The parallel interface simplifies timing closure compared to a DDR variant, but the bus width occupies 32 data lines plus address and control. ## Sourcing reality for an obsolete line Sourcing is limited to independent distributors and the open market.","metaTitle":"CY7C1339G-133AXE SRAM – 4Mbit, 133 MHz, 4 ns, Obsolete","metaDescription":"Infineon CY7C1339G-133AXE synchronous SRAM, 4Mbit, 133 MHz clock, 4 ns access time, 128K x 32, -40°C to 125°C, 100-TQFP.","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 - Synchronous, SDR","Access Time":"4 ns","Memory Size":"4Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"100-LQFP","Product Status":"Obsolete","Clock Frequency":"133 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"3.15V ~ 3.6V","Base Product Number":"CY7C1339","Memory Organization":"128K x 32","Operating Temperature":"-40°C~125°C(TA)","Supplier Device Package":"100-TQFP (14x20)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/0fcfc6c1e042b488c0c7722e2b529d07.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1339G-133AXE/alternatives.json"},"ai":{"faq":[{"question":"What is the clock frequency and access time of the CY7C1339G-133AXE?","answer":"It operates at 133 MHz clock frequency with a 4 ns access time, making it suitable for high-speed cache or buffer applications."},{"question":"What is the temperature range for the CY7C1339G-133AXE?","answer":"It is rated for -40 °C to 125 °C, covering industrial and automotive under-hood environments."},{"question":"What package does the CY7C1339G-133AXE come in?","answer":"It is supplied in a 100-TQFP (14 x 20 mm) package on tray."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C1339G-133AXE","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C1339G-133AXE when reusing this data.
