Frequently asked questions
Where can I buy CY7C1620KV18-250BZC and how do I get a price?
The CY7C1620KV18-250BZC is available to order through independent distribution. Submit an RFQ for current availability and pricing — confirmed at quote time, not a published figure.
What is the closest functional second-source for CY7C1620KV18-250BZC?
The CY7C1650KV18-450BZC is a higher-speed sibling (450 MHz vs 250 MHz) with the same 144 Mbit density, 4M × 36 organization, 1.7–1.9 V supply, and 165-FBGA footprint — it is a drop-in replacement if the bus can tolerate the faster timing.
Will CY7C1620KV18-250BZC drop into a board designed for CY7C1650KV18-450BZC?
Yes, the two parts share the same 165-FBGA footprint, supply voltage range, and memory organization. The 250 MHz part will run at the slower clock rate; no rewiring or PCB change is needed.
