That means it is specced for office or lab ambient, not an unventilated enclosure or outdoor cabinet. Packaged in a 32-TFSOP (0.724\", 18.40 mm width) — the 32-TSOP I footprint. The supplier device package is 32-TSOP I, the same body. Bag packaging, not tape-and-reel, so expect loose units for prototype or low-volume builds. ## Obsolete — spot-market sourcing only Infineon lists the CY7C109B-15ZXC as obsolete. Each lot is date-code and quantity confirmed at quote time. No pin-compatible second-source or drop-in replacement is recorded in the manufacturer's cross-reference data.","metaTitle":"Infineon CY7C109B-15ZXC 1Mbit Async SRAM, 15ns","metaDescription":"Infineon CY7C109B-15ZXC 1Mbit asynchronous SRAM, 128K x 8, 15ns access, 4.5-5.5V, 32-TSOP I.","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":"Bag","Technology":"SRAM - Asynchronous","Access Time":"15 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":"15ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.4000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/614cae6aa7d2f85f36b2b9854b99b404.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C109B-15ZXC/alternatives.json"},"ai":{"faq":[{"question":"What is the memory organization and access time of the CY7C109B-15ZXC?","answer":"It is a 1 Mbit asynchronous SRAM organized as 128K x 8 bits, with a 15 ns access time and a 15 ns write cycle time."},{"question":"What package does the CY7C109B-15ZXC come in?","answer":"It is supplied in a 32-TFSOP (0.724\", 18.40 mm width) — the 32-TSOP I footprint.
