That is roughly 22% higher throughput than the 450 MHz CY7C1650KV18-450BZC, which runs the same 4M x 36 organization at a lower clock. The trade-off is tighter timing closure on the PCB — the 1.8 ns cycle time leaves less margin for trace-length mismatch and requires controlled-impedance routing on all data and address lines. The 165-ball FBGA (15x17 mm) uses a 1.0 mm ball pitch typical of high-density SRAM packages. The package has no exposed thermal pad — all heat dissipation is through the solder balls and the PCB copper planes. Place at least four 4.7 µF ceramic decoupling capacitors within 5 mm of the ball array on the 1.8 V supply rail to keep the transient response clean at 550 MHz switching. It is not qualified for industrial or automotive temperature ranges — if the design sees -40°C or +85°C, look at the industrial-grade variants in the same family.","metaTitle":"Infineon CY7C2665KV18-550BZXC SRAM, 144Mbit, 550 MHz","metaDescription":"Infineon CY7C2665KV18-550BZXC synchronous SRAM, 144 Mbit (4M x 36), 550 MHz clock, QDR II+ architecture, 1.7V–1.9V supply, 165-FBGA.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Mfr":"Infineon Technologies","Series":"-","Package":"Tray","Technology":"SRAM - Synchronous, QDR II+","Memory Size":"144Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"165-LBGA","Product Status":"Active","Clock Frequency":"550 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"1.7V ~ 1.9V","Base Product Number":"CY7C2665","Memory Organization":"4M x 36","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"165-FBGA (15x17)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$356.6100","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/de7713fce0919e9c3cb64ff248f7fd20.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C2665KV18-550BZXC/alternatives.json"},"ai":{"faq":[{"question":"What is the clock frequency of CY7C2665KV18-550BZXC?","answer":"The clock frequency is 550 MHz, supporting a peak data rate of 1.1 G transfers per second per pin on the 36-bit bus."},{"question":"What is the equivalent part for CY7C2665KV18-550BZXC?","answer":"The CY7C1650KV18-450BZC is a functional peer with the same 144 Mbit density and 4M x 36 organization, but at a 450 MHz clock — a 100 MHz step down.
