The device is housed in a 44-pin SOJ (Small Outline J-lead) package, a surface-mount footprint common in memory subsystems for embedded controllers, telecom line cards, and industrial automation boards where a 16-bit data bus is required. For a processor running a 50 MHz bus (20 ns cycle), this leaves a 5 ns margin after accounting for address-to-chip-select setup and output hold — workable but tight. Designs that need back-to-back reads without wait states should verify the timing closure against the host's memory controller spec. ## Obsolete — sourcing through independent distribution Infineon lists the CY7C1021B-15VXIT as obsolete. For BOM lines that require this exact order code, the only channel is surplus or broker inventory.","metaTitle":"Infineon CY7C1021B-15VXIT 1Mbit Async SRAM, 15 ns, 44-SOJ","metaDescription":"CY7C1021B-15VXIT from Infineon is a 1Mbit (64K x 16) asynchronous SRAM with 15 ns access time, 4.5V-5.5V supply, industrial temp range.
