Any remaining stock is finite; a last-time-buy window has already closed, so the buyer should qualify the BOM against a current-production alternative or secure a bridge lot through the broker channel. ## 64K x 16 organization and 15 ns timing The 64K x 16 memory organization gives a 16-bit data bus in a single chip, which simplifies the memory interface for a 16-bit microcontroller or a 32-bit CPU running in 16-bit mode.","metaTitle":"Cypress CY7C1021BNV33L-15ZXIT 1Mbit Async SRAM, 15 ns","metaDescription":"Cypress CY7C1021BNV33L-15ZXIT asynchronous SRAM, 1Mbit (64K x 16), 15 ns access time, 3V–3.6V 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":"15 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":"3V ~ 3.6V","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":"15ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.0700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b52313df5d733a20a081352c1eb65721.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1021BNV33L-15ZXIT/alternatives.json"},"ai":{"faq":[{"question":"Is CY7C1021BNV33L-15ZXIT obsolete?","answer":"Yes, the CY7C1021BNV33L-15ZXIT carries an Obsolete lifecycle status.
