PIC16F83 PIC16F84A Migration
This document intended describe functional differences electrical specification differences that present when migrating from device next. Table shows considerations that must taken into account when migrating from PIC16F83 PIC16F84A. 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.

PIC16F83 PIC16F84A FUNCTIONAL DIFFERENCES
Differences from PIC16F83 Program Memory (FLASH): PIC16F83 words. PIC16F84A 1024 words. Data Memory (RAM): PIC16F83 bytes. PIC16F84A bytes.
Oscillator Legend:
PIC16F83 oscillator MHz. PIC16F84A oscillator MHz. Issues exist with regard application circuit. Issues exist with regard user program.
MEMORY
Program addressing paging PIC16F83 upwardly compatible with PIC16F84A. code changes required. SFR's remain same addresses, performing same functions both devices. Data space addressing banking PIC16F83 upwardly compatible with PIC16F84A. code changes required.
OSCILLATOR
PIC16F84A crystals MHz, resulting double execution speed. changes code, other than timing concerns, required. changes configuration word required. crystal loading capacitors need adjusted higher speed crystal, verifying oscillator operation same speed already recommended transition from PIC16F83 PIC16F84A.

Note following details code protection feature PICmicro MCUs. PICmicro family meets specifications contained Microchip Data Sheet. Microchip believes that family PICmicro microcontrollers most secure products kind market today, when used intended manner under normal conditions. There dishonest possibly illegal methods used breach code protection feature. these methods, knowledge, require using PICmicro microcontroller manner outside operating specifications contained data sheet. person doing engaged theft intellectual property. Microchip willing work with customer concerned about integrity their code. Neither Microchip other semiconductor manufacturer guarantee security their code. Code protection does mean that guaranteeing product "unbreakable". Code protection constantly evolving. Microchip committed continuously improving code protection features product.
