The 44-TSOP II footprint is common across the CY7C1041 family, so board layout carries over if you swap density variants. ## What the 20 ns access time buys the bus The 20 ns access time means the SRAM can deliver data within 20 ns of the address being valid, which is fast enough to work with 5 V CPLDs, legacy ASICs, and older microcontrollers that run bus cycles in the 40–50 ns range. If your controller's read strobe is tighter than 25 ns, you will need to check setup-and-hold margins against the datasheet's AC timing table — the 20 ns figure is the ceiling, not the typical.","metaTitle":"Infineon CY7C1041BN-20ZSXAT 4Mbit Async SRAM, 20 ns","metaDescription":"Infineon CY7C1041BN-20ZSXAT 4Mbit asynchronous SRAM, 20 ns access time, 256K x 16, 44-TSOP II, -40°C to 85°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":"Tape & Reel (TR)","Technology":"SRAM - Asynchronous","Access Time":"20 ns","Memory Size":"4Mbit","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":"CY7C1041","Memory Organization":"256K x 16","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"44-TSOP II","Write Cycle Time - Word, Page":"20ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.8900","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1041BN-20ZSXAT/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy CY7C1041BN-20ZSXAT?","answer":"We source the CY7C1041BN-20ZSXAT through independent distribution and surplus inventory.
