• Industrial automation and control panels
• Smart home devices
• Access control and security systems
• Mechatronics and robotics
• Custom embedded electronics

Because of its popularity, many legacy systems still rely on ATmega32A. In situations where firmware source code is lost, or a system integrator has gone out of business, the ability to restore or copy a locked firmware image is essential for maintenance, replication, or system upgrades.

The Microchip PIC16F870 microcontroller is widely used in industrial, commercial, and consumer products due to its reliability, compact size, and rich feature set. Equipped with flash memory, EEPROM, and a range of peripheral interfaces, the PIC16F870 is a popular choice for applications such as automation systems, smart appliances, motor control, and remote sensors.

However, when the firmware stored inside its flash or EEPROM is protected, locked, or encrypted, accessing, modifying, or restoring the original program becomes a complex task. That’s where Circuit Engineering CO.,LTD steps in. We specialize in services that copy, clone, duplicate, unlock, crack, hack, decode, decrypt, restore, and open the contents of secured microcontrollers like the PIC16F870.

The PIC16F870 features 2K words of Flash program memory, 128 bytes of EEPROM, and a full complement of peripherals including A/D converters, USART communication, and a versatile I/O configuration. Its popularity in critical embedded systems makes it essential to have the ability to recover or duplicate the internal binary, heximal, or source code when original files are lost or when reverse engineering is required.

Our Procedure to Copy Chip PIC16F870 Program

1. Chip Analysis
   First, we assess the specific security level applied to the PIC16F870. We determine if the flash, eeprom, or both have protective measures like read protection or encryption.

2. Unlocking the Protection
   Using advanced hardware and software tools, we safely crack, hack, or decrypt the microcontroller’s security layers without damaging the memory.

3. Data Extraction
   Once unlocked, we proceed to copy the entire program memory, eeprom data, and any configuration bits. This firmware is extracted as a complete binary or heximal file.

4. Decoding and Verification
   The extracted archive is decoded and carefully verified against the microcontroller’s operation to ensure data integrity.

5. Restoration or Duplication
   Depending on the client’s needs, we can restore the original program onto a blank PIC16F870, clone multiple units, or convert the extracted firmware into human-readable source code for further modification.

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.

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.

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.

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. Contact us today to learn more about how we can help you decapsulate, decode, and open your secured microcontroller archives.

Copy IC PIC16F84A Binary out from microcontroller PIC16F84A flash memory, and reprogramme the firmware into blank MCU PIC16F84A which will provide the same functions as original version, the status of master original MICROPROCESSOR PIC16F84A can be unlocked;

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.

In the world of embedded systems, accessing and duplicating secured microcontrollers is often essential for product maintenance, migration, and system upgrades. One such frequently used microcontroller is the AT89S8252, an 8051-based device from Atmel (now Microchip), known for its built-in flash memory, EEPROM, and high-performance architecture. At [Your Company Name], we offer specialized services to copy chip AT89S8252 flash, helping clients unlock, readout, and replicate protected firmware from embedded systems.

When a microcontroller like the AT89S8252 is deployed in commercial or industrial systems, its firmware is often encrypted, locked, or secured with protective memory configurations to prevent unauthorized access. While this protection enhances security, it can also be an obstacle when legitimate recovery, duplication, or system analysis is required. Our service is designed to crack, decode, and open locked flash archives for clients who need to access their own systems or legally replicate legacy hardware and firmware.

Unlocking the Value of Legacy Embedded Systems

Many companies rely on legacy hardware platforms with embedded microcontrollers like the AT89S8252. However, over time, documentation, source code, or development tools may become unavailable. In such cases, our ability to restore and replicate embedded flash and EEPROM memory becomes invaluable. We help our clients copy and duplicate the flash contents of secured chips, enabling them to maintain production, repair critical systems, or migrate to new hardware platforms without rewriting entire firmware packages from scratch.

Our solutions ensure the safe readout and backup of binary or heximal program files, preserving the full operational behavior of the original embedded device. Whether you’re looking to replicate locked program data, decrypt encrypted firmware archives, or simply clone the contents of a protective chip, we have the tools and experience to deliver accurate and reliable results.

Comprehensive Firmware Recovery and Cloning Services

We serve a wide range of industries that rely on the integrity of firmware and memory data in their embedded controllers. Our services are often used to break open locked flash memory, decrypt proprietary binary code, or duplicate secured program files for product recovery and system continuity. These solutions are especially critical when dealing with protected embedded files that cannot be easily recompiled or replaced due to the absence of source code or original development teams.

By offering advanced techniques to unlock and replicate flash and EEPROM memory archives, we provide our clients with peace of mind—knowing their embedded systems can be supported long after the original manufacturer has moved on.

Description

The AT89S8252 is a low-power, high-performance CMOS 8-bit microcontroller with 8K bytes of downloadable Flash programmable and erasable read-only memory and 2K bytes of EEPROM. The device is manufactured using Atmel’s high-density nonvolatile memory technology and is compatible with the industry-standard 80C51 instruction set and pinout.

The on-chip downloadable Flash allows the program memory to be reprogrammed In-System through an SPI serial interface or by a conventional nonvolatile memory programmer. By combining a versatile 8-bit CPU with downloadable Flash on a monolithic chip, the Atmel AT89S8252 is a powerful microcontroller, which provides a highly-flexible and cost-effective solution to many embedded control applications.

The AT89S8252 provides the following standard features: 8K bytes of downloadable Flash, 2K bytes of EEPROM, 256 bytes of RAM, 32 I/O lines, programmable watchdog timer, two data pointers, three 16-bit timer/counters, a six-vector two-level interrupt architecture, a full duplex serial port, on-chip oscillator, and clock circuitry.

In addition, the Copy Chip AT89S8252 is designed with static logic for operation down to zero frequency and supports two software selectable power saving modes. The Idle Mode stops the CPU while allowing the RAM, timer/counters, serial port, and interrupt system to continue functioning. The Power-down mode saves the RAM contents but freezes the oscillator, disabling all other chip functions until the next external interrupt or hardware reset.

The downloadable Flash can be changed a single byte at a time and is accessible through the SPI serial interface. Holding RESET active forces the SPI bus into a serial programming interface and allows the program memory to be written to or read from unless lock bits have been activated.

The PIC16F684 microcontroller from Microchip is a popular choice for compact, low-power embedded applications. It is frequently found in consumer electronics, industrial controls, automotive systems, and security devices. Its cost-efficiency, reliability, and rich feature set make it ideal for a range of embedded projects. However, when developers or engineers need to copy microcontroller PIC16F684 firmware, they often face challenges due to protective mechanisms such as code locking, encryption, and memory protection fuses.
