It runs from a 1.7 V to 1.9 V supply and clocks at 550 MHz over a parallel interface. This is a high-bandwidth memory part aimed at networking gear — switches, routers, and line cards — where the QDR II+ double-data-rate read and write ports eliminate bus-turnaround dead cycles, keeping the pipeline full. The 36-bit word width maps directly to a 36-bit data bus common in packet-processing ASICs and FPGAs, so no external byte-lane muxing is needed. That restricts this part to indoor, climate-controlled environments: data-centre networking, lab instrumentation, office telecom. No automotive under-hood, no outdoor base station, no factory floor without a conditioned enclosure. If your application sees extended temperature, look for the industrial-grade variant in the QDR II+ family.","metaTitle":"Infineon CY7C1665KV18-550BZXC SRAM, 144Mbit QDR II+, 550 MHz","metaDescription":"Infineon CY7C1665KV18-550BZXC synchronous SRAM, 144Mbit (4M x 36), QDR II+, 550 MHz clock, 1.7V-1.9V, 165-FBGA, 0°C to 70°C.
