At 12 ns, it can keep up with a 33 MHz bus without wait states, assuming the controller's output-hold and setup windows are budgeted for a standard parallel SRAM interface. Any buy should be qualified against the original Cypress datasheet for date-code consistency and traceability. ## 44-TSOP II footprint and handling The supplier device package is 44-TSOP II, and the listed shipping medium is Tray.","metaTitle":"CY7C1021BN-12ZXC Infineon 1Mbit Async SRAM, 12 ns, 44-TSOP","metaDescription":"Infineon CY7C1021BN-12ZXC 1Mbit (64K x 16) asynchronous SRAM, 12 ns access time, 4.5V-5.5V supply, 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":"Tray","Technology":"SRAM - Asynchronous","Access Time":"12 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":"0°C ~ 70°C (TA)","Supplier Device Package":"44-TSOP II","Write Cycle Time - Word, Page":"12ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.3900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b005a36e8e3c18743572ba4643b8046f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1021BN-12ZXC/alternatives.json"},"ai":{"faq":[{"question":"Can CY7C1021BN-12ZXC be replaced by a 3.3V SRAM?","answer":"Not as a direct drop-in.
