At 300 MHz the DDR II interface delivers a 600 MT/s data rate per pin. The memory controller must close timing with a 1.7 ns clock period and half-cycle setup/hold windows. Board-level signal integrity — trace impedance, stub length, and VTT termination — becomes critical at this speed. The 1M x 18 organisation gives an 18-bit data bus, typical for networking packet buffers or high-speed data acquisition where a narrow but fast bus feeds a wide internal pipeline. No separate VDDQ is needed. The low voltage reduces dynamic power but also narrows noise margins — a clean, well-decoupled 1.8 V plane with tight regulation is expected. ## Package and footprint — 165-FBGA (13x15 mm) The same ballout is shared across the CY7C1393JV18 family's speed grades, so a board designed for the 250 MHz variant can accept the 300 MHz part without a layout change.","metaTitle":"Cypress CY7C1393JV18-300BZXC DDR II SRAM, 18Mbit, 300MHz","metaDescription":"Cypress CY7C1393JV18-300BZXC synchronous DDR II SRAM, 18Mbit (1M x 18), 300MHz clock, 1.7V-1.9V supply, 165-FBGA, 0-70°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"title":"CY7C1393JV18-300BZXC","Package":"Tray","Technology":"SRAM - Synchronous, DDR II","Memory Size":"18Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"165-LBGA","Clock Frequency":"300 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"1.7V ~ 1.9V","Base Product Number":"CY7C1393","Memory Organization":"1M x 18","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"165-FBGA (13x15)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$37.5500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/8de72dae436a7b4fff147e5632dbd5be.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1393JV18-300BZXC/alternatives.json"},"ai":{"faq":[{"question":"Is CY7C1393JV18-300BZXC obsolete?","answer":"Yes, the CY7C1393JV18-300BZXC is listed as Obsolete."},{"question":"Can CY7C1393JV18-300BZXC be substituted with CY7C1393JV18-250BZXC?","answer":"The CY7C1393JV18-250BZXC is the same Cypress DDR II SRAM in the same 165-FBGA package and 1M x 18 organisation, but rated at 250 MHz instead of 300 MHz.
