Product details

450 MHz QDR II+ SRAM for high-throughput line-rate buffers

It is organized as 8M x 18. The QDR II+ interface eliminates the dead cycle between read and write turns that older common-I/O SRAMs require, so the bus stays at full utilization.

The 8M x 18 organization gives a total of 144 Mbit. That is sized for deep packet buffers or large look-up tables.

That covers indoor telecom central offices, data-centre switches, and benchtop test equipment. For designs that see outdoor cabinets or factory-floor heat, the industrial-temperature variant CY7C2663KV18-450BZI (-40°C to 85°C) is the right pick; same 450 MHz speed, same 144 Mbit density, same footprint.

Housed in a 165-ball FBGA, body size 15 mm x 17 mm. The footprint matches the rest of the CY7C2663 family.

Frequently asked questions

What is the clock speed of CY7C2663KV18-450BZXC?

The CY7C2663KV18-450BZXC operates at a 450 MHz clock frequency, giving 900 Mbps per data pin on the QDR II+ double-data-rate interface.

Where can I buy CY7C2663KV18-450BZXC?

The CY7C2663KV18-450BZXC is sourced and quoted to order through independent distribution. Submit an RFQ for current availability and pricing.

What is the package type and footprint of CY7C2663KV18-450BZXC?

It comes in a 165-ball FBGA (15 mm x 17 mm body), 1.0 mm ball pitch. The footprint is shared across the CY7C2663 speed-grade family.

Can I replace CY7C2663KV18-450BZXC with CY7C2663KV18-400BZXC?

The 400 MHz speed grade is a drop-in replacement by footprint and supply voltage, but the lower clock reduces peak throughput. Verify that the slower bus meets your line-rate or latency budget before substituting.
