The 32-TSOP I footprint is a standard JEDEC outline used across many 1 Mbit asynchronous SRAMs, so the board layout should accept other 32-TSOP I parts if a second source is needed.","metaTitle":"Infineon CY7C109B-12ZXCT 1Mbit Async SRAM, 12 ns, 32-TSOP I","metaDescription":"Infineon CY7C109B-12ZXCT 1Mbit (128K x 8) asynchronous SRAM with 12 ns access time, 4.5V-5.5V supply, 32-TSOP I package.","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":"12 ns","Memory Size":"1Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"32-TFSOP (0.724\\\", 18.40mm Width)","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"4.5V ~ 5.5V","Base Product Number":"CY7C109","Memory Organization":"128K x 8","Operating Temperature":"0°C~70°C(TA)","Supplier Device Package":"32-TSOP I","Write Cycle Time - Word, Page":"12ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9348473d542f5020948178887c70842d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C109B-12ZXCT/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for CY7C109B-12ZXCT?","answer":"Infineon has not published an official successor order code for this part."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C109B-12ZXCT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C109B-12ZXCT when reusing this data.
