Frequently asked questions
Can I substitute the CY7C1512KV18-250BZC (commercial 0°C to 70°C) for the 333BZXI on the same board layout?
The package footprint is the same, but the 333BZXI carries a -40°C to 85°C industrial temperature rating that the 250BZC does not. If the end environment is industrial or outdoor, or the procurement spec requires an industrial grade, the BZXI part is the correct line item. The 250BZC may function in a benign thermal environment, but that is a design decision, not a guaranteed drop-in swap.
Does the 333BZXI share the same pinout and package footprint as the 250BZC?
The physical footprint is the same 165-FBGA (13×15 mm) with the same ball count and pitch. However, the 333 MHz speed grade introduces signal-integrity constraints — controlled-impedance traces and byte-lane length matching — that the 250 MHz variant does not require to the same degree. A board validated at 250 MHz cannot simply be stuffed with the 333BZXI without re-qualification of the memory interface.
