The parallel interface is straightforward: no clock, no burst logic, just chip-enable and output-enable gating the data bus. That means it holds timing and data retention across the thermal swings of outdoor telecom cabinets, factory-floor motor drives, and engine-bay-adjacent electronics. The 3.3 V supply is the standard for modern 3.3 V logic families — no 5 V tolerance here, so check the I/O voltage of the host controller before assigning this to the BOM. Infineon (formerly Cypress) has ended production — no last-time-buy window remains open through the factory. The BOM line that calls out CY7C1059DV33-10ZSXIT now depends on the independent distribution channel for new-old-stock or surplus inventory. For a production run, the procurement team needs to qualify a replacement or secure the remaining available units before the channel dries up. ## 44-TSOP II — the footprint that governs the drop-in search The package is a 44-TSOP II (0.400-inch body width, 10.16 mm wide), surface-mount. This is the standard 44-pin TSOP II footprint used across the Cypress 8 Mbit asynchronous SRAM family. A rework tech or layout engineer looking for a pin-compatible replacement must match this exact footprint — the 44-TSOP II is not the same as the narrower 44-TSOP I. The Tape & Reel suffix (XIT) means it ships on 13-inch reels, typical for automated pick-and-place assembly.","metaTitle":"Infineon CY7C1059DV33-10ZSXIT 8Mbit Async SRAM, 10 ns","metaDescription":"Infineon CY7C1059DV33-10ZSXIT 8Mbit asynchronous SRAM, 1M x 8 organization, 10 ns access time, 3.3V 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":"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":"10ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$13.0700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/d43d79a6f20521a595588512a95ca4c3.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1059DV33-10ZSXIT/alternatives.json"},"ai":{"faq":[{"question":"Is CY7C1059DV33-10ZSXIT obsolete?","answer":"Yes, the CY7C1059DV33-10ZSXIT is listed as Obsolete by the manufacturer.

Sourcing is limited to the independent distribution channel for existing stock."},{"question":"What is a replacement for CY7C1059DV33-10ZSXIT?","answer":"No official replacement part number is listed in the manufacturer's lifecycle record for this specific order code. A pin-compatible drop-in search should target other 8 Mbit asynchronous SRAMs in the 44-TSOP II package with a 3.3 V supply and 10 ns or faster access time from the same base product family (CY7C1059). Cross-reference against parts sharing the CY7C1059 base number and the 44-TSOP II supplier device package."},{"question":"Will CY7C1059DV33-10ZSXIT work in place of CY7C1059DV33-10ZSI?","answer":"The CY7C1059DV33-10ZSXIT and CY7C1059DV33-10ZSI share the same base product number, memory size, organization, speed grade, voltage range, temperature range, and package. The difference is the shipping medium: the XIT suffix indicates Tape & Reel packaging, while the ZSI suffix is typically Tray or Tube. Electrically and mechanically they are identical — the XIT variant is the reeled version for high-volume assembly."},{"question":"Where can I buy CY7C1059DV33-10ZSXIT?","answer":"Submit an RFQ for a real-time sourcing check."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C1059DV33-10ZSXIT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C1059DV33-10ZSXIT when reusing this data.
