It clocks at 550 MHz, which gives it the bandwidth to serve as a high-speed data buffer in network switches, test instrumentation, and telecom line cards where read-write turnaround must be minimized. A 550 MHz clock rate on a DDR II+ SRAM means data is transferred on both edges, so the effective data rate is double the clock. For a 4M x 18 part, that translates to a peak bandwidth of about 1.98 GB/s (550 MHz × 2 edges × 18 bits ÷ 8). That throughput matters when the memory sits between a high-speed ASIC and a backplane — you avoid dead cycles on the bus that a slower QDR or NoBL part would introduce. Cypress (now part of Infineon) no longer manufactures the CY7C1568KV18-550BZXC. The supply channel for this part is surplus and broker inventory — sealed reels with consistent date-codes are the preferred lot condition. ## 165-FBGA footprint and temperature grade The package is a 165-ball FBGA, 13x15 mm body, surface-mount only. The 1.7V to 1.9V supply rail is tighter than the older 2.5V QDR parts, so the PCB power distribution needs a clean 1.8V rail with adequate decoupling.","metaTitle":"CY7C1568KV18-550BZXC SRAM, 72Mbit, 550 MHz, DDR II+","metaDescription":"Cypress CY7C1568KV18-550BZXC 72Mbit synchronous DDR II+ SRAM, 550 MHz clock, 4M x 18 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":"72Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"165-LBGA","Product Status":"Obsolete","Clock Frequency":"550 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"1.7V ~ 1.9V","Base Product Number":"CY7C1568","Memory Organization":"4M x 18","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"165-FBGA (13x15)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$344.1700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/316d3cb111c6735e5421a10b6975ff82.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1568KV18-550BZXC/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C1568KV18-550BZXC","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C1568KV18-550BZXC when reusing this data.
