The CY7C1440AV33-250AXC: This is a pipelined, single-data-rate (SDR) part — each rising clock edge can initiate a read or write, but the data bus returns one word per cycle, not two. The 100-TQFP (14x20 mm) package uses a standard 0.5 mm pitch — the footprint is common across the Cypress 36 Mbit synchronous family, which matters if you are qualifying a drop-in replacement. That covers office equipment, telecom indoor racks, and benchtop instrumentation, but not an engine bay, outdoor base station, or factory floor without active cooling or a qualification waiver.
Cypress lists the CY7C1440AV33-250AXC as obsolete. If you are qualifying a replacement, the 100-TQFP (14x20) footprint and 3.3 V supply are the fixed constraints; any pin-compatible 36 Mbit synchronous SRAM from the same family would need to match the 250 MHz clock and 2.6 ns access time to avoid retiming the board.
