The 15 ns access time sets the bus timing window for a 16-bit host. ## Obsolete — sourcing through independent channels Infineon (formerly Cypress Semiconductor) has marked the CY7C1021BL-15ZXI as obsolete. No official successor part number is published in the lifecycle record. This part is no longer available through factory-authorized distribution and must be sourced through independent surplus and broker channels. No production-status claim is made beyond the obsolete listing.","metaTitle":"Infineon CY7C1021BL-15ZXI 1Mbit Async SRAM, 15 ns","metaDescription":"Infineon CY7C1021BL-15ZXI 1Mbit asynchronous SRAM, 64K x 16 organization, 15 ns access time, -40°C to 85°C, 44-TSOP II.
