If the bus runs at 66 MHz (15 ns cycle), you are down to 5 ns margin, which demands careful PCB trace length matching and may need a faster SRAM. Infineon lists the CY7C1021CV33-10ZSXA with a Last Buy lifecycle status. That means the manufacturer has announced a final ordering window — once that closes, the part will no longer be produced. For a production BOM, this triggers a last-time buy decision or a qualification of a replacement. If you have an active design using this SRAM, now is the time to secure lifetime buy quantities or identify a pin-compatible alternative. ## Package and footprint — 44-TSOP II The 44-TSOP II package (0.400-inch body width, 10.16 mm) is a standard SRAM footprint used across multiple vendors. The 44-TSOP II is the same footprint used by many 1 Mbit and 4 Mbit asynchronous SRAMs, which simplifies a potential swap.","metaTitle":"Infineon CY7C1021CV33-10ZSXA SRAM, 1Mbit, 10 ns, 44-TSOP II","metaDescription":"Infineon CY7C1021CV33-10ZSXA asynchronous SRAM, 1Mbit (64K x 16), 10 ns access time, 3V-3.6V supply, -40°C to 85°C, 44-TSOP II.
