72Mbit DDR II+ SRAM at 600 MHz — what the speed grade buys you
The Infineon CY7C1568XV18-600BZXC is a 72Mbit synchronous SRAM built on the DDR II+ architecture, organized as 4M x 18 bits. The 600 MHz clock rate means the memory delivers double-data-rate transfers on every clock edge, giving a peak bandwidth that keeps packet buffers and cache lines fed in high-throughput networking gear or FPGA-attached storage. The 18-bit width with a parity-friendly organization suits designs where every word carries an extra bit for error detection or sideband data. Core supply runs on a 1.7V to 1.9V rail, typical of the 1.8V domain used in modern ASICs and FPGAs — make sure your regulator holds below 1.9V absolute max at all load steps.
Package and mounting — 165-ball FBGA reality check
That said, the DDR II+ SRAM family is a mature product line; Infineon (formerly Cypress) still supports it, but lead times can stretch when fab loads shift. No stock or price numbers here — those change daily — but the part is findable.
