72 Mbit QDR II SRAM — 200 MHz, 8M x 9, commercial temp
The Cypress CY7C1525V18-200BZXC is a 72 Mbit synchronous SRAM built on QDR II (Quad Data Rate) architecture, organized as 8M words by 9 bits. The 200 MHz clock rate delivers back-to-back read and write transactions without bus-turnaround dead cycles — the defining advantage of the QDR II interface over traditional NoBL or DDR SRAM in high-throughput applications like network packet buffers, FPGA cache, and telecom line cards. Supply range is 1.7 V to 1.9 V, and the part is housed in a 165-ball FBGA (13x15 mm) for surface-mount assembly.
Obsolete — last-time-buy sourcing required
Package and assembly — 165-FBGA
The 165-ball FBGA (13x15 mm) is a fine-pitch BGA. Requires reflow soldering with a controlled profile; post-solder X-ray inspection is recommended.
