The PIC16F84A microcontroller, developed by Microchip Technology, is one of the most popular and widely used chips in embedded applications, known for its flash memory, EEPROM storage, and ease of programming. However, many PIC16F84A chips are delivered with protected firmware, making it difficult to access or modify the internal binary. At Circuit Engineering Co., LTD, we specialize in Copy IC PIC16F84A Binary services, helping clients readout, decrypt, and restore locked microcontrollers by using advanced techniques tailored to this specific IC.

माइक्रोचिप टेक्नोलॉजी द्वारा विकसित PIC16F84A माइक्रोकंट्रोलर, एम्बेडेड अनुप्रयोगों में सबसे लोकप्रिय और व्यापक रूप से उपयोग किए जाने वाले चिप्स में से एक है, जो अपनी फ्लैश मेमोरी, EEPROM स्टोरेज और प्रोग्रामिंग में आसानी के लिए जाना जाता है। हालाँकि, कई PIC16F84A चिप्स को सुरक्षित फ़र्मवेयर के साथ डिलीवर किया जाता है, जिससे आंतरिक बाइनरी तक पहुँचना या उसे संशोधित करना मुश्किल हो जाता है। सर्किट इंजीनियरिंग कंपनी, लिमिटेड में, हम कॉपी आईसी PIC16F84A बाइनरी सेवाओं में विशेषज्ञ हैं, जो ग्राहकों को इस विशिष्ट आईसी के अनुरूप उन्नत तकनीकों का उपयोग करके लॉक किए गए माइक्रोकंट्रोलर को रीडआउट, डिक्रिप्ट और पुनर्स्थापित करने में मदद करते हैं।

Unlike older OTP (One-Time Programmable) chips like the PIC16C554, the PIC16F84A features flash-based memory, which allows the program to be rewritten multiple times. This flash memory, however, is often encrypted, secured, or protected by code-protection bits to prevent easy access. Standard reverse engineering methods used for other microcontrollers are often ineffective. That’s why specialized approaches like decapsulation (physical chip opening), memory charge analysis, or optical imaging are necessary to break and decode the firmware stored inside.

PIC16C554와 같은 구형 OTP(One-Time Programmable) 칩과 달리 PIC16F84A는 플래시 기반 메모리를 사용하여 프로그램을 여러 번 다시 작성할 수 있습니다. 하지만 이 플래시 메모리는 쉽게 접근할 수 없도록 암호화, 보안 또는 코드 보호 비트로 보호되는 경우가 많습니다. 다른 마이크로컨트롤러에 사용되는 표준 리버스 엔지니어링 방법은 종종 효과가 없습니다. 따라서 내부에 저장된 펌웨어를 해독하고 디코딩하기 위해 디캡슐레이션(물리적 칩 개방), 메모리 전하 분석, 광학 이미징과 같은 특수한 접근 방식이 필요합니다.

Our proven process to copy IC PIC16F84A binary includes several stages:

1. Chip Readout & Flash Memory Access – We employ precise tools to open, readout, and decrypt the locked flash and EEPROM data, even if protective fuses are set.

2. Binary Extraction and Program Restoration – After extraction, we restore the original binary or heximal file, ensuring data integrity for duplication.

3. Firmware Analysis and Source Code Recovery – Once the program file is retrieved, our team can decode and replicate it into readable source code, allowing further modifications or migrations.

4. Firmware Duplication and Replication – Finally, the binary archive can be cloned or duplicated onto a new PIC16F84A or compatible microcontroller, helping clients expand their embedded systems without dependency on the original locked units.

The PIC16F84A stands apart due to its reprogrammable flash design, making it highly versatile but also more challenging to hack or replicate when security is enabled. Unlike other microcontrollers with simple security models, breaking into a secured PIC16F84A memory often requires non-invasive and invasive techniques combined.

