The Infineon CY7C1425AV18-250BZXC is a 36Mbit synchronous SRAM built on the QDR II architecture — a dual-port memory with separate read and write data buses that eliminates bus-turnaround dead cycles. Clocked at 250 MHz and organized as 4M x 9, this part is designed for high-bandwidth buffer applications like network switches, telecom line cards, and test equipment where sustained back-to-back throughput matters more than latency. Temperature grade is commercial (0°C to 70°C), so this SRAM is suited for indoor, climate-controlled equipment — server rooms, lab instruments, telecom central offices — not for industrial floors, engine bays, or outdoor cabinets.

Frequently asked questions
Is CY7C1425AV18-250BZXC obsolete?
Yes, the CY7C1425AV18-250BZXC is officially obsolete per Infineon's lifecycle status. No factory production remains; it is sourced from surplus and broker inventory only.
What is the replacement for CY7C1425AV18-250BZXC?
Infineon has not published a direct pin-compatible successor for this specific QDR II 36Mbit 250 MHz variant. Any replacement would require a board respin to a different density, speed grade, or vendor — contact an applications engineer for a functional match.
Is CY7C1425AV18-250BZXC compatible with 1.8V systems?
Yes, the supply voltage range is 1.7V to 1.9V, making it compatible with 1.8V nominal systems. It is not 3.3V or 2.5V tolerant on the I/O rails.
What is the package of CY7C1425AV18-250BZXC?
The package is a 165-ball LBGA (15x17 mm body), also referenced as 165-FBGA. It ships in Tray format.
What is the operating voltage of CY7C1425AV18-250BZXC?
The operating supply voltage is 1.7V to 1.9V, with a nominal 1.8V rail.
