PIC16F87X PIC16F87XA Migration
This document intended describe functional differences electrical specification differences present when migrating from device next. Except items listed Table PIC16F87XA designed pin-to-pin, functionally compatible with PIC16F87X product family. Table shows considerations that must taken into account when migrating from PIC16F87X PIC16F87XA. Table shows electrical timing differences.
This device been designed perform parameters data sheet. been tested electrical specification designed determine conformance with these parameters. process differences manufacture this device, this device have different performance characteristics than earlier version. These differences cause this device perform differently your application than earlier version this device.
user should verify that device oscillator starts performs expected. Adjusting loading capacitor values and/or oscillator mode required.
