Acroview, the leader in chip programming, has officially announced the further expansion of its compatible chip model coverage with the release of a new version of its programming software. The company's core product – the universal programming platform AP8000 – has now achieved full adaptation with SynWit's 32-bit microcontroller SWM34SVET.

The SWM34SVET is a 32-bit microcontroller based on the Arm China STAR-MC1 core. It features high performance, low power consumption, and high code density, making it suitable for industrial control, white goods, motor drive, and many other application fields.

The SWM34SVET embeds the Arm China STAR-MC1 controller with a single-precision floating-point unit (FPU), supporting all ARM single-precision data processing instructions and data types. It also includes a set of DSP instructions and a Memory Protection Unit (MPU) to improve application security. The on-chip clock of 20MHz/40MHz with accuracy within 1% can be multiplied via PLL to 150MHz. Various built-in FLASH/SRAM sizes are available, and the SWM34SVET is respectively stacked with 2/8/16M Bytes SDRAM options. It supports ISP (In-System Programming) and IAP (In-Application Programming). Peripheral serial buses include CAN interfaces, multiple UART interfaces, SPI communication interfaces (supporting master/slave/I2S mode selection), and I2C interfaces (supporting master/slave selection). In addition, it includes one 32-bit watchdog timer, five 32-bit enhanced timers, twelve 24-bit basic timers, ten independent 16-bit PWM generators, two successive approximation ADC modules with a total of 16 channels, 12-bit resolution, and 2.5MSPS sampling rate, one TFT-LCD driver module, one SDIO interface, one JPEG image hardware decoder, one DAC module, one RTC real-time clock, and one external SDRAM interface control module, along with brown-out detection and low-voltage reset functions.

Functional Block Diagram

The AP8000 universal programmer independently developed by Acroview has become a benchmark professional programming solution in the industry. The device supports flexible and configurable one-to-one and one-to-eight configuration modes, and provides both online and offline working modes. It has developed dedicated programming solutions for storage chips such as eMMC and UFS, and can fully cover the bare-chip offline programming and on-board programming needs of SynWit's full series of chips. The AP8000 adopts an innovative modular design with three core modules – mainframe, baseboard, and adapter socket – endowing the device with excellent compatibility and expandability. As a universal programming platform, it not only adapts to various programmable chips on the market, but also serves as a core component of Acroview's automated batch programming system IPS5800S with stable and efficient performance, capable of handling large-scale chip programming tasks and meeting mass production requirements.

The AP8000 mainframe features flexible connectivity, equipped with both USB and NET interfaces, enabling convenient networking of multiple programmers. Through networking, users can easily achieve synchronized control of multiple programmers and efficiently carry out parallel programming operations. In terms of security, the mainframe has a built-in intelligent safety protection circuit that monitors chip placement status and circuit connections in real time. Once abnormalities such as reverse insertion or short circuits are detected, it immediately triggers a power-off protection mechanism, comprehensively safeguarding the safe operation of both chips and the programmer. The mainframe is equipped with a high-speed FPGA chip, significantly improving data transmission and processing efficiency to ensure a smooth and efficient programming process. To enhance user convenience, an SD card slot is provided on the back of the mainframe. Users only need to save the project file generated on the PC to an SD card and insert it into the slot, then use the physical buttons on the programmer to select, load, and execute programming operations, enabling stand-alone operation without a PC. This design not only reduces dependency on computer hardware specifications but also simplifies the working environment setup, significantly improving operational flexibility.

In terms of expandability and compatibility, the AP8000 adopts a modular combination design of baseboard and adapter boards, effectively extending the mainframe's functional boundaries. Currently, the device supports products from all major semiconductor manufacturers, covering well-known brands such as SK hynix, Micron, SANDISK, ASR, and Kingston. Its supported device types are extensive, including NAND, NOR, MCU, CPLD, FPGA, EMMC, and more, and it is fully compatible with multiple industry-standard file formats such as Intel Hex, Motorola S, Binary, and POF, providing users with a one-stop, full-scenario chip programming solution.
