It clocks at 550 MHz, delivering back-to-back read/write throughput without dead cycles between transactions — the DDR II+ bus-turnaround advantage over standard synchronous SRAM. The 36-bit wide word suits networking line cards, telecom switch fabrics, and high-end test equipment where a wide data path matches the ASIC or FPGA bus natively. The part comes in a 165-ball fine-pitch BGA (13x15 mm FBGA package). At 550 MHz, the DDR II+ interface transfers data on both clock edges, so the effective data rate is 1.1 G transfers per second per pin. With a 36-bit bus, that is roughly 39.6 Gbit/s aggregate bandwidth. The synchronous pipeline means the SRAM can sustain back-to-back reads or writes without inserting idle cycles, critical for high-utilization buffer applications like packet processing. The 550 MHz rating is the maximum clock; the part also supports lower frequencies for power-sensitive modes. ## Last Buy lifecycle — sourcing reality Buyers filling a BOM line for an existing production run should secure final-order quantities through the LTB window. After that, availability shifts to the surplus and broker channel. The 165-ball LBGA (13x15 mm FBGA) is a fine-pitch BGA — standard for high-density memory devices. Surface-mount assembly; MSL level should be verified from the latest Cypress handling note.","metaTitle":"CY7C1570KV18-550BZXI 72Mbit DDR II+ SRAM, 550 MHz, 165-LBGA","metaDescription":"Infineon/Cypress CY7C1570KV18-550BZXI 72Mbit synchronous SRAM, DDR II+, 550 MHz clock, 2M x 36, 1.7-1.9V, -40 to 85°C, 165-FBGA.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Last Buy","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":"Last Time Buy","Clock Frequency":"550 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"1.7V ~ 1.9V","Base Product Number":"CY7C1570","Memory Organization":"2M x 36","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"165-FBGA (13x15)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$284.8750","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f3ac029ffc545a65cbb1ccc99598ab81.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1570KV18-550BZXI/alternatives.json"},"ai":{"faq":[{"question":"Is CY7C1570KV18-550BZXI still available for purchase?","answer":"Yes, it is available through the independent channel, but it is in Last Buy status.
