The Cypress CY7C1525JV18-250BZXC is a 72 Mbit QDR II synchronous SRAM organized as 8M x 9, clocked at 250 MHz over a parallel interface. QDR II architecture delivers separate read and write data ports, eliminating bus-turnaround dead cycles — essential for high-throughput buffer applications like network switches, telecom line cards, and high-end test equipment where back-to-back transactions matter.
Obsolete — the sourcing reality
Any remaining stock is new-old-stock or surplus held in the independent channel. No last-time-buy window remains open.
Package and temperature — design constraints
The 165-ball FBGA (15x17 mm) is a surface-mount, fine-pitch BGA. Reball and rework require a profile matched to the MSL level on the reel label — standard lead-free soak profiles apply.
