Product details

Its 450 MHz clock rate delivers back-to-back read/write throughput without dead cycles, which is the primary reason this part was selected for high-bandwidth FPGA and ASIC memory interfaces in networking and telecom line cards.

No last-time-buy window remains open.

165-ball FBGA — footprint and rework considerations

The 165-ball FBGA (13x15 mm body) uses a 1.0 mm ball pitch typical of high-density SRAM packages. The supplier device package is 165-FBGA (13x15). For rework, a pre-bake at 125°C for 24 hours is standard if the floor-life window has been exceeded.

Frequently asked questions

Is CY7C1550KV18-450BZC obsolete?

Yes, the lifecycle status is Obsolete. Procurement must rely on surplus or broker-channel inventory.

What is the replacement for CY7C1550KV18-450BZC?

No official replacement order code is recorded. For a pin-compatible alternative within the same Cypress DDR II+ family, a cross-reference search against the 72 Mbit density and 450 MHz speed grade is recommended, but no specific part is confirmed as a drop-in substitute.
