72 Mbit DDR II SRAM at 300 MHz — pipeline buffer staple
The Cypress CY7C1518JV18-300BZC is a 72 Mbit synchronous SRAM with a DDR II interface, organized as 4 M x 18 bits. Clocked at 300 MHz, it delivers back-to-back read-write throughput without dead cycles — the kind of bandwidth a high-end network switch or test head needs for a deep packet buffer.
Package is a 165-ball FBGA (15x17 mm), surface-mount. Verify pinout before board layout due to tight DDR II signal timing.
Commercial temperature only — indoor or conditioned rack
No under-hood or outdoor deployment without an enclosure heater.
