The 8 mm body width and 0.5 mm pin pitch are standard for this density class. The supplier device package is 32-TSOP I. That limits deployment to indoor, temperature-controlled environments — office equipment, test instrumentation, and telecom central-office gear. ## Lifecycle — obsolete, sourced through independent channels Cypress lists the CY7C109BN-20ZXCT as obsolete. For BOM lines that still require this exact order code, procurement must go through surplus or broker distribution.","metaTitle":"Cypress CY7C109BN-20ZXCT 1Mbit Async SRAM, 20 ns, 32-TSOP I","metaDescription":"Cypress CY7C109BN-20ZXCT 1Mbit (128K x 8) asynchronous SRAM, 20 ns access time, 4.5-5.5V, 32-TSOP I, 0-70°C.","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":"20 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":"20ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/df0c16f2621ae784bba1c4b3fe12b975.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C109BN-20ZXCT/alternatives.json"},"ai":{"faq":[{"question":"Is CY7C109BN-20ZXCT obsolete and what is its direct replacement?","answer":"Yes, the CY7C109BN-20ZXCT is obsolete per Cypress. No official direct replacement order code is provided in the record. For a pin-compatible alternative, consider other 128K x 8 asynchronous SRAMs in 32-TSOP I from vendors like ISSI or Alliance — verify the 20 ns speed grade and 4.5-5.5V supply compatibility against your specific timing and voltage requirements."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C109BN-20ZXCT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C109BN-20ZXCT when reusing this data.
