The 64 K × 16 organization matches 16-bit MCUs and DSPs. Write cycle time matches read access at 12 ns. This part is obsolete per Cypress. Sourcing is through surplus and broker channels. ## 5 V supply — legacy system consideration The 44-SOJ package is a surface-mount, J-bend lead form — it reflows with standard profiles but the 0.400\" body width is wider than a typical SOIC, so check the board footprint clearance.","metaTitle":"Cypress CY7C1021BN-12VXC 1Mbit Async SRAM, 12 ns","metaDescription":"CY7C1021BN-12VXC from Cypress: 1Mbit asynchronous SRAM, 64K x 16, 12 ns access time, 4.5-5.5V, 44-SOJ, 0-70°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Mfr":"Infineon Technologies","Series":"-","Package":"Tube","Technology":"SRAM - Asynchronous","Access Time":"12 ns","Memory Size":"1Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"44-BSOJ (0.400\\\", 10.16mm Width)","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"4.5V ~ 5.5V","Base Product Number":"CY7C1021","Memory Organization":"64K x 16","Operating Temperature":"0°C~70°C(TA)","Supplier Device Package":"44-SOJ","Write Cycle Time - Word, Page":"12ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/87056a907f3868cf5838858aebd2682e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1021BN-12VXC/alternatives.json"},"ai":{"faq":[{"question":"Can I replace CY7C1021BN-12VXC with a faster SRAM?","answer":"A faster asynchronous SRAM (e.g., 8 ns or 10 ns) in the same 44-SOJ package and 64 K × 16 organization could be a functional replacement, provided it operates at 5 V and meets your timing requirements. However, no official replacement is listed by Cypress.
