It clocks at 333 MHz and uses a parallel memory interface, running from a 1.7V to 1.9V supply. At 333 MHz the DDR II interface transfers data on both clock edges, effectively doubling the data rate per pin. For a 36-bit-wide word, that translates to over 12 Gbps of aggregate bandwidth — enough to keep a high-port-count switch fabric or a deep packet buffer fed without stalling the pipeline. The 512K x 36 organization means each access moves a full 36-bit word, which aligns well with 32-bit or 36-bit datapaths common in network processors and FPGA-based designs. If your application runs at a lower bus speed, the part still operates at the rated clock; the margin helps with signal-integrity closure on longer PCB traces. ## Package and board-level considerations The 165-ball FBGA (13x15 mm) is a fine-pitch BGA — expect 0.8 mm or 1.0 mm ball pitch depending on the specific footprint variant. The 1.7V to 1.9V core supply means you need a dedicated 1.8V rail, separate from any 3.3V or 2.5V I/O supplies on the board. For rework, the BGA requires a hot-air profile with bottom-side preheat;.","metaTitle":"Cypress CY7C1320KV18-333BZC 18Mbit DDR II SRAM, 333 MHz","metaDescription":"Cypress CY7C1320KV18-333BZC 18Mbit synchronous DDR II SRAM, 333 MHz clock, 512K x 36 organization, 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, DDR 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":"CY7C1320","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":"$30.6800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/53140c6691acfd2584a2fd1e9086db4f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1320KV18-333BZC/alternatives.json"},"ai":{"faq":[{"question":"Is CY7C1320KV18-333BZC obsolete and what is the recommended replacement?","answer":"Yes, the lifecycle status is Obsolete.
