Its 12 ns access time and matching 12 ns write cycle let it keep pace with moderate-speed microcontrollers and FPGAs without inserting wait states — useful for cache buffers, scratchpad memory, or data acquisition staging in industrial control and telecom equipment. ## Supply and temperature — industrial range, 3.3 V rail The 44-TSOP II package (0.400\" body width, 10.16 mm) is a common footprint for mid-density asynchronous SRAMs, so PCB layout reuse across second-source candidates is straightforward. ## Obsolete — no official successor listed Infineon lists the CY7C1059DV33-12ZSXQ as Obsolete. No direct replacement order code is published in the lifecycle record, so buyers looking to fill a BOM line will need to source from independent distribution or qualified surplus stock. ## Sourcing reality for a discontinued SRAM Because this is an Obsolete part with no declared successor, new-design use is not recommended. For production support, the independent channel is the primary source.","metaTitle":"CY7C1059DV33-12ZSXQ 8Mbit Async SRAM, 12 ns, 44-TSOP II","metaDescription":"Infineon CY7C1059DV33-12ZSXQ 8Mbit asynchronous SRAM, 12 ns access time, 3V-3.6V, -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":"Tube","Technology":"SRAM - Asynchronous","Access Time":"12 ns","Memory Size":"8Mbit","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":"CY7C1059","Memory Organization":"1M x 8","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"44-TSOP II","Write Cycle Time - Word, Page":"12ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$11.7000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/d43d79a6f20521a595588512a95ca4c3.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1059DV33-12ZSXQ/alternatives.json"},"ai":{"faq":[{"question":"Is CY7C1059DV33-12ZSXQ obsolete?","answer":"Yes, Infineon lists the CY7C1059DV33-12ZSXQ as Obsolete.
