Product details

633 MHz QDR II+ SRAM — what the clock rate buys

The 633 MHz clock rate delivers a burst bandwidth that keeps network processors and switch ASICs fed without wait states — the QDR II+ bus eliminates the dead cycles that older QDR and DDR SRAMs incur during read-write turnaround. This part is designed for high-throughput data buffers in telecom line cards, test equipment, and high-end computing where every cycle of memory bandwidth matters.

Supply and temperature — fit for controlled environments

Package — 165-ball FBGA

Housed in a 165-ball FBGA measuring 13 x 15 mm (supplier device package 165-FBGA), this is a surface-mount BGA that requires reflow soldering and X-ray inspection for ball void and alignment. The tray shipping medium means the parts arrive in anti-static trays, not tape-and-reel — factor that into pick-and-place feeder setup if you are running high-volume assembly.

Frequently asked questions

What is the difference between QDR and QDR II+?

QDR II+ is an evolution of the QDR (Quad Data Rate) architecture that eliminates the bus-turnaround dead cycles between read and write operations. This allows back-to-back transactions at full clock rate, which is essential for sustained throughput in network processors and switch fabrics.

Can I use CY7C1565XV18-633BZXC as a replacement for CY7C1565XV18-600BZXC?

The CY7C1565XV18-633BZXC runs at 633 MHz versus 600 MHz for the -600BZXC variant. Both share the same 72 Mbit density, 2M x 36 organization, 165-FBGA package, and supply range. The 633 MHz part is a drop-in speed upgrade, but verify timing closure at the higher clock rate in your system before substituting.
