PIC16C57C → 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.

Table 1 shows the considerations that must be taken into account when migrating from the PIC16C57C to the

PIC16F57.