Duplication et réplication du micrologiciel : enfin, l’archive binaire peut être clonée ou dupliquée sur un nouveau PIC16F84A ou un microcontrôleur compatible, permettant ainsi aux clients d’étendre leurs systèmes embarqués sans dépendre des unités verrouillées d’origine. Le PIC16F84A se distingue par sa conception Flash reprogrammable, ce qui le rend très polyvalent, mais aussi plus difficile à pirater ou à dupliquer lorsque la sécurité est activée. Contrairement à d’autres microcontrôleurs dotés de modèles de sécurité simples, l’intrusion dans une mémoire PIC16F84A sécurisée nécessite souvent une combinaison de techniques non invasives et invasives.

If you need to copy, clone, or replicate your protected firmware stored in a PIC16F84A, or if you have lost access to your original program files, Circuit Engineering Co., LTD offers a reliable and secure path to unlock and restore your critical embedded data.

The PIC16F8X is a group in the PIC16CXX family of low-cost, high-performance, CMOS, fully-static, 8-bit microcontrollers. This group contains the following devices:

· PIC16F83

· PIC16F84

Table 1-1 lists the features of the PIC16F8X. A simplified block diagram of the PIC16F8X is shown in Figure 3-1.

The PIC16F8X fits perfectly in applications ranging from high speed automotive and appliance motor control to low-power remote sensors, electronic locks, security devices and smart cards. The Flash/EEPROM technology makes customization of application after Copy microcontroller programs (transmitter codes, motor speeds, receiver frequencies, security codes, etc.) extremely fast and All PICmicro™ microcontrollers employ an advanced RISC architecture. PIC16F8X devices have enhanced core features, eight-level deep stack, and multiple internal and external interrupt sources.

The separate instruction and data buses of the Harvard architecture allow a 14-bit wide instruction word with a separate 8-bit wide data bus. The two stage instruction pipeline allows all instructions to execute in a single cycle, except for program branches (which require two cycles). A total of 35 instructions (reduced instruction set) are available. Additionally, a large register set is used to achieve a very high performance level.

PIC16F8X microcontrollers typically achieve a 2:1 code compression and up to a 4:1 speed improvement (at 20 MHz) over other 8-bit microcontrollers in their class. The small footprint packages make this microcontroller series perfect for all applications with space limitations.  Low-cost, low-power,  high performance, ease-of-use and I/O flexibility of making the PIC16F8X very versatile even in areas where no microcontroller use has been considered (e.g., timer functions; serial communication; capture, compare and PWM functions; and co-processor applications).

The serial in-system programming feature (via two pins) offers flexibility of customizing the product after complete assembly and testing. This feature can be used to serialize a product, store calibration data, or program the device with the current firmware before shipping after IC program can be restored.

The PIC16F8X has up to 68 bytes of RAM, 64 bytes of Data EEPROM memory, and 13 I/O pins. A timer/ Family and Upward Compatibility counter is also available.

The PIC16CXX family has special features to reduce external components, thus reducing cost, enhancing system reliability and reducing power consumption.

There are four oscillator options, of which the single pin RC oscillator provides a low-cost solution, the LP Those users familiar with the PIC16C5X family of microcontrollers will realize that this is an enhanced version of the PIC16C5X architecture. Please refer to Appendix A for a detailed list of enhancements. Code written for PIC16C5X devices can be easily ported to PIC16F8X devices (Appendix B). oscillator minimizes power consumption, XT is a standard crystal, and the HS is for High Speed crystals.

Development Support

The SLEEP (power-down) mode offers power saving.

The user can wake the chip from sleep through several external and internal interrupts and resets.

A highly reliable Watchdog Timer with its own on-chip RC oscillator provides protection against software lock-up.

The devices with Flash program memory allow the same device package to be used for prototyping and production. In-circuit reprogrammability allows the code to be updated without the device being removed from the end application.

This is useful in the development of many applications where the device may not be easily accessible, but the prototypes may require code updates. This is also useful for remote applications where the code may need to be updated (such as rate information)

The PIC16CXX family is supported by a full-featured macro assembler, a software simulator, an in-circuit emulator, a low-cost development programmer and a full-featured programmer. A “C” compiler and fuzzy logic support tools are also available.
