The Infineon CY7C1548KV18-450BZI is a 72Mbit synchronous SRAM using DDR II+ architecture, organized as 4M x 18. The 450 MHz clock rate delivers back-to-back read/write throughput for high-bandwidth data buffers in network switches, routers, and telecom line cards.
At 450 MHz, the DDR II+ interface transfers data on both clock edges, effectively doubling the data rate per pin.
Supplied in a 165-ball FBGA (13x15 mm) on tray. Surface-mount only. The fine-pitch BGA requires controlled reflow profile and X-ray inspection for void-free joints — standard for high-density memory on multilayer boards.
