The part runs on a 1.7 V to 1.9 V core supply and is housed in a 165-ball FBGA (13x15 mm). The commercial temperature range (0°C to 70°C) targets indoor, climate-controlled environments — data center line cards, telecom central-office blades, and ATE test-head memory.

Product details
Frequently asked questions
Is CY7C2564XV18-450BZXC still active or obsolete?
The CY7C2564XV18-450BZXC is marked EOL hot — Infineon has discontinued production and the last-time-buy window is closed. Available stock is now limited to surplus and independent distributor inventory.
What is the speed grade of CY7C2564XV18-450BZXC?
The speed grade is -450, meaning a 450 MHz clock frequency. On a QDR II+ SRAM this yields a 900 MT/s data rate per port.
What is the voltage range for CY7C2564XV18-450BZXC?
The supply voltage range is 1.7 V to 1.9 V.
What is the replacement for CY7C2564XV18-450BZXC?
No official replacement part number is listed in the lifecycle record. For a pin-compatible alternative, check the same QDR II+ family at the same 72 Mbit density and 450 MHz speed grade, but no specific cross-reference is confirmed.
