ACROVIEW, a leader in chip programming, recently announced the latest iteration of its programming software, unveiling a series of newly compatible chip models. In this update, the automotive-grade 8-bit microcontroller STM8AF52A8T from STMicroelectronics has been supported by ACROVIEW’s top programming tool, the AP8000.
The STM8AF52A8T automotive-grade 8-bit microcontroller offers non-volatile memory ranging from 32Kbyte to 128Kbyte and integrates true data EEPROM. The STM8AF52A8T features a CAN interface. All devices in the STM8A product line provide the following advantages: reduced system costs, improved performance and robustness, shortened development cycles, and extended product lifetimes.
The STM8AF52A8T reduces system costs due to its integration of true data EEPROM capable of withstanding up to 300,000 erase cycles, along with an internal clock oscillator, watchdog, and undervoltage reset, achieving high system integration. Device performance is ensured with a 20MIPS (Million Instructions Per Second) at a 24MHz CPU clock frequency, enhanced by robust I/O, an independent watchdog (with its own clock source), and a clock security system.
Thanks to its universal product series architecture, which features compatible pin configurations, memory mapping, and modular peripherals, it guarantees a shorter development cycle. Additionally, comprehensive documentation and a wide selection of development tools are provided.
The STM8AF52A8T employs advanced core technology designed for automotive applications operating at power supplies of 3.3V to 5.5V, ensuring long product lifetimes.

Internal Block Diagram
The AP8000 universal programmer developed by ACROVIEW is a powerful programming solution that supports both online and offline versions in one-to-one and one-to-eight configurations, while also providing dedicated programming solutions for eMMC and UFS, fully meeting the bare chip (offline) and on-board programming needs for all ST series chip models. The AP8000 consists of three core components: the host, the baseboard, and the adapter, serving as an industry-leading universal programming platform that not only meets the programming needs of various programmable chips on the market but also serves as the core programming platform for ACROVIEW’s bulk programming device IPS5800S, efficiently supporting large-scale programming tasks.
The host supports both USB and NET connections, enabling networking of multiple programmers to synchronize control of multiple programmers for programming operations. The built-in safety protection circuit can instantly detect abnormal situations such as reversed chip placement or short circuits, and immediately cut off power to ensure the safety of both the chip and the programmer. The host integrates a high-speed FPGA, significantly enhancing data transmission and processing speeds. The back of the host features an SD card slot, allowing users to save project files generated by PC software to the root directory of the SD card and insert it into the slot. By using the button on the programmer, users can select, load, and execute programming instructions without relying on a PC, which not only reduces the hardware configuration costs of the PC but also facilitates the rapid construction of the working environment.
The AP8000 enhances the host’s expansion capabilities through the combination design of the baseboard and adapter, currently supporting products from all major semiconductor manufacturers, including ANALOG DEVICES, Onsemi, ISSI, MXIC, ABLIC, and others. The supported device types include NAND, NOR, MCU, CPLD, FPGA, EMMC, etc., and it is compatible with various file formats such as Intel Hex, Motorola S, Binary, POF, etc.
