For a system architect, this sets the read-cycle window when interfacing with a 5 V logic controller or FPGA. At 5 V nominal, the address-to-data valid delay is tight enough for most 50 MHz-class buses, but you should verify hold times against the memory controller's setup requirements. ## Package and temperature — design-in constraints The 32-TFSOP package (0.724\" body width, 18.40 mm) is a surface-mount footprint common to many 1 Mbit asynchronous SRAMs. The Tape & Reel supply form suits automated pick-and-place assembly.","metaTitle":"Infineon CY7C109B-15ZXCT 1Mbit Async SRAM, 15 ns","metaDescription":"Infineon CY7C109B-15ZXCT 1Mbit asynchronous SRAM, 15 ns access time, 128K x 8 organization, 4.5V-5.5V supply, 0°C-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":"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":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9348473d542f5020948178887c70842d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C109B-15ZXCT/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for CY7C109B-15ZXCT?","answer":"Any replacement must be qualified against the 15 ns access time, 128K x 8 organization, and 32-TFSOP footprint."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C109B-15ZXCT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C109B-15ZXCT when reusing this data.
