1 Feature Differences Between F2837x and F28P65x

The 176-pin and 100-pin are the common packages between F2837x, F2807x and F28P65x. It is possible to migrate between F2837x, F2807x and F28P65x 176-pin with the caveats in this document taken into account. A supplemental section has been added with recommendations for a PCB design to accommodate 100-pin devices for F2837x and F28P65x, to account for application development using F28P65x with F2837x device. The recommendations cover F2837x but same recommendations apply to F2807x. Consult F2807x datasheet for more details on peripherals and pins that are available.

Note: This comparison guide focuses on the superset devices: F28387 and F28P65X. Other part numbers in this product family have reduced feature support. For details specific to part numbers, see the device-specific data sheet.
