For a system running at 167 MHz, that means every clock cycle moves data — no bubbles in the pipeline. The memory is organized 2M x 36, which matches the 36-bit data path common in network processors, DDR memory controllers, and high-end FPGA interfaces that need a wide word without external byte-mux logic. ## 167 MHz clock and 3.4 ns access — timing budget reality The 167 MHz clock frequency sets a 6 ns cycle period. The 3.4 ns access time leaves roughly 2.6 ns for board trace delay, clock skew, and setup time at the receiver — tight but workable with controlled-impedance routing under 4 inches. This part is not a candidate for a relaxed, multi-drop bus; it expects a point-to-point or low-load topology. At 167 MHz the flash wait-state logic is irrelevant here — SRAM has no wait states — but the output hold time relative to the clock edge still needs a signal-integrity check against the FPGA or ASIC input threshold. The 3.135V to 3.6V supply range gives about 5% margin on a nominal 3.3V rail, enough for a well-regulated POL converter but not for a shared 3.3V bus with heavy digital switching noise. ## Package and footprint — 100-LQFP, surface-mount only The CY7C1470BV33-167AXC comes in a 100-lead LQFP (14x20 mm body, 0.5 mm pitch). It is surface-mount only, so the board needs a 0.5 mm pitch land pattern with via-in-pad or dogbone fanout for the inner rows. No automotive or industrial cold-soak capability. ## Lifecycle — active, no LTB on the horizon No PCN or last-time-buy notice has been issued. The active status also means the manufacturer continues to support it with datasheets, IBIS models, and application notes — no scavenger-hunt for documentation.","metaTitle":"Cypress CY7C1470BV33-167AXC 72Mbit NoBL SRAM, 167 MHz","metaDescription":"Cypress CY7C1470BV33-167AXC 72Mbit synchronous SRAM, 167 MHz clock, 3.4 ns access, 2M x 36, 100-LQFP, commercial temp.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Mfr":"Infineon Technologies","Series":"NoBL™","Package":"Tray","Technology":"SRAM - Synchronous, SDR","Access Time":"3.4 ns","Memory Size":"72Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"100-LQFP","Product Status":"Active","Clock Frequency":"167 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"3.135V ~ 3.6V","Base Product Number":"CY7C1470","Memory Organization":"2M 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":"$170.1200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/83307e304e9f2bc3dc3842e011f87753.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1470BV33-167AXC/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between CY7C1470BV33-167AXC and CY7C1470BV33-167BXC?","answer":"The difference is the package. The 'AXC suffix indicates a 100-LQFP, while the 'BXC suffix typically refers to a 100-FBGA package. The BGA variant offers a smaller footprint and better thermal performance but requires more complex PCB routing and assembly. Both share the same 72Mbit NoBL core, 167 MHz speed grade, and commercial temperature range. The LQFP version is easier to hand-assemble and inspect."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C1470BV33-167AXC","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C1470BV33-167AXC when reusing this data.
