Frequently asked questions
Does the CY7C1643KV18-450BZI swap directly with the CY7C2663KV18-450BZI on the same board layout?
Both parts share 8M x 18 organization, 450MHz clock, and 165-LBGA footprint, making them pin-compatible at matching speed grade. The CY7C1643KV18-450BZI is rated to -40°C to 85°C; the CY7C2663KV18-450BZI extends to 105°C. If the thermal headroom is sufficient, a validated layout for one is valid for the other without spin — the swap viability is thermal, not electrical or mechanical.
