The STM32F215 family of MCUs is targeted at medical, industrial, and consumer applications that require highly integrated, high-performance, embedded memory, and peripherals in packages as small as 10 x 10 mm.

The STM32F427/437 microcontroller integrates the CortexTM-M4 core (with floating point unit) operating at 180 MHz, and its static power consumption (stop mode) is lower than STM32F215RET6.

Performance: At 180 MHz, the STM32F215RET6 microcontroller uses ST’s ART accelerator to provide 225 DMIPS/608 CoreMark performance in zero latency when executing from Flash memory. DSP instructions and floating-point units expand the range of applications.

It consumes 100 μA (typical) in shutdown mode, which is three times lower than the STM32F215 unlock IC successfully.

Rich connectivity: outstanding innovative peripherals

Graphics: STM32F215RET6 In contrast, the STM32F215RET6 MCU does not have an integrated LCD-TFT controller interface. However, it can connect to the display via a parallel or serial interface and use ST’s Chrom-ART graphics accelerator for content creation twice the kernel’s speed. In addition to raw data copying, the Chrom-ART AcceleratorTM supports other features such as image format conversion and image blending (specified transparency for image blending). As a result, the Chrom-ART Accelerator accelerates image content creation and saves the MCU core’s processing bandwidth for the rest of the application.

Recently, the company successfully developed a certain X3 electric unicycle. The chip used in its primary control is ST’s ARM chip STM32F103C8T6. The technical engineer of our company successfully carried out chip decryption and MCU crack on STM32F103C8T6. Customers with similar needs are welcome to contact us.

STM32F105 unlock successfully:

ST series of ARM chips, there is a unique ID number encryption. Usually, we unlock soft encryption to remove the ID number encryption. Still, recently in the process of reverse development of the entire system for the guests, we found a readable When the chip AT45DB041E was read and then burned, it found that it could not work usually. After careful investigation, the chip and the main chip STM32F105 were bound to each other. After verification, AT45DB041E did have a globally unique ID number. This encryption method is usually Used for boot detection; the main chip will not start when the check fails.

After understanding the whole encryption method, our engineers reverse-compiled the main control chip STM32F105, found the corresponding encryption code, skipped the FLASH verification directly, and finally wholly cloned.

Our company specializes in IC unlock, binary code reverse development, etc. Our company can currently unlock all STM32 series encryption chips on the market in the long-term work accumulation.
