When looking at some Cypress parts, you may see that some with the prefix “MB” as in MB88151APNF-G-200-JNERE1 and some with prefix “CY” in CY88151APNF-G-200-JNERE1. What is the difference between these two part numbers?
- There is no difference. The MB is just the legacy version of the part number.
