Infineon lists the CY7C1021D-10ZSXAT as Obsolete. We source this part through our independent supply network against your BOM quantity. ## 44-TSOP II footprint and supply rails The 44-TSOP II package (0.400-inch body width, 10.16 mm) is a standard SRAM footprint used across Cypress/Infineon and ISSI families — verify the pin 1 orientation against your existing layout before committing. The 4.5V–5.5V supply range is compatible with legacy 5V TTL buses; no level translation is needed when interfacing to 5V-tolerant CPLDs or ASICs.","metaTitle":"CY7C1021D-10ZSXAT Infineon 1Mbit Async SRAM 10 ns 44-TSOP II","metaDescription":"CY7C1021D-10ZSXAT from Infineon Technologies – 1Mbit asynchronous SRAM, 10 ns access time, 4.5V–5.5V supply, -40°C to 85°C, 44-TSOP II.","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":"Tape & Reel (TR)","Technology":"SRAM - Asynchronous","Access Time":"10 ns","Memory Size":"1Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"44-TSOP (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":"-40°C ~ 85°C (TA)","Supplier Device Package":"44-TSOP II","Write Cycle Time - Word, Page":"10ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.4800","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1021D-10ZSXAT/alternatives.json"},"ai":{"faq":[{"question":"How can I order CY7C1021D-10ZSXAT or check availability?","answer":"Submit an RFQ with your target quantity and lead-time window.
