a 36-SOJ surface-mount package, a common footprint for memory modules on parallel buses.
The parallel interface is straightforward to connect, but the tight timing means the layout engineer should keep trace lengths short and decoupling close to the supply pins to maintain signal integrity.
Yes, Cypress has classified the CY7C1049CV33-10VXAT as obsolete. There is no official replacement listed. For existing production, source through independent distribution against an RFQ.
All I/O pins are 3.3 V tolerant within that range.
The access time is 10 ns, and the write cycle time (word, page) is also 10 ns. This allows single-cycle reads and writes on a 100 MHz bus with no wait states.
