The CY7C1363B-100AC: It is listed as obsolete, meaning Cypress no longer manufactures this part.
The 8.5 ns access time at 100 MHz clock defines the read-to-data-valid window.
The 18-bit word width maps directly to 18-bit data buses common in older network processors and FIFO buffers.
The 100-LQFP variant shares the same 14x20 mm body.
Yes, the CY7C1363B-100AC is listed as obsolete. Cypress no longer manufactures this part. Buyers should plan for surplus or broker sourcing.
