This is a volatile memory — data is retained only while power is applied. It is not specified for industrial or automotive temperature extremes. ## 32-TSOP I surface-mount footprint Supplied in a 32-TFSOP package (0.724\" body width, 18.40mm wide) with a 32-TSOP I supplier device package designation. The surface-mount form factor suits automated assembly lines. The shipping medium is Tray, which is typical for SRAMs of this density and package style — not a selection parameter, but relevant for feeder setup and moisture-sensitivity handling.","metaTitle":"Infineon CY7C109BN-12ZXC 1Mbit Async SRAM, 12 ns, 32-TSOP I","metaDescription":"Infineon CY7C109BN-12ZXC 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":"Tray","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/df0c16f2621ae784bba1c4b3fe12b975.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C109BN-12ZXC/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for CY7C109BN-12ZXC?","answer":"For new designs, evaluate Infineon's current asynchronous SRAM portfolio for a form-fit-function alternative, but verify pin compatibility and timing against your specific bus interface."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C109BN-12ZXC","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C109BN-12ZXC when reusing this data.
