Frequently asked questions
Our board was designed around the CY7C1650KV18-450BZC — can the CY7C1645KV18-450BZXI drop in as a pin-compatible replacement?
Both parts share the same 144 Mbit density, 4M x 36 organization, 450 MHz clock, and 1.7 V supply. The only ledger-cited difference is temperature grade: the BZC is rated 0 to 70 °C (commercial), the BZXI is rated -40 to 85 °C (industrial). If the system ambient stays below 70 °C, the BZXI is a functional equivalent and should drop into the same footprint. If the deployment environment runs below 0 °C or above 70 °C, the BZXI is required and the BZC would not survive — a respin is not needed, but the BOM line needs to specify the correct temperature grade for the target application.
