The 2.6 ns access time from clock edge means the data output settles well within the half-cycle window, giving the controller or FPGA setup margin on the read data bus. For a 36-bit parallel bus this margin is the difference between a clean timing closure and a respin — especially when routing through a BGA breakout or across a backplane. Infineon (Cypress) lists the CY7C1444AV33-250AXI as Obsolete, meaning it is no longer in production and has passed any last-time-buy window. Each unit is sourced against an RFQ, with date codes and condition verified before shipment. ## Second-source and replacement reality There is no official second-source or pin-compatible drop-in replacement for the CY7C1444AV33-250AXI from another manufacturer. The base product number CY7C1444 covers several speed and temperature variants (e.g., -200 vs -250, commercial vs industrial), but all share the same 100-TQFP footprint and 1M x 36 organization. For a new design, a newer-generation synchronous SRAM family (such as Cypress's own 72Mbit or NoBL parts) would require a PCB and timing rework.","metaTitle":"CY7C1444AV33-250AXI 36Mbit SRAM, 250 MHz, 2.6 ns, Obsolete","metaDescription":"Infineon (Cypress) CY7C1444AV33-250AXI 36Mbit synchronous SDR SRAM, 250 MHz clock, 2.6 ns access time, 100-TQFP, industrial temp.","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":"2.6 ns","Memory Size":"36Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"100-LQFP","Product Status":"Obsolete","Clock Frequency":"250 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"3.135V ~ 3.6V","Base Product Number":"CY7C1444","Memory Organization":"1M x 36","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"100-TQFP (14x20)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C1444AV33-250AXI","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C1444AV33-250AXI when reusing this data.
