Acroview Technology, a leader in chip programming, while releasing a new version of its programming software, officially announced further expansion of its compatible chip model coverage. Its core product, the AP8000 universal programming platform, has now achieved full compatibility with LowPowerSemi's programmable multi-function power IC LP6281H.

LP6281H is a programmable multi-function power IC for TFT-LCD that integrates gamma buffers and a VCOM1 buffer. The chip integrates: 1 AVDD boost converter/controller, 1 isolation MOS controller for AVDD power-up sequencing control, 1 VBK buck converter, 1 VGH boost converter with temperature compensation, 1 VGL inverting converter, 1 VSS negative voltage regulator, 14-channel gamma buffers, and 2-channel VCOM buffers. The output levels and timing of all channels can be configured through the I2C interface and on-chip multiple-time programmable (MTP) non-volatile memory.

LP6281H features high-current output capability and a wide supply voltage range, making it well suited for large-screen LCD TV/monitor (MNT) panels. The chip also integrates a full set of protection mechanisms, including overvoltage protection (OVP), undervoltage protection (UVP), overcurrent protection (OCP), and over-temperature protection (OTP).

LP6281H is available in a QFN 6.5×4.5mm, 46-pin package.

Internal Block Diagram

Acroview's independently developed AP8000 universal programmer has become an industry benchmark professional programming solution. The device supports flexible one-to-one and one-to-eight configurations and provides both online and offline working modes. It has developed dedicated programming solutions especially for memory chips such as eMMC and UFS, fully covering LowPowerSemi's entire chip series for bare die offline programming and on-board programming requirements. AP8000 adopts an innovative modular design with three core modules—host, bottom board, and adapter socket—giving the device excellent compatibility and scalability. As a universal programming platform, it can not only adapt to various programmable chips on the market, but also, with stable and efficient performance, serves as the core component of Acroview's automated batch programming equipment IPS5800S, efficiently handling large-scale chip programming tasks and meeting mass production requirements.

The AP8000 host offers flexible connection options and is equipped with USB and NET interfaces, enabling convenient networking of multiple programmers. Through the networking function, users can easily achieve synchronous control of multiple programmers and efficiently carry out parallel programming operations. In terms of safety, the host has a built-in intelligent safety protection circuit that monitors chip placement and circuit connection status in real time. If abnormalities such as reversed chip insertion or short circuits are detected, power-off protection is triggered immediately, safeguarding both the chip and the programmer. The host is equipped with a high-speed FPGA chip, greatly improving data transmission and processing efficiency and ensuring a smooth and efficient programming process. To enhance usability, an SD card slot is provided on the back of the host. Users only need to save project files generated on a PC to an SD card and insert it into the slot; then they can select, load, and program files via the physical buttons on the programmer, enabling standalone operation without a PC. This design not only reduces dependence on computer hardware configuration, but also simplifies work environment setup and significantly improves operational flexibility.

In terms of scalability and compatibility, AP8000 adopts a modular combination design of bottom board and adapter board, effectively expanding the functional boundaries of the host. At present, the device supports products from all mainstream semiconductor manufacturers, covering well-known brands such as SK hynix, Micron, SANDISK, ASR, and Kingston. It supports a wide range of device types, including NAND, NOR, MCU, CPLD, FPGA, EMMC, etc., and is fully compatible with various industry-standard file formats such as Intel Hex, Motorola S, Binary, and POF, providing users with one-stop, full-scenario chip programming solutions.
