ACROVIEW Technology, a leader in chip programming, announced the expansion of its compatible chip model list with the release of its new programming software. The newly added model includes the MP4201 buck-boost converter and controller from MPS Semiconductor, which has been supported by the ACROVIEW universal programming platform AP8000.

The MP4201 integrates synchronous four-switch N-channel MOSFET drivers and a bidirectional buck-boost controller, supporting GaN devices, capable of adjusting output voltage across a wide input voltage range, and features high efficiency.

This device provides one-time programmable (OTP) memory and an I2C interface for configuring output voltage (VOUT), VOUT slope control, and input and output current limits. The MP4201 is suitable for USB standard power range (SPR) and extended power range (EPR) power delivery (PD) designs and high-power systems.

The MP4201 offers an optional forced continuous conduction mode (FCCM) and automatic pulse frequency modulation (PFM)/pulse width modulation (PWM). It also provides battery charging control and configurable switching frequency (fSW), with frequency spectrum spreading (FSS) functionality to support flexible designs for various applications.

The MP4201 integrates battery charging cycle control and precise battery voltage regulation features, pre-charge, constant current (CC) and constant voltage (CV) charging, cutoff charging detection, and status indication functions. It also provides configurable input current (IIN) and output current (IOUT) overcurrent protection (OCP), configurable VIN regulation thresholds for power supply protection, and over-temperature shutdown protection.

The MP4201 is packaged in a QFN-32 (5x6mm) package.

With a strong technical foundation, ACROVIEW’s self-developed AP8000 universal programmer is regarded as a benchmark-level programming solution in the industry. This device supports flexible one-to-one and one-to-eight configurations, while providing both online and offline operating modes. It has also developed dedicated programming solutions for eMMC and UFS storage chips, fully meeting the bare chip offline programming and on-board programming needs ofMPS Semiconductor’s entire series of chips. The AP8000 consists of three core modules: host, baseboard, and adapter, and this modular design grants it excellent compatibility and expandability. As a universal programming platform, the AP8000 can adapt to various programmable chips on the market and, due to its stable and efficient performance, has become the core component of ACROVIEW’s automated IPS5800S programming system, efficiently handling large-scale chip programming tasks to meet mass production needs.

The AP8000 host features flexible connectivity options, equipped with USB and NET interfaces, allowing for easy networking of multiple programmers. Through the networking function, users can easily achieve synchronized control of multiple programmers, efficiently conducting parallel programming operations. In terms of safety, the host is equipped with an intelligent safety protection circuit that can monitor the chip placement status and circuit connection in real-time. If it detects abnormal conditions such as chip reverse insertion or short circuits, it will immediately trigger a power-off protection mechanism, fully safeguarding the safe operation of the chip and programmer. The host is equipped with a high-speed FPGA chip, significantly enhancing data transmission and processing efficiency, ensuring a smooth and efficient programming process. To enhance user convenience, the back of the host is equipped with an SD card slot, allowing users to store project files generated on the PC to the SD card and insert it into the slot. They can then complete file selection and loading for programming operations through the physical buttons on the programmer, achieving independent operation without a PC. This design not only reduces dependence on computer hardware configurations but also simplifies the setup process of the working environment, significantly enhancing operational flexibility.

In terms of expandability and compatibility, the AP8000 adopts a modular design of baseboard and adapter board, effectively extending the functional boundaries of the host. Currently, this device has achieved support for products from all major semiconductor manufacturers, covering well-known brands such as QUECTEL, BEKEN, Elmos, Nation, HiTrendtech, etc. 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, POF, providing users with a one-stop, all-scenario chip programming solution.
