This is a high-bandwidth memory part designed for networking line cards, telecom switch fabrics, and test equipment where back-to-back read/write throughput matters and dead cycles on the bus cost performance. ## 300 MHz clock — bus margin and throughput At 300 MHz the QDR II interface delivers a 1.2 Gbps data rate per pin (double-data-rate on both read and write ports). The 4M x 9 organisation means the part handles a 9-bit-wide word; in a typical 36-bit or 72-bit memory subsystem you'll bank four or eight of these to match the data bus. ## Obsolete — sourcing from the independent channel Infineon lists the CY7C1426JV18-300BZC as Obsolete. Date-code provenance matters here: verify the parts come from a traceable lot, especially for a BGA package that cannot be visually inspected for moisture or handling damage. ## 165-FBGA footprint and rework considerations The 165-ball FBGA (15x17 mm) is a fine-pitch BGA. The package is surface-mount only, and the tray shipping medium means the parts arrive in anti-static trays.","metaTitle":"Infineon CY7C1426JV18-300BZC QDR II SRAM, 36 Mbit, 300 MHz","metaDescription":"Infineon CY7C1426JV18-300BZC QDR II synchronous SRAM, 36 Mbit (4M x 9), 300 MHz clock, parallel interface, 1.7V-1.9V supply, 0°C-70°C, 165-FBGA.","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, QDR II","Memory Size":"36Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"165-LBGA","Product Status":"Obsolete","Clock Frequency":"300 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"1.7V ~ 1.9V","Base Product Number":"CY7C1426","Memory Organization":"4M x 9","Operating Temperature":"0°C~70°C(TA)","Supplier Device Package":"165-FBGA (15x17)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$62.0600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3d883a441843b57c029d85b3883f7eb7.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1426JV18-300BZC/alternatives.json"},"ai":{"faq":[{"question":"Is CY7C1426JV18-300BZC obsolete?","answer":"Yes, Infineon lists the CY7C1426JV18-300BZC as Obsolete.

The only supply route is the independent surplus channel."},{"question":"Is CY7C1426JV18-300BZC compatible with a 1.8V supply?","answer":"Yes, the supply range is 1.7V to 1.9V, so a nominal 1.8V rail is right in the middle of the operating window."},{"question":"Can CY7C1426JV18-300BZC be used in a QDR II+ system?","answer":"This is a QDR II device, not QDR II+. QDR II+ operates at higher clock rates (up to 550 MHz) and uses a different bus protocol. While the package and supply may overlap, the timing and control logic are not directly compatible — a QDR II+ controller will not reliably interface with this part."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C1426JV18-300BZC","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C1426JV18-300BZC when reusing this data.
