Product details

72 Mbit DDR II SRAM — what this part does

The CY7C1568V18-400BZXC: 72 Mbit synchronous SRAM with DDR II interface, organized as 2M x 36. Clocks at 400 MHz.

Data transfers on both clock edges at 400 MHz. The 165-LBGA package requires careful layout.

This part is marked Obsolete by the manufacturer. If your design can tolerate a different package or density, a cross-reference search against the 72 Mbit DDR II family may yield an active alternative, but no pin-compatible drop-in is documented here.

Frequently asked questions

What is the replacement for CY7C1568V18-400BZXC?

No official replacement order code is listed in the lifecycle record. A cross-reference search within the 72 Mbit DDR II SRAM family may identify a functionally similar part, but no pin-compatible drop-in is documented here.

Where can I buy CY7C1568V18-400BZXC?

This obsolete part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

What is the difference between CY7C1568V18-400BZXC and CY7C1568V18-400BZXI?

The suffix 'C' indicates the commercial temperature range (0°C to 70°C), while the 'I' suffix typically denotes an industrial temperature range (-40°C to 85°C). The memory density, organization, and clock speed are the same.
