Sourcing shifts entirely to the independent market: surplus inventory, broker channels, and verified stock from distribution partners who hold legacy SRAM. The CY7C1314KV18-333BZC is a 18 Mbit synchronous SRAM using the QDR II (Quad Data Rate II) architecture. The memory is organized as 512K x 36, giving a 36-bit wide data bus that suits high-throughput applications like network packet buffers, cache memory for ASICs or FPGAs, and telecom line cards. The 333 MHz clock frequency means the device delivers a peak bandwidth of roughly 2.4 GB/s (333 MHz x 36 bits x 2 for DDR reads/writes, accounting for the separate read and write ports). That bandwidth matters when the design needs sustained back-to-back transactions without dead cycles — QDR II eliminates the bus-turnaround penalty of traditional SRAM by using dedicated read and write ports. The supply range is 1.7V to 1.9V, which aligns with 1.8V nominal core logic; the 165-ball FBGA (13x15 mm) footprint requires a multi-layer PCB with careful signal-integrity routing for the high-speed bus. ## Package and temperature grade — design constraints The 165-ball FBGA (13x15 mm) package is a fine-pitch BGA.","metaTitle":"Cypress CY7C1314KV18-333BZC QDR II SRAM, 18 Mbit, 333 MHz","metaDescription":"Cypress CY7C1314KV18-333BZC is a 18 Mbit synchronous QDR II SRAM, 333 MHz clock, 512K x 36, 1.7V–1.9V, 165-ball 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":"18Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"165-LBGA","Product Status":"Obsolete","Clock Frequency":"333 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"1.7V ~ 1.9V","Base Product Number":"CY7C1314","Memory Organization":"512K x 36","Operating Temperature":"0°C~70°C(TA)","Supplier Device Package":"165-FBGA (13x15)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$28.3200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/dea3bcace4592b08079c9a8b90f16dd7.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1314KV18-333BZC/alternatives.json"},"ai":{"faq":[{"question":"Is CY7C1314KV18-333BZC obsolete?","answer":"Yes, the CY7C1314KV18-333BZC is listed as Obsolete by Cypress (Infineon).
