It uses a parallel memory interface and operates from a 3.135V to 3.6V supply. The 36-bit wide word matches common bus widths for cache tags, FIFO implementations, and packet buffers without needing to gang multiple narrower parts. At 167 MHz the cycle time is 6 ns. With a 3.4 ns access time measured from the clock edge, the data appears on the outputs with about 2.6 ns of setup margin before the next clock edge — enough for most 100-pin TQFP layouts if the trace lengths are matched. The 1M x 36 organization means a single chip delivers 36 bits per cycle, so a 64-bit memory word takes two chips plus a 32-bit chip, or four chips for a 144-bit wide datapath. The 3.135V to 3.6V supply range covers both 3.3V nominal rails and the lower end of a 3.5V supply with margin. The CY7C1440AV33-167AXC is marked obsolete by Cypress. If you need a pin-compatible drop-in for a production run, check the broader CY7C1440A family for density or speed variants that share the 100-LQFP footprint; verify the exact timing and supply compatibility against your timing budget. Housed in a 100-lead LQFP (14x20 mm body), surface-mount only. The tray shipping medium means the parts arrive in antistatic trays, not tape-and-reel; plan for pick-and-place if your line expects reeled parts.","metaTitle":"Cypress CY7C1440AV33-167AXC 36Mbit SRAM, 167 MHz, 3.4 ns","metaDescription":"Cypress CY7C1440AV33-167AXC 36Mbit synchronous SRAM, 167 MHz clock, 3.4 ns access time, 1Mx36 organization, 100-LQFP.","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":"3.4 ns","Memory Size":"36Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"100-LQFP","Product Status":"Obsolete","Clock Frequency":"167 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"3.135V ~ 3.6V","Base Product Number":"CY7C1440","Memory Organization":"1M x 36","Operating Temperature":"0°C ~ 70°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":"https://cdn.icboms.com/3b01b317321a94003d88381c3d74d550.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for CY7C1440AV33-167AXC?","answer":"The closest alternatives are other density or speed variants within the CY7C1440A family that share the same 100-LQFP footprint — verify the clock frequency, access time, and supply voltage against your timing budget before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C1440AV33-167AXC","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C1440AV33-167AXC when reusing this data.
