Product details

633 MHz DDR II SRAM for high-throughput buffers

The Infineon CY7C1270XV18-633BZXC is a 36Mbit Synchronous DDR II SRAM organized as 1M x 36, clocked at 633 MHz. It operates from a 1.7V to 1.9V supply and comes in a 165-LBGA package.

633 MHz clock — timing closure and bus margin

The 633 MHz clock rate is the headline spec. The 1.7V to 1.9V supply range means this part runs on a nominal 1.8V rail.

That is commercial grade, so this part is suited for office-environment networking gear, lab instruments, and data-center equipment.

Frequently asked questions

What is the closest functional second-source to CY7C1270XV18-633BZXC?

The CY7C1265XV18-633BZXC is a peer with the same 36Mbit density, 633 MHz clock, 1M x 36 organization, and 0°C to 70°C temperature range, making it a direct functional alternate for dual-sourcing.

Will CY7C1270XV18-633BZXC drop into a board designed for CY7C1265XV18-633BZXC?

Yes, both parts share the same 36Mbit density, 633 MHz clock, 1M x 36 organization, 1.7V–1.9V supply, and 0°C to 70°C temperature range, so they are pin-compatible and functionally interchangeable without board rework.
