PIC16F57 Migration
DEVICE MIGRATIONS
This document is intended to describe the functional differences that are present when migrating from the PIC16C57C
to the PIC16F57.
Note 1:
This device has been designed to perform to the parameters of its data sheet. It has been tested to an
electrical specification designed to determine its conformance with these parameters. Due to process
differences in the manufacture of this device, this device may have different performance characteristics
than its earlier version. These differences may cause this device to perform differently in your application
than the earlier version of this device.
2:
The user should verify that the device oscillator starts and performs as expected. Adjusting the loading
capacitor values and/or the Oscillator mode may be required.
