At 450 MHz, the QDR II+ interface delivers four data words per clock cycle (two on the rising edge, two on the falling), giving an effective data rate of 1.8 Gbps per pin. For a 36-bit-wide bus, that translates to roughly 64.8 Gbit/s raw bandwidth — enough to keep a high-port-count switch fabric or a packet processor's lookup engine fed without adding pipeline stalls. The trade-off is tight signal-integrity requirements on the PCB: the 450 MHz clock needs controlled-impedance traces and matched-length routing between the SRAM and the controller. The ROHS3 compliance also keeps it usable for designs shipping into RoHS-regulated markets without a waiver. The 165-ball FBGA (13x15 mm) is a fine-pitch BGA. The 1.0 mm ball pitch is manageable with standard SMT assembly, but the part requires X-ray inspection after reflow to verify solder-joint integrity. The package is surface-mount only. No exposed thermal pad — heat dissipation relies on the BGA balls and the PCB copper plane beneath the device. For a 450 MHz part, place decoupling capacitors within 2 mm of the supply balls to keep the PDN impedance low.","metaTitle":"Infineon CY7C1265KV18-450BZXC 36Mbit QDR II+ SRAM, 450 MHz","metaDescription":"Infineon CY7C1265KV18-450BZXC 36Mbit synchronous QDR II+ SRAM, 450 MHz clock, 1.7V-1.9V supply, 165-FBGA, commercial temp.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Mfr":"Infineon Technologies","Series":"-","Package":"Tray","Technology":"SRAM - Synchronous, QDR II+","Memory Size":"36Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"165-LBGA","Product Status":"Active","Clock Frequency":"450 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"1.7V ~ 1.9V","Base Product Number":"CY7C1265","Memory Organization":"1M 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":"$25.5300","priceTiers":[{"qty":1,"price":"$25.53000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/277b6dff6a1b6061a2b90de843d6cc80.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1265KV18-450BZXC/alternatives.json"},"ai":{"faq":[{"question":"What is the clock frequency of CY7C1265KV18-450BZXC?","answer":"The clock frequency is 450 MHz.
