The industry leader in chip programmer, Acroview Technology, recently released the latest programming software update and added support for a list of chip models. Among them, the 32-bit microcontroller HC32F4A0RIT from HDSC Huada Semiconductor has been supported by Acroview's universal programming platform AP8000.

HC32F4A0RIT is based on the ARM® Cortex®-M4 32-bit RISC CPU, with a maximum operating frequency of 240MHz, making it a high-performance MCU. The Cortex-M4 core integrates a floating-point unit (FPU) and DSP, enabling single-precision floating-point arithmetic operations, supporting all ARM single-precision data processing instructions and data types, and a complete DSP instruction set. The core integrates an MPU unit and overlays a dedicated DMAC MPU unit to ensure system security during operation.

HC32F4A0RIT integrates high-speed on-chip memory, including a maximum of 2MB of Flash and a maximum of 512KB of SRAM. It also integrates a Flash access acceleration unit, enabling the CPU to execute programs in a single cycle on the Flash. The polling bus matrix supports multiple bus masters simultaneously accessing memory and peripherals, improving operational performance. Bus masters include the CPU, DMA, USB dedicated DMA, and ETHMAC dedicated DMA. In addition to the bus matrix, it supports data transfer between peripherals, basic arithmetic operations, and event triggering, significantly reducing the CPU's transaction processing load.

The HC32F4A0RIT integrates rich peripheral functions. It includes 3 independent 12-bit 2.5MSPS ADCs, 4 adjustable gain PGAs, 4 12-bit 15MSPS DACs, 4 high-speed voltage comparators (CMP), 8 multifunctional PWM timers (Timer6), supporting 16 complementary PWM outputs, 16 high-precision PWMs (HRPWM extends the resolution of Timer6's PWM signal), 3 motor PWM timers (Timer4) supporting 18 complementary PWM outputs, 12 16-bit general timers (TimerA) supporting 6 3-phase orthogonal encoding inputs and 48 independent configurable PWM outputs, 22 serial communication interfaces (I2C/UART/SPI), 1 QSPI interface, 2 CAN, 4 I2S supporting audio PLL, 2 SDIO, 1 ETHMAC, USBFS Controller with built-in USBFS PHY and USBHS Controller, 1 external expansion bus controller, including NFC controller, SMC controller, and DMC controller, 1 digital video interface DVP, 1 mathematical operation unit (MAU), and 4 filtering mathematical accelerators (FMAC).

The HC32F4A0RIT supports a wide voltage range (1.8-3.6V), wide temperature range (-40-105°C), and various low power modes. It supports fast wake-up in low power modes, with a wake-up time as fast as 2us in STOP mode and 25us in Power Down mode.

Typical Applications HC32F4A0RIT is used in high-performance inverter control, digital power, smart hardware, IoT connectivity modules and other fields.

Functional Block Diagram

Acroview Technology's independently developed AP8000 universal programmer includes three main parts: the host, the baseboard, and the adapter seat.

The host supports USB and NET connections, allowing multiple programmers to be networked together to simultaneously control and programme multiple programmers. The built-in chip security circuit ensures that even if the chip is reversed or short-circuited for other reasons, it can be immediately detected and powered off to ensure the safety of the chip and programmer. The embedded high-speed FPGA greatly accelerates data transmission and processing. The back of the host has an SD card slot, where engineering files created by PC software can be placed in the root directory of the SD card and inserted into the slot. Through the buttons on the programmer, engineering files can be selected, loaded, and programming commands can be executed, achieving the purpose of operation without a PC, greatly reducing PC hardware configuration costs and facilitating rapid adaptation to the working environment.

The AP8000, through the baseboard and adapter board, enhances the expandability of the host. It currently supports devices produced by all mainstream semiconductor manufacturers, including TI, ST, MicroChip, Atmel, Hynix, Macronix, Micron, Samsung, Toshiba, etc. The supported device types include NAND, NOR, MCU, CPLD, FPGA, EMMC, etc., and support various file formats such as Intel Hex, Motorola S, Binary, POF, etc.
