This is not a part you can design into a new build; it is a service-and-repair or last-time-buy fill for existing boards that already carry the footprint and timing budget. ## 133 MHz clock, 6.5 ns access — the timing budget This synchronous SDR SRAM is clocked at 133 MHz with a 6.5 ns access time. The parallel interface means the address, data, and control signals share a common bus. This is a flow-through or pipelined synchronous architecture — the registered inputs latch on the clock rising edge, and the output registers update synchronously. No dead cycles on back-to-back reads if the pipeline is managed correctly. ## 2 Mbit organized 128K x 18 — fit check The 2 Mbit density is organized as 128K words of 18 bits each. ## Package and temperature — board-fit constraints Supplied in a 100-TQFP (14x20 mm) package, surface-mount. Supply voltage range is 3.15V to 3.6V, nominally 3.3V. Core and I/O share the same rail. Decoupling should follow the datasheet recommendation for synchronous SRAM — typically one 0.1 µF ceramic per VDD pin pair, plus a bulk 10 µF on the board. ## Sourcing this obsolete SRAM Because this part is obsolete, the franchised distribution channel no longer stocks it. Availability is through independent distributors who hold verified new-old-stock or surplus inventory. If your BOM needs a production-quantity fill or a last-time-buy bridge, let us know the target quantity and date-code window.","metaTitle":"Cypress CY7C1324H-133AXCT 2Mbit Sync SRAM, 133 MHz, 6.5 ns","metaDescription":"Cypress CY7C1324H-133AXCT synchronous SDR SRAM, 2Mbit (128Kx18), 133 MHz clock, 6.5 ns access, 100-TQFP, 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 - Synchronous, SDR","Access Time":"6.5 ns","Memory Size":"2Mbit","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":"CY7C1324","Memory Organization":"128K x 18","Operating Temperature":"0°C~70°C(TA)","Supplier Device Package":"100-TQFP (14x20)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.3500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b6094fc8902abbb681a8af6e879c1d41.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1324H-133AXCT/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C1324H-133AXCT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C1324H-133AXCT when reusing this data.
