The 12 ns write cycle time (word, page) matches the read access, so back-to-back transactions run at full bus speed with no dead cycles. Infineon (formerly Cypress Semiconductor) has marked the CY7C1021B-12VXIT as obsolete. The part is no longer manufactured and is not available through authorized distribution. For a BOM freeze or long-term production run, a pin-compatible second source in the same 44-SOJ footprint and 5V asynchronous SRAM family should be evaluated. No official cross-reference is listed here; qualification of any alternate requires electrical and timing validation against the 12 ns access time and 64K x 16 organization.","metaTitle":"Infineon CY7C1021B-12VXIT 1Mbit Async SRAM, 12 ns, 44-SOJ","metaDescription":"Infineon CY7C1021B-12VXIT 1Mbit (64K x 16) asynchronous SRAM, 12 ns access time, 4.5V–5.5V, -40°C to 85°C, 44-SOJ.
